Camden CX-EMF-2PS Door Control and Power Supply Cabinet
The Camden CX-EMF-2PS is a microprocessor-controlled relay module paired with integrated 20VDC power delivery, designed to manage single or multi-door access control systems where you need centralized relay logic and power in one cabinet. This unit accepts up to 7 dry contact inputs and provides 5 Form C (SPDT) relay outputs rated at 3 amps each — enough to drive magnetic locks, strike solenoids, request-to-exit buttons, and door sensors across a small- to mid-sized access control deployment.
Overview
The CX-EMF-2PS combines a smart relay module with onboard 20VDC power in a sturdy gray plastic case designed for wall mounting or cabinet integration. Microprocessor control with 3 DIP switch mode selection lets you reprogram logic without swapping hardware — critical when deployment requirements shift mid-project. The unit draws 150mA nominal, 500mA maximum, so it fits cleanly into existing electrical budgets. LED status indicators (power, one status LED, and five relay LEDs) speed troubleshooting during commissioning and ongoing maintenance. Response time of 0.3 seconds meets the sub-second timing demands of fail-safe and fail-secure door logic.
Compatibility
The CX-EMF-2PS works with any access control system that outputs dry relay contacts or low-voltage digital signals — card readers, keypads, biometric controllers, networked access panels, and manual push-buttons all connect via the 7 dry contact inputs. The 5 relay outputs can drive magnetic locks, solenoid strikes, and audible/visual door status signals. The 20VDC supply integrates with strike systems, electrified locks, and auxiliary devices rated for that voltage. Integrators often pair this unit with Camden's CX-EMF-2M (metal cabinet variant with illuminated switches) or CX-EMF-2ABM (two-switch variant) depending on enclosure preference and door-status feedback requirements.
Installation Notes
All wiring connections and adjustments occur on the exterior of the case using removable terminals — no internal rewiring required. Five potentiometers allow adjustment of time delays (1–30 seconds depending on mode) without firmware changes. The unit accepts both 12V and 24V AC/DC input, giving installers flexibility with existing power infrastructure. Electrical life rating of 100,000 operations at rated capacity (3A) or 500,000 at half capacity (1.5A) supports typical access control duty cycles over 5–7 years of continuous service.
