Complectation

Spark-safe barrier ISB-1 (Spark-safe discrete inputs) is designed to transmit the discrete signals from elements located in explosion hazard zone to devices located in the explosion-proof zone. Sources of input signals can be sensors, limit switches, remote control panels, intrinsically safe keyboard, etc.
