Overview

The IEC 61010-2-2xx documents represents a series of standards on the safety of measurement, control, and automation equipment for industrial processes. This document specifies the complete safety-related requirements and associated tests for control devices (for example, programmable logic controllers (PLCs), the components of distributed control systems (DCS), I/O devices, and human-machine interfaces (HMIs)). The safety terms used in general are defined in IEC 61010-1. More specific terms are defined in each relevant part of the IEC 61010 series of standards. This third edition of the International Standard IEC 61010-2-201 "Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-201: Particular requirements for control equipment" replaces the second edition of the standard, published in 2017. This edition represents a technical revision and includes, among other things, the significant technical changes listed below compared to the previous edition. A list of all parts of the IEC 61010 series of International Standards under the general title "Safety requirements for electrical equipment for measurement, control and laboratory use" can be found on the IEC website (www.iec.ch). This document is to be used in conjunction with IEC 61010-1:2010, and IEC 61010 1:2010/AMD1:2016. IEC 61010-2-201 supplements or modifies the corresponding clauses in IEC 61010-1 so as to convert that publication into the IEC 61010-2-201 standard "Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-201: Particular requirements for control equipment". Where a particular clause or subclause of IEC 61010-1 is not mentioned in this Part 2-201 of the IEC 61010 series of standards, then that clause applies as far as is reasonable. Where this Part states "addition", "modification", "replacement", or "deletion", the correspondingly adapted text of IEC 61010-1 shall apply. In this standard: a) the following fonts are used: - Requirements: in standard type; - in lower case; - Tests: in italics; - terms used throughout this standard and defined in Clause 3: IN SMALL CAPS; b) subclauses, figures, tables, and notes that have been added compared to Part 1 are consecutively numbered beginning with 101. Additional annexes are designated beginning with AA, and additional list items are designated beginning with aa). This standard does not deal with aspects of the overall automated system, such as a complete assembly line. Control equipment (for example, 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 (for example, 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. This standard does not cover: a) reliability, functionality, performance, or other properties of the control equipment not related to safety; b) mechanical or climatic requirements for operation, transport or storage; c) EMC requirements (see, for example, IEC 61326 or IEC 61131-2); d) protective measures for explosive atmospheres (see, for example, IEC 60079 series); e) functional safety (see, for example, IEC 61508, IEC 61131-6). The standard differs from DIN EN IEC 61010-2-201 (VDE 0411-2-201):2019-04 and DIN EN IEC 61010-2-201 Corrigendum 1 (VDE 0411-2-201 Corrigendum 1):2020-01 as follows: a) 1.1.1: the related equipment included in the Scope has been clarified; b) 4.3.2.101: the optical fibre module has been deleted; c) 5.4.3: equipment installation has been clarified; d) 6.7.1.1: revision of the figure representing insulation between separate circuits has been included; e) 6.7.101: the subclause relating to insulation for FIELD WIRING TERMINALS of OVERVOLTAGE CATEGORY ll with a nominal voltage up to 1 000 V has been deleted; f) 6.7.1.101: a new subclause relating to insulation for SELV/PELV CIRCUITS has been included; g) 6.8.3: specification of voltage tester has been added; h) 6.9.3: an additional exception relating to colour coding has been included; i) 6.9.101: a new subclause relating to wiring for secondary circuits, such as SELV/PELV has been included; j) 8.2.2.101: additional requirements for glass displays have been included; k) 8.3: the subclause relating to the drop test has been removed; l) 9.3.2: additional requirements for material of connectors and insulating material have been included; m) the particular requirements for non-metallic material have been clarified; n) Clause 11: the particular requirements for protection against HAZARDS from fluid and solid foreign objects have been removed; o) 12.4: an additional subclause relating to microwave radiation has been included; p) 14.102: the description of switching devices has been clarified. 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, for example: - (auxiliary) stand-alone power supplies; - peripherals such as digital and analogue I/O, - remote-I/O; - industrial network equipment, embedded or standalone (for example switches, routers, wireless base station (WLAN)). Control equipment and their associated peripherals are intended to be used in an industrial environment and may be provided as OPEN or ENCLOSED EQUIPMENT. 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. Computing devices and similar equipment within the scope of the IEC 60950 series of standards or the IEC 62368 series of standards 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 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. 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. 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.
