Safety Mat Safety Relay

Safety Mat Safety Relay
Automation safety relay modules provide a high level of fail-safe operation for critical processes and protection. This safety mat and multi-function controllers safety relay offer 2 or 4-wire safety mats/edges. Automatic reset and monitored manual reset are available.

The programmable safety relays support 3 safety output contacts (N/O) and 1 auxiliary output contacts (N/C) or 2NO+1NC+1SO or 2NO(t)+1NC(t).
