Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-201: Particular requirements for control equipment (IEC 61010-2-201:2024)
This clause of Part 1 is applicable, except as follows.
1.1.1 Equipment included in scope
Replacement:
This part of IEC 61010 specifies safety requirements and related verification tests for control equipment and/or their associated peripherals.
Some equipment examples are:
- programmable logic controller (PLC);
- programmable automation controller (PAC);
- distributed control systems (DCS);
- industrial PC (computers) and panel PC;
- programming and debugging tools (PADTs);
- displays and human-machine interfaces (HMI);
- any product performing the function of control equipment and/or their associated peripherals;
- positioners; and
- control equipment which have as their intended use the command and control of machines, automated manufacturing and industrial processes, e.g. discrete and continuous control.
Components of the above named equipment and in the scope of this standard are e.g.:
- (auxiliary) stand-alone power supplies;
- peripherals such as digital and analogue I/O,
- remote-I/O;
- industrial network equipment, embedded or standalone (e.g. switches, routers, wireless base station).
Control equipment and their associated peripherals are intended to be used in an industrial environment and may be provided as OPEN or ENCLOSED EQUIPMENT.
NOTE 1 Control equipment intended also for use in other environments or for other purposes (example: for use in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have additional conformity requirements defined by the safety standard(s) for these applications. These requirements can involve as example: insulation, spacings and power restrictions.
NOTE 2 Computing devices and similar equipment within the scope of IEC 60950 (planned to be replaced by IEC 62368) and conforming to its requirements are considered to be suitable for use with control equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in IEC 61010-1:2010, 5.4.4 second paragraph.
Control equipment covered in this standard is typically intended 237 for use in OVERVOLTAGE CATEGORY II (IEC 60664-1) in low-voltage installations, where the RATED equipment supply voltage does not exceed AC. 1 000 V r.m.s. (50/60 Hz), or DC 1 000 V.
Where control equipment is intended for installation to supply systems with overvoltage category III or IV, additional requirements are identified in Annex K.
The requirements of ISO/IEC Guide 51 and IEC Guide 104, as they relate to this part of IEC 61010, are incorporated herein.
1.1.2 Equipment excluded from scope
Replacement:
This standard does not deal with aspects of the overall automated system, e.g. a complete assembly line. Control equipment (e.g. DCS and PLC), their application program and their associated peripherals are considered as components (components in this context are items which perform no useful function by themselves) of an overall automated system.
Since control equipment (e.g. DCS and PLC) are component devices, safety considerations for the overall automated system including installation and application are beyond the scope of this standard. Refer to IEC 60364 series of standards or applicable national/local regulations for electrical installation and guidelines.
1.2.1 Aspects included in scope
Replace first sentence:
The purpose of the requirements of this standard is to ensure that all HAZARDs to the OPERATOR, SERVICE PERSONNEL and the surrounding area are reduced to a tolerable level.
NOTE By using the terms "OPERATOR" and "SERVICE PERSONNEL" this standard considers the perception of HAZARDS depending on training and skills. Annex AA gives a general approach in this regard.
1.2.2 Aspects excluded from scope

87 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
88 FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
90 Part 2-201: Particular requirements for control equipment
92 FOREWORD
93 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
94 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
95 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
96 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
97 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
98 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
99 in the subject dealt with may participate in this preparatory work. International, governmental and non-
100 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
101 with the International Organization for Standardization (ISO) in accordance with conditions determined by
102 agreement between the two organizations.
103 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
104 consensus of opinion on the relevant subjects since each technical committee has representation from all
105 interested IEC National Committees.
106 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
107 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
108 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
109 misinterpretation by any end user.
110 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
111 transparently to the maximum extent possible in their national and regional publications. Any divergence
112 between any IEC Publication and the corresponding national or region
