MTL 4500 Intrinsically Safe Isolators MTL4523L
MTL4523L SOLENOID/ ALARM DRIVER loop-powered with line fault detection, IIC
With the MTL4523L 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 when the output is energised, is signalled by a safe-area solidstate switch which energises 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.
