The R1.188.1980.0 is an SNE 4004K-C contact expansion relay designed to duplicate the enabling current paths of a basic safety device. It operates on a rated voltage of 24 V AC/DC and supports both single-channel and two-channel control configurations. This relay provides four undelayed normally open (NO) enabling current paths and three undelayed normally closed (NC) signaling paths, conforming to Stop Category 0 according to EN 60204-1. The use of pluggable push-in terminals simplifies wiring and installation. It is ideal for applications requiring the expansion of safety contacts in industrial automation systems, such as for light curtains or other safety sensors.
