TELECONTROL EQUIPMENT AND SYSTEMS
Part 1: General considerations
Section Two - Guide for specifications
INTRODUCTION
Planning of telecontrol systems and defining the specifications of a
system and of its equipment are complex and demand a large amount of
detailed information. There are not only application functions of the
system to be defined but also the operational parameters, the local
environmental conditions and the data transmission paths available as
well as their characteristics. The interfaces between the components of
the system and other equipment facilities such as power supply require-
ments shall also be specified.
Many aspects of this field are covered by standards within the
IEC 870 series on telecontrol equipment and s, stems but many deci-
sions are still left to the engineers who have to plan a system and
establish the specifications.
1. Scope
This series of standards applies to telecontrol equipment and systems
with coded bit serial data transmission for monitoring and control of
geographically widespread processes.
2. Object
This section presents guidelines but not standards for establishing
specifications for telecontrol systems and equipment following the other
IEC standards on telecontrol systems and other relevant international
standards and recommendations such as CCITT recommendations. It
also facilitates the comparison of equipment of different manufacturers.
The planning of telecontrol systems should be subdivided into clearly
defined steps:
- The first step involves a consideration of the operational require-
ments of telecontrol systems (clause 3 of this section) .
-
In the second step, the conditions and limitations of the data
transmission network are considered and the most suitable utili-
zation is specified (clause 4 of this section) .
870-1-2 © IEC - 11 -
Thirdly, the required facilities for the telecontrol equipment and
other equipment of telecontrol systems are specified. This includes
considerations of whether it is useful to include existing local
control equipment (clause 5 of this section) .
The guidelines given in this section are applicable also if only parts
of telecontrol systems are needed. In this case only the relevant
clauses need be considered.
3.
Description of the telecontrol system and its functions
Design aim of the system, for example:
"Main (or regional) control system." (name of the power company
or of the region), or
"District telecontrol system." (name of the district itself or of
the district control centre), or
"Telecontrol system for power station." (name of the controlled
station) .

passing through the individual sections of telecontrol systems, but
also influenced by the network configuration, priority, accumu-
lation of events, etc.);
- parameters for state information, such as separating capability,
time resolution, suppression time, etc.;
- updating time for measured values and set point commands;
etc.
It should be emphasized that in specifying the above-mentioned
parameters the requirements of the process should be considered.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

lnternational Standard IEC 61837-2 has been prepared by lEC technical committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control,
selection and detection.
In this edition, types of enclosures are renamed to express their features in their names for
better understanding. The relative comparison of new types with old ones is listed in Table. 1.
New names of enclosures express configuration type, terminal lead numbers, sizes and
arrangement of terminal pads. The details of definition are shown in Clause 3: Configuration of
enclosures, and Clause 4: Designation of types.
Enclosures in this new edition are based on IEC 61240. In this standard, 27 enclosures are
added to the first edition of IEC 61837-2, as follows:
QCC-12/1407A, DCC-2/1206A, QCC-10/9272A, DCC-4/9070A, DCC-2-8045B, DCC-6/7834B,
DCC-6/7050A, QCC-10/7050A, DCC-4/6035C, DCC-2/6035C, QCC-8/5045A, DCC-4/5032A,
DCC-4/5032C, DCC-2/4818C, DCC-2/4115C, QCC-8/3838A, DCC-6/3838A, DCC-4/3225C,
DCC-2/3215C, QCC-8/3030B, DCC-6/3030A, DCC-6/2520A, DCC-4/2520C, DCC-4/2020C,
DCC-4/2016C, DCC-4/1612C, DCC-2/1612C.
As a result, the new version (the second edition) contains a total of 38 enclosure types, which
are listed in Table 1 – Designation of ceramic enclosures.
This standard is to be read in conjunction with IEC 61240.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.

piezoelectric devices for frequency control and selection – Standard outlines and terminal lead
connections, can be found on the IEC website.
The committee has decided that the contents of the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
lnternational Standard IEC 61837-2 has been prepared by lEC technical committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency control,
selection and detection.
This second edition cancels and replaces the first edition published in 2000. It constitutes a
technical revision.
In this edition, types of enclosures are renamed to express their features in their names for
better understanding. The relative comparison of new types with old ones is listed in Table. 1.
New names of enclosures express configuration type, terminal lead numbers, sizes and
arrangement of terminal pads. The details of definition are shown in Clause 3: Configuration of
enclosures, and Clause 4: Designation of types.
Enclosures in this new edition are based on IEC 61240. In this standard, 27 enclosures are
added to the first edition of IEC 61837-2, as follows:
– 4 – 61837-2 © IEC:2011

As a result, the new version (the second edition) contains a total of 38 enclosure types, which
are listed in Table 1 – Designation of ceramic enclosures.
This standard is to be read in conjunction with IEC 61240.
The text of this standard is based on the following documents:
CDV Report on Voting

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
A list of all parts of the IEC 61837 series, published under the general title: Surface mounted
piezoelectric devices for frequency control and selection – Standard outlines and terminal lead
connections, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to
the specific publication. At this date, the publication will be
‡ reconfirmed,
‡ withdrawn,
