Current repeater X1-IS-DI-01-S

ATEXSIL 3

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.SIL 3 / 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 (DIP switch programmable)Out-of-range fault with programmable thresholdsInverted output available (DIP switch programmable)Three port isolation, Input/Output/SupplyStatus: ACTIVEChannels: 1Technical Data:GeneralPower Dissipation0.46 W @ 24 Vdc with short circuit input and 100 mA output current, typical.System SupplyVoltage24 Vdc nom (18 to 30 Vdc).Current Consumption15 mA @ 24 Vdc with short circuit input and closed output, typical.System OutTypeVoltage free SPST optocoupled open-collector transistor.
