Current repeater D5034D

The Switch/Proximity Detector Repeater D5034D is a module suitable for applications requiring SIL 3 level in safety-related systems for high-risk industries. The unit can be connected to switches or proximity detectors, located in Hazardous Area, and repeats the input current to the output in Safe Area. DCS/PLC Digital Input cards compatible with NAMUR devices can detect the status/fault of proximity sensors or switches equipped with end of line resistors, in transparent mode, through the module. - SIL 3/ SC 3 - Input from Zone 0/Div. 1 - Installation in Zone 2/Div. 2 - 2 fully independent channels - Field fault mirroring to PLC NAMUR DI - High Accuracy - Three port isolation, Input/Output/Supply - High Density, two channels per unit Technical Specifications: Supply - Voltage: 24 Vdc nom (18 to 30 Vdc), reverse polarity protected. - Current Consumption: 30 mA @ 24 Vdc with short circuit input, typical. - Power Dissipation: 0.72 W @ 24 Vdc with short circuit input, typical.
