SICK RLY3-EMSS300 Sensor
SICK RLY3-EMSS300 safety relay, part 1099973. ReLy family evaluation of safety sensors with guided-contact outputs.
Overview
The SICK RLY3-EMSS300 (part number 1099973) is a safety relay of the ReLy family. It evaluates safety sensor signals, such as emergency stops and guard switches, and switches safe outputs for the machine control, supporting dependable safety functions in industrial machinery.
How It Works
Safety input circuits are monitored for integrity; with the inputs activated and healthy, the guided-contact outputs enable machine operation. Sensor tripping or internal faults open the outputs, ensuring the hazardous motion stops safely.
