The type IKMb 122 Ex signal processing units connect to intrinsically safe EGE two-wire sensors for hazardous gas and dust atmospheres. They feature a space-saving, 22mm wide DIN rail housing and are installed outside the hazardous area.
Green, yellow, and red LEDs on the front side indicate the operating status and signal alarms, if the integrated cable breakage detection or the short-circuit monitoring is triggered. The output can be set as normally closed or normally open.
