1 Ch, Digital Relay Output Module


The dual channel DIN Rail Digital Relay Output, D1044D, is a digital output module enabling a Safe Area contact, logic level or drive signal, to control a device in Hazardous Area, providing 3 port isolation (input/output/supply). Outputs are galvanically isolated and inputs are depolarized to ease wiring operations. Typical applications include switching of Hazardous Area circuits, changing of polarities and sounder tones, calibrating of strain gauge bridges, resetting of field devices, testing of fire detectors. Each input channel can be isolated from supply (Bus Powered mode) or externally connected (by wiring) to supply (Loop Powered mode, where the safety PLC directly supplies the module and its input channel). Each output channel provides a SPDT relay, with two contacts defined NO (Normally Open) and NC (Normally Close) when the output relay is de-energized. Considering each channel NE (Normally Energized), the output relay is energized, so that NO contact is closed (useful for NE loads or Hazardous Area circuits) and NC contact is open (useful for ND loads or Hazardous Area circuits). The safe state is reached when the channel and the output relay are de-energized, so that NO contact is open (de-energizing loads or Hazardous Area circuits) and NC contact is closed (energizing loads or Hazardous Area circuits).
