GS8500-EX Digital Intrinsic Safety Barrier Loop Power

Digital output isolated barriers, control the 12V/35mA and 12V/45mA power supply to hazardous area. This product is suitable for driving IS devices such as solenoid valves, LED and some other low-power loads located in the hazardous area. 


The input and output are each galvanically isolated and allow the control switch to directly connect to either side of 24V DC power supply loop circuit. This galvanic barrier product is loop-powered.
