I.S. SIL2 Line-Fault Transparent Switch/Proximity Repeater

The Switch/Proximity Detector Repeater X1-IS-DI-04 is a module suitable for applications requiring SIL 2 level in safety related systems for high risk industries. The unit can be configured for switches or proximity detectors, located in Hazardous Area. The output port can assume two different impedance values (RL or RH) or it can open completely. The module output repeats the input state according to the following correspondence: low input state -> RL, high input state -> RH. Alternatively, the output can be configured to invert the input state. In both cases, the output can be configured to open if any fault (open or short circuit) occurs at the corresponding input. Four different (RL, RH) sets can be selected through DIP switch to match different system Digital Input card requirements. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.
