MTL4521/L – MTL5521 SOLENOID/ ALARM DRIVER
loop-powered, IIC
The MTLx521 and the MTL4521L are loop-powered modules which enable a device located in the hazardous area to be controlled from the safe area. They can all drive a certified intrinsically safe low-power load, as well as non-energy-storing simple apparatus such as an LED.
