D1022D

Loop Powered Current Repeater DIN-Rail

The D1022D is a loop-powered dual channel isolated current repeater. It can be used to interface transmitter, to drive I/P converter, fire and smoke detectors or similar switched resistor systems, located in Hazardous Area, requiring a wide output current range (from 1 to 40 mA) to operate properly. When drive I/P converter, positioner, display a current source is connected to the input terminals, while interfacing transmitter or fire and smoke detector a voltage source with current readback can be connected. The transmitter current is sinked from the input terminals operating as a transparent interface. For fire and smoke detector, the triggering of a detector causes a corresponding change in the Safe Area circuit current. A field open circuit reflects a high impedance to the control device circuit. The unit has reverse input polarity protection and ≤ 1 % accuracy.

• Output to Zone 0 (Zone 20), Division 1, installation in Zone 2, Division 2.
• Wide operating current range from 1 to 40 mA.
• Field open circuit detection.
