MTL5523
SOLENOID/ALARM DRIVER
with line fault detection, IIC
With the MTL5523 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 de-energises MTL5523, if a field line is
open or short–circuited. Earth fault detection can be provided by
connecting an MTL4220 earth leakage detector to terminal 3.

Control input
Suitable for switch contacts, an open collector transistor or logic
drive
Output turns on if input switch closed, transistor on or
< 1.4V applied across terminals 11 & 12
Output turns off if input switch open, transistor off or
> 4.5V applied across terminals 11 & 12
Response time
Output within 10% of final value within 100ms
Line fault detection (LFD)
Open or short circuit in field cabling de-energises solid state
line-fault signal.
LFD transistor is switched on, provided that the field circuit
impedance is > 55Ω and < 6k5Ω.
