6.2.4 MTL5523V/MTL5523VL - Solenoid Alarm driver
Single channel, voltage controlled with line-fault detection, IIC
With the MTL5523V or MTL5523VL interface, an on/off device in a hazardous area can be
controlled by a voltage signal in the safe area. It is suitable for driving loads such as solenoids.
Line fault detection (LFD), which operates irrespective of the output state, is signalled by a safe-
area, solid-state switch which energises if a field line is open or short–circuited.
The VL version has a lower current capability to suit alternative load requirements - see datasheet.
