6.2.5 MTL4524 - Solenoid Alarm driver
Single channel, switch operated with override, IIC
The MTL4524 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 non-
energy-storing simple apparatus. Short-circuit the Control input terminals to switch the
output on.
A second safe-area input (Override) is provided. When short-circuited, the Override input
will force the output to the off state; when open-circuit it has no effect.
