Opto-electronic protective devices today frequently have electronic switching outputs and integrated additional functions such as contactor monitoring (EDM) and start/restart interlock. However the requirement for the protective device to transmit the switching signals, not electronically, but rather contact-based to the machine control system often exists.
With the new MSI-RM2 relay module the user is provided with a compact and at the same time cost-effective solution for connecting safety sensors. The relay module, only 17.5 mm wide, has two potential-free make contact circuits with a response time of only 10 ms and LED displays for the switching status.
As its switching behavior is monitored by the EDM function of the safety sensor, an additional electronic monitoring system in the relay module is not required. The MSI‑RM2 is conform to the standard IEC 60204-1.
