Schmersal PROTECT Safety Relay, 24 V AC/DC - SRB 301MC Series - SRB 301MC-24V
Use this safety relay from Schmersal for emergency stop applications. It's ideal for evaluating signals from magnetic safety switches and has high diagnostic capability. User-friendly LEDs (light-emitting diodes) help with troubleshooting by reporting operating states, such as the supply voltage and internal operating voltage. For enhanced safety, the configurable safety controller has an automatic internal electronic trip that doesn't need to be manually reset. Choose this relay to monitor light curtains as well as safety mats and switches.

Will this safety relay interfere with the function of other electrical components?
This relay produces low levels of electromagnetic interference (EMI), meaning it won't interfere with the functioning of other devices.
How does a safety relay work?
Safety relays feature redundant dual-channel, cross-monitoring logic circuits. These circuits continuously check for and detect faults in the system's safety-circuit components and interconnection wiring.
