The MTLx525 enables an on/off device in a hazardous area to be
controlled by a volt-free contact or logic signal in the safe area. It can
drive loads such as solenoids, alarms, LEDs and other low power
devices that are certified as intrinsically safe or are classified as nonenergy storing simple apparatus.
The MTL4525 allows a second safe-area switch or logic signal to be
connected that enables the output to be disabled to permit, for example,
a safety system to override a control signal.
