Current repeater X1-IS-DI-02-S

SIL 2for hazardous areas

The Switch/Proximity Detector Repeater X1-IS-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, 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 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.SIL 2 / SC 3Input from Zone 0 / Division 1Installation 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/SupplyTechnical Specifications:Power Dissipation: 0.4 W @ 24 Vdc with short circuit input and 100 mA output current, typical.System Supply Voltage: 24 Vdc nom (18 to 30 Vdc).Current Consumption: 13 mA @ 24 Vdc with short circuit input and closed output, typical.System Output Type: Voltage free SPST optocoupled open-collector transistor.
