Door control relay modules ensure compatibility of access hardware components and simplify system installation and troubleshooting. Fused lock outputs provide individual circuit protection. The isolated relay design allows small gauge cable runs of 20-gauge wire up to 1000 feet from the control device (trigger) to the CR4 module.
The CR4 module operates on 12 or 24VDC and provides control logic and interface for up to (4) doors. Each of the four 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. Closing a switch across the Dry Trigger Input for Stations A, B, C or D will actuate the outputs for the amount of time that the trigger input is held closed. The auxiliary outputs can be used to indicate status or provide logic for multi-door mantraps and complex systems.
