2 ch. Loop Powered Fire / Smoke Detector Interface


The D1022D is a loop-powered single or 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.
• Input/Output isolation.
• EMC Compatibility to EN61000-6-2, EN61000-6-4.
• High Reliability, SMD components.
• High Density, two channels per unit.
• Simplified installation using standard DIN Rail and plug-in terminal blocks.
• 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier.
