Field open and short circuit detection (DIP switch programmable)
Out-of-range fault with programmable thresholds
Inverted output available (DIP switch programmable)
Three port isolation, Input/Output/Supply
The Switch/Proximity Detector Repeater X1-IS-DI-01 is a module suitable for applications requiring SIL 3 level in safety related systems for high risk industries. The unit can be configured for switches or proximity detectors, located in Hazardous Area, and repeats the input state to an open-collector transistor in Safe Area. The selectable fault detection circuit is available for proximity sensors or switches equipped with end-of-line resistors. When selected, the fault drives the common line and forces the output open. Input to output function can be inverted. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.
