MTL5521 SOLENOID/
ALARM DRIVER
loop-powered, IIC
The MTL5521 is a loop-powered module which enables a device
located in the hazardous area to be controlled from the safe area.
The MTL5521 can drive a certified intrinsically safe low-power load,
as well as non-energy-storing simple apparatus such as an LED.
