Eaton 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.
