SDC CR4 Door Control Board for Power Supplies

SDC CR4 Door Control Board for Power Supplies, Four Fused SPDT Field Selectable Wet or Dry Outputs, Four Non-Fused SPDT Outputs, 2 Amps at 30VDC, Four Dry Contact Trigger Inputs

Door control relay modules ensure compatibility of access hardware components and simplify system installation and troubleshooting. Modules may be ordered with or without power supplies. Different modules may be specified for one power supply.

SDC’s CR4 series control boards are designed to allow for independent control of up to four separate electified locking devices by distributing the primary DC power supply output into four, individually controlled relay outputs. Each station of CR4 series module accepts a dry, normally open trigger input and provides one fused and one non-fused output. Each output is individually fused and selectable as wet or dry. Closing a switch across the trigger input will release the output for the amount of time that the trigger input is held closed. Output voltage is determined by input voltage. Additionally, LED visual status indicators provide relay activation status.
