ATEXDIN rail

SIL2 Switch/Proximity Transistor-Out RepeaterThe Switch/Proximity Detector Repeater X1-NIS-DI-02 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, 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 may also force the output open, if required. 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.FEATURESSIL 2 / SC 3Installation in Zone 2 / Division 2Loop disconnection to ease maintenance operationsHigh frequency transistor outputField open and short circuit detection (software programmable)Inverted output available (software programmable)Three port isolation, Input/Output/SupplySTATUS: ACTIVEProduct lifecycle policy (EN)CHANNELS: 1Technical DataGeneralPower Dissipation0.4 W @ 24 Vdc with short circuit input and 100 mA output current, typical.System SupplyVoltage24 Vdc nom (18 to 30 Vdc).Current Consumption13 mA @ 24 Vdc with short circuit input and closed output, typical.System OutTypeVoltage free SPST optocoupled open-collector transistor.
