Industrial-process control systems - Instruments with analogue inputs and two- or multi-position outputs - Part 2: Guidance for inspection and routine testing


Do you need a multi-user copy?




IEC 61003-2:2016 gives guidelines for inspection and routine testing of electrical and pneumatic instruments with two- or multi-position output, for instance, for acceptance tests or after repair. It is applicable to electrical and pneumatic industrial-process instruments, using measured values that are continuous signals. The set point value may be either a mechanical (position, force, etc.) or a standard signal. These instruments may be used as controllers or as switches for alarms and other similar purposes. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- use of the term "two- or multi-position output" instead of "two- or multi-state instrument" (see Scope);
- use of the term "differential gap" instead of "switching differential" (see Table 1 No 2);
- use of the term "dielectric strength" instead of "isolation test" (see Table 1 No 5).

This publication is to be read in conjunction with IEC 61003-1:2016, IEC 61298-2:2008 and IEC 61298-3:2008
