D5244
- SIL 2 - SIL 3 Digital Relay Output , Loop Powered
G.M. International ISM0271-5
General Description:
The single and dual channel DIN Rail and Termination Boards Digital Relay Output, models D5244S and D5244D, are loop powered digital output modules enabling a Safe Area loop
voltage signal, to control a device in Hazardous Area, providing 2 port isolation (input/output). Outputs are galvanically isolated.
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 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).
Function:
1 or 2 channels I.S. relay output, provides 2 port isolation (input/output).
