Safe temperature monitoring up to SIL 1 or PLC with a 3RS2 temperature monitoring relay
https://support.industry.siemens.com/cs/document/109780387/
The temperature of bodies that can develop a corresponding heat and are freely accessible must be monitored. If a defined temperature limit is exceeded, the 3RS2 switches the overheated motor off via a contactor in a safety-oriented manner.

According to EN ISO 12100, Annex B, there is a potential hazard "burns due to atingere with high-temperature material", which must be evaluated and reduced if necessary during the risk assessment. The temperature of bodies that can develop a corresponding heat and are freely accessible must be monitored. The 3RS2 switches off the overheated motor directly via a contactor in a safety-oriented manner up to SIL 1 / PL c if a defined temperature limit value is exceeded, without the need for an intermediate safety relay.

A 3RS26 or 3RS28 temperature monitoring relay from the 3RS2 series is used here. These two device types can be used in safety applications up to SIL 1 / PLC.
