MTL 5500 Intrinsically Safe Isolators MTL5523
MTL4523/R – 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.

SPECIFICATION

Number of channels
One
Location of load
Zone 0, IIC, T4–6 hazardous area if suitably certified
Div. 1, Group A, hazardous location
Hazardous-area output
Minimum output voltage: 13.6V at 48mA
Maximum output voltage: 24V from 180Ω
Maximum off-state output voltage: 4V from 180Ω
Current limit: 48mA minimum
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 > 55Ω and < 4kΩ.
* These conditions are reversed for the MTL4523R. This is to permit parallel
connection of alarms between modules to provide a group alarm output.
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
LED indicators
Green: power indication
Yellow: output status, on when output active
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
Safety description
Uo=25V Io=147mA Po= 0.92W Um = 253V rms or dc
