O. Safety 1 N.C. Auxiliary nonsafety Description The Allen-Bradley Guardmaster 120V AC interface box consists of a NEMA 4 rated lockable metal enclosure, a DIN mount 3amp, 24V DC power supply and either a single or dual 22.5mm safety relay(s). The single safety relay module provides 3 N.O. safety and one N.C. auxiliary (nonsafety) “potential free” relay outputs. The dual safety relay configuration allows for two pairs of safety light curtains to independently control one or two machines. The safety relay(s) can be configured for manual reset or automatic reset. The resetting function can be through the key switch mounted on the front cover of the interface box. Pre punched holes located on the bottom of the enclosure allow for easy wiring of the system.
