MTL 5523 Safety Barries Isolaters 

·MTL5523 SOLENOID/ALARM DRIVER with line fault detection, IIC

·With the MTLx523 interface, an on/off device in a hazardous area can be controlled by a volt-free contact or logic 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 safearea solid-state switch which de-energises MTLx523, or energises MTL4523R, 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.

·Output ripple: < 0.5% of maximum output, peak to peak
·Control input
Suitable for switch contacts, an open collector transistor or logic drive.
(Internal contact wetting voltage 12V @ 0.2mA contact closed.Not suitable for voltage control via series diode.)
Output turns on if input switch closed, transistor on or< 1.4V applied across control input
Output turns off if input switch open, transistor off or> 4.5V applied across control input
·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 > 55O and < 4kO.
·Line fault signal characteristics
Maximum off-state voltage: 35V
Maximum off-state leakage current: 10µA
Maximum on-state voltage drop: 2V
Maximum on-state current: 50mA

Red: LFD indication, on when line fault detected
·Maximum current consumption : 100mA at 24V dc

·Power dissipation within unit : 1.2W with typical solenoid valve, output on, 2.0W worst case
