MTL5522 MTL Instruments  Solenoid/ Alarm Driver

          MTL5522 is a loop-powered module which enables a device located in the hazardous area to be controlled from the safe area. TheMTL5522 can drive a certified intrinsically safe low-power load, as well as non-energy-storing simple apparatus such as an LED. The unit'sinput/output isolation allows the control switch to be connected into either side of the 24V dc supply circuit
