Camden CM-RX-DB0 Plug-In Receiver Board 433MHz

The Camden CM-RX-DB0 Plug-In Receiver Board 433MHz is a plug‑in receiver module for Camden's LazerPoint RF system that adds 433 MHz reception to an existing CM-RX receiver. It works with Camden CM-RX control receivers (such as the CM-RX-91 single-relay and CM-RX-92 dual-relay boards) to drive Form C relays rated up to 3 A at 30 V DC, and includes an adjustable hold-open timer and a connection point for the CM-RFCT LED accessory. The CM-RX-DB0 is part of Camden's family of frequency plug‑in daughterboards; the 433 MHz option is listed as CM-RX-DBW with a white antenna in official literature, while other frequencies use blue for 300 MHz, orange for 318 MHz, and red for 390 MHz. Some marketplace listings label the module as CM-RX-DB0 with CM-RX-DBO as the attached daughterboard, reflecting catalog naming variations rather than model numbers. Frequency daughterboards can be inserted into a CM-RX receiver to support up to three wireless frequencies on a single receiver, enabling multi-frequency operation without replacing the base unit, and maintaining compatibility with Camden’s CM-RFCT LED cable tool configurations.
