SIRIUS safety relays are the key elements of a consistent and cost-effective safety chain. Be it EMERGENCY-STOP disconnection, protective door monitoring or the protection of presses or punches – with SIRIUS safety relays every safety application can be implemented to optimum effect in terms of engineering and price.

SIRIUS safety relays provide numerous safety-related functions:

Monitoring the safety functions of sensors
Monitoring the sensor leads
Monitoring the correct operation of the safety relay
Monitoring actuators for standstill
Safety-related disconnection when dangers arise

Depending on the version of the device, SIRIUS safety relays satisfy the most stringent requirements (PL e) of EN ISO 13849-1 and achieve the highest Safety Integrity Level (SIL 3) according to IEC 61508.
