Current repeater X1-NIS-DI-04-S

DIN rail

The Switch/Proximity Detector Repeater X1-NIS-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. 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.SIL 2 / SC 3Installation in Zone 2 / Division 2Loop disconnection to ease maintenance operationsHigh frequency transistor outputField open and short circuit detection (DIP switch programmable)Inverted output available (DIP switch programmable)Line fault transparency to system Digital Input (when fault enabled)Three port isolation, Input/Output/SupplyTechnical Specifications:Power Dissipation: 0.5 W (excluding output dissipation) @ 24 Vdc with short circuit input and closed output, typical.System Supply Voltage: 24 Vdc nom (18 to 30 Vdc).Current Consumption: 20 mA @ 24 Vdc with short circuit input and closed output, typical.System Output Type: MOSFET switches, with series (RL) and parallel (RH-RL) resistances.
