SCR safety relays are used to analyze safety signals such as those generated by position switches, safety switches, safety interlocks, pull cord switches, safety sensors or 2-hand controllers. Two NC contacts are required as signal contacts for fence monitoring. Virtually all BERNSTEIN switches have these contacts.
