IEC 61811-1:2015 applies to electromechanical telecom elementary relays. Relays according to this standard are provided for the operation in telecommunication applications. However, as electromechanical elementary relays, they are also suitable for particular industrial and other applications. This standard selects from IEC 61810 series and other sources the appropriate methods of test to be used in detail specifications derived from this specification, and contains basic test schedules to be used in the preparation of such specifications in accordance with this standard. Detailed test schedules are contained in the detail specifications. This second edition of IEC 61811-1 cancels and replaces IEC 61811-1 published in 1999, IEC 61811-10 published in 2002, IEC 61811-11 published in 2002, IEC 61811-50 published in 2002, IEC 61811-51 published in 2002, IEC 61811-52 published in 2002, IEC 61811-53 published in 2002, IEC 61811-54 published in 2002, IEC 61811-55 published in 2002, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions:
a) to get one document for telecom relays;
b) update all relevant references.

IEC TS 60255-216-1:2025 covers protection functions with digital inputs and outputs complying with IEC 61850 series and IEC 61869 series, in particular regarding
- subscription to sampled values (SV) streams representing energising inputs instead of analog inputs (see Figure 1);
- subscription to GOOSE (e.g. circuit breaker position, circuit breaker failure);
- publication of GOOSE messages (e.g. trip signals);
- subscription to time synchronisation messages.
On this basis, this document formulates requirements for protection functions with digital inputs and outputs and for the IED hosting them. The document also covers tests related to the functional interoperability and functional requirements of these protection functions, in addition to the general conformance tests required by IEC 61850-10:2012 and test related requirements in IEC TR 61850‑10-3:2022.
