Mtl5523 - Solenoid Alarm Driver - Eaton Crouse-Hinds MTL5500 Series Instruction Manual

6 .2 .3
Single channel, with line-fault detection, IIC
The MTL5523 interface controls an on/off device in a hazardous area using a volt-free contact
or logic signal in the safe area, and is suitable for driving loads such as solenoids. Line-Fault
Detection (LFD) operates independently of the output state and is signalled by a safe-area,
solid-state switch output which, when a field line is open or short-circuited, becomes de-
energised. Earth-fault detection can be provided by connecting an MTL4220 earth leakage
detector to terminal 3.
