Isolating switch-coupler TS500-Ex can be used for monitoring and controlling digital signals out of the hazardous area.
The intrinsically safe input is suitable for switching contact, proximity switch acc. Namur DIN EN 60947-5-6), or passive electronic outputs of other devices.
The devices must be installed out of the Ex-area because only the input is intrinsically safe.
The Operating mode between input and output can be selected by DIP switches at the front panel (open-circuit or close circuit working).
The frontside LEDs indicate the activated output.
Line fault detection:
When operating with Namur proximity switches the controlling function for broken line and shorted line can be activated by DIP switch.
In case of an error, the output changes to inactive and the LED indicators are flashing.
For connection with switching contacts external resistors are necessary.
