Working Principle:
The module receives a safe 24 V control signal. When the upstream safety relay pulls in, the internal electromechanical relay with mechanically linked contacts closes the 5 NO enable paths and opens the NC feedback. Any contact welding fault is detected through the forced-guided mechanism and reported via the feedback loop.
Application Scenarios:
-
Emergency stop contact multiplication
-
Safety gate lock monitoring expansion
-
Light curtain OSSD output amplification
-
Drive enable circuit isolation
Installation Requirements:
Usage Notes:
-
Never use as primary safety evaluation device
-
Feedback loop must return to safety controller
-
Do not exceed 2.21 W total dissipation
