Description
Camden CX-12PLUS Door Interface Relay – 12/24 VAC/DC
Flexible door control relay for access control, automatic doors, vestibules and restroom applications.
The Camden CX-12PLUS Door Interface Relay is a versatile 12/24 VAC/DC door control relay designed to simplify the integration of automatic doors with access control systems, electric locking hardware, telephone entry systems, time controls and fire alarm systems. Its compact design combines multiple door-control functions into a single interface module, making the CX-12PLUS well suited for both new installations and system upgrades.
The CX-12PLUS provides eight programmable operating modes, three adjustable time delays of up to 30 seconds, two wet inputs, two dry inputs and two SPDT Form C relay outputs. It also supports bi-directional sequencing of two automatic door operators and basic locked/unlocked restroom control. :contentReference[oaicite:1]{index=1}

Designed for Door Control & Access Control Integration
The Camden CX-12PLUS relay provides a central interface between door activation devices, automatic door operators and related security equipment. Camden specifically designed the CX-12PLUS for interconnection with automatic doors, access control systems, time control systems, telephone entry systems and fire alarm systems. :contentReference[oaicite:2]{index=2}
Typical installations may include an access control credential or push-button input triggering an electric strike or magnetic lock while coordinating activation of an automatic door operator. The relay's wet and dry inputs allow it to interface with a variety of triggering devices, while its dual Form C outputs provide flexibility for controlling connected door equipment.
Bi-Directional Door Sequencing
For vestibule applications, the CX-12PLUS can provide bi-directional sequencing of two automatic door operators. This allows coordinated operation of an exterior and interior door and can simplify installations where doors must operate in a controlled sequence. The CX-12PLUS also includes basic restroom control capability for locked and unlocked operation. :contentReference[oaicite:3]{index=3}
Replacing a Camden CX-12 or CX-22 Relay?
The CX-12PLUS supersedes Camden's earlier CX-12 and CX-22 relay models. Camden states that the release of the CX-12PLUS made both the CX-12 and CX-22 obsolete. The CX-12PLUS combines functions from those earlier products while adding expanded programming capabilities and basic restroom control. :contentReference[oaicite:4]{index=4}
