Siemens 3RF2950-0GA16 Sirius Safety Relay Module

Siemens 3RF2950-0GA16 is a SIRIUS load-monitoring function element designed to accompany the 3RF29 safety-relay family. It provides a 50 A load-monitoring current range for line voltages of 400 to 600 V and accepts a 24 V AC/DC control input to drive a semiconductor relay or contactor. As a 3RF2 function element, it is intended to be paired with 3RF29 modules in Siemens' SIRIUS safety architectures to monitor current through a protected load and feed a signal to the safety-control chain when thresholds are exceeded. The device is suitable for ambient temperatures up to 40 °C and is used within industrial automation safety circuits that rely on modular safety components. With its 50 A current rating and 24 V control voltage, the 3RF2950-0GA16 extends the monitoring capability of the SIRIUS system for higher-current loads, supporting compact, scalable safety circuitry in control panels and machine installations.
