Advanced Logic Relay
Camden's CX-33 is an advanced logic relay for door control, available in a prewired power supply cabinet (CX-33PS) with selectable 12V or 24V DC power, color-coded wiring terminals, and a metal enclosure. It offers 15 selectable operating modes via three programming buttons, short-circuit and thermal overload protection, and a 2 Amp UL-listed power supply that can power controls, annunciators, and electrified locking devices.
| Operating voltage | 12/24 Volts, AC/DC |
|---|---|
| Current draw | 105 mA standby, 320 mA max. |
| Inputs | 4 x 'dry' contacts and 1 x 'wet' contact (4.5-120V AC/DC, optically isolated, non-polarity sensitive) |
| Response time | 0.5 seconds |
| Relay output | 3 x Form C (SPDT) |
| Contact rating | 3 amps @ 24 VDC |
| Temperature range | -22°F to 185°F (-30°C to 85°C) |
| Low-voltage wiring | Required |
| Basis | Structured, independently qualified product connection evidence |
| Preparation | Mount the module in a clean, dry location protected from the elements, such as a metal enclosure, operator header or above a false ceiling. Keep the programming buttons and terminal strips accessible while wiring and adjusting it, then secure with the supplied Velcro or sheet-metal screws. Confirm the supplied fastener size: the package list and mounting specification differ. With power off, select the required operating mode and follow that mode diagram for input functions, relay functions and timing; read the instructions and make the required adjustments before applying power. |
| Electrical | Connect 12/24VAC/DC operating power to P1 terminals1 and2, non-polarized, using two circuit conductors; current draw is 105mA standby and 320mA maximum. Four separate dry-input pairs each use two conductors when selected. P1 terminals11/12 accept a powered signal; the conditional conductor count here applies only to a compatible low-voltage signal. The manual gives a 4.5V activation threshold while the terminal drawing labels the input range starting at 5V; verify the actual revision and signal. Each selected P2 dry relay output uses COM with NO or NC (two conductors), or COM with both throws (three). Outputs supply no power. Select the mode and connected equipment before assigning functions; do not add alternative throws together. A regulated supply is recommended for long-duration washroom strike operation. Physical cable runs, type, gauge and shielding remain dependent on equipment and layout. |

| Electrical wiring required | Yes |
