ALARM DRIVER
loop-powered, IIC
The MTL5021 enables a device located in the hazardous area to
be controlled by a switch in the safe area. The MTL5021 can drive
a certified intrinsically safe low-power load, as well as non-energy-
storing simple apparatus such as an LED. The unit’s input/output
isolation allows the control switch to be connected into either side of
the 24V dc supply circuit.
