Camden CX-33 Advanced Logic Relay

Camden's CX-33 is a 'state of the art' logic relay designed to support virtually any automatic door application. The CX-33 features 15 operating modes, with sub-modes, and easy programming with large LCD display and push button selection.

Applications: Programmable modes include up to 3 door sequencing, airlocks, lock-out-relay, fire door in stairwells, and for control of automatic operators in restroom applications, with support of illuminated indicator of occupancy status.
Camden's CX-33-PS metal cabinet includes a pre-wired CX-33 advanced logic relay and 2.5 Amp power supply, with the option for a cabinet lock.

Camden Door Controls CX-33 – Frequently Asked Questions

1) Will the Camden CX-33 logic relay run on my 24V door operator power, or do I need a separate supply?
The CX-33 runs on 12 to 30V AC or DC, so it can share the same low-voltage supply feeding most automatic operators or access control gear. Budget 105 mA typical draw, 320 mA at maximum. If you don't have spare capacity on an existing supply, order the CX-33 with the power supply option: that's the CX-33-PS metal cabinet with the relay pre-wired to a 2.5 Amp power supply and a color-coded terminal strip.
2) Can the Camden CX-33 relay switch my maglock or electric strike directly?
Contacts are rated 3 A at 24 VDC across three Form C (SPDT) outputs, which covers a typical maglock or strike drawn at 24 volts. Anything pulling more than 3 amps needs a slave relay or contactor between the CX-33 and the load. Electrical life is 100,000 operations at rated capacity, and because the outputs are Form C you get both normally open and normally closed contacts on each one, so you can fail the device safe or secure without adding hardware.
3) How many door operators can one Camden CX-33 sequence in a vestibule or airlock?
Up to three doors. The CX-33's programmable modes include up to 3 door sequencing plus dedicated airlock modes, and it carries three Form C outputs, one per door, with independent timers: Hold 1, Hold 2 and Hold 3 each run 0-50 seconds, Delay 1 runs 0-15 seconds and Delay 2 runs 0-60 seconds. That's what lets you hold the inner door closed until the outer one has finished its cycle.
4) Should I buy the Camden CX-33 board on its own or the CX-33-PS cabinet version?
Take the bare relay when you already have a powered enclosure with spare 12-30V capacity and room on the backplane. Take the CX-33-PS when the relay is the first thing going in above the door: it's a metal cabinet with the CX-33 pre-wired to a 2.5 Amp power supply and a color-coded wiring terminal, with a cabinet lock available. On a stairwell fire door or a restroom operator install where the relay sits in a public corridor, the locked metal cabinet is the difference between a protected board and an exposed one.
5) How many inputs does the Camden CX-33 accept, and do they have to be dry contacts?
Five inputs total: four dry contact and one wet input that needs a minimum of 4.5V AC or DC. So push plates, card reader relay outputs and motion sensor dry contacts all land on the four dry terminals, and a device that only gives you a voltage output goes to the wet input. Input activation can be delayed 0-10 seconds, and response time is half a second.
6) How much space do I need to mount a Camden CX-33 inside a header or existing enclosure?
The board measures 2 x 6 x 7/8 inches (51 x 152 x 22 mm), so it fits in most operator headers and access control cans. It mounts with two #6 screws or Velcro, which matters if you're dropping it into an enclosure that has no pre-drilled standoffs. The circuit board sits in a clear plastic case, so it can be surface mounted without a separate housing.
7) Can a Camden CX-33 logic relay go in an unheated parking garage or a vestibule that sees outdoor temperatures?
Operating range is -22F to +185F (-30C to +85C), which covers unheated garages, northern vestibules and hot mechanical rooms. The relay itself is a commercial-duty component in a clear plastic case, so in a wet or wash-down location it still needs a suitable enclosure, and the CX-33-PS metal cabinet is the version to specify there.
8) Do I need a laptop or software to program the Camden CX-33?
No software, no laptop, no dip switch chart. The CX-33 is configured at the board with three push buttons and a large blue LED display (one alphanumeric digit plus two 7-segment digits) that shows the mode and timer values as you set them. There are 15 operating modes with sub-modes, so a tech can change a vestibule from simple sequencing to full airlock interlock at the door without pulling the board.
9) What can a Camden CX-33 do besides sequence automatic doors?
Programmed modes cover lock-out relay duty, fire door control in stairwells, and restroom automatic operator control including support for an illuminated occupancy indicator, on top of the up-to-3-door sequencing and airlock modes. For an institutional restroom, that single relay handles the push plate, the operator, the lock and the occupied light rather than stacking three separate timers and relays in the header.
10) Will heavier wire from my door operator fit the Camden CX-33 terminals?
Terminal strips on the CX-33 are oversized specifically to take larger wire gauge or more conductors per terminal, which is what you want when 18/2 operator runs and multiple sensor commons land on the same board. Power circuitry includes filtering and surge protection, worth noting on runs sharing a supply with an operator motor.
