This safety monitoring module relay offers advanced features for secure signal processing. It supports optional short-circuit recognition and includes a manual reset with edge detection in the fail-safe circuit. An automatic reset function is also available. It is designed for processing signals from contact sensors and outputs connected to potentials, such as safety light grids and curtains.
The relay includes three safety contacts for STOP 0 and two adjustable safety contacts for STOP 1 (with an adjustable delay from 1 to 30 seconds). It provides four signaling outputs and operates within a frequency range of 50 Hz to 60 Hz. The operating voltage ranges are 24 VAC (-15% / +10%) and 24 VDC (-15% / +20%), with a ripple voltage of 10%.
The device can withstand vibrations from 10 to 55 Hz with an amplitude of 0.35 mm and shocks up to 30 g for 11 ms.
