4 Functions and features
The safety relay is a redundant system and suited for use as:
• Safety relay for fail-safe sensors/switches with 2 PNP outputs (e�g� GM701S)�
• Safety relay for clocked fail-safe sensors (e�g� GM504S)
• Two-hand control to EN 574, type IIIC, with electronic sensors/switches
• Two-hand control to EN 574, type IIIC with mechanical switches / safety relay
for mechanical switches or 2-channel fail-safe sensors/switches (e�g� ESPE to
EN 61496-1) with contact output with simultaneity monitoring
• Safety relay for mechanical switches or 2-channel fail-safe sensors/switches
(e�g� non-contact safety devices EN 61496-1) with contact output and without
simultaneity monitoring (indefinite simultaneity)
The safe state is when the output contacts (13-14 or 23-24) are open�
ifm electronic gmbh assumes no liability for the use of units made by
external manufacturers�
Suitability of the product for a certain application cannot be assured and
must be ensured by the user�
The safety relay conforms to the category 4 according to EN 954-1 (valid until
31 December 2011), Performance Level e according to EN ISO 13849-1: 2008
as well as to the requirements SIL 3 to IEC 61508 and the classification type IIIC
according to EN 574�
