The CR4 four station control relay module operates on 12V or 24V DC and provides control of four (4) stations. Each CR4 station accepts a Dry (NO) trigger input and provides one (1) Fused 2 Amp SPDT Output (jumper selectable Wet or Dry) and one (1) Non-fused Dry (2 Amp) SPDT output (jumper selectable Wet or Dry). Closing a switch across the Dry Trigger Input for Station A, B, C or D will release the output for the amount of time that the trigger input is held closed. The CR4 module can be used to indicate status or implement multiple door interlocks.
