The Digi-Code DC5120 is a 300 MHz remote control receiver designed to add or restore radio control to gate operators and garage door openers that accept a standard dry-contact input. Engineered for Multi-Code format compatibility, it works with most 300 MHz Multi-Code transmitters to provide reliable, single-button activation for residential and light commercial applications. Powered by 110VAC, the DC5120 installs near the operator and integrates into the control circuit so a matched transmitter can trigger the opener just like a wall button.
Operating at 300 MHz for Multi-Code compatibility, the DC5120 is commonly used as a replacement or upgrade when an existing radio system fails or when a universal receiver is needed to support 300 MHz Multi-Code remotes. Setup typically involves matching the receiver’s internal code switches to the handheld transmitter’s code pattern and wiring the relay output to the opener’s push-button terminals (often labeled COM and NO). For best results, mount the receiver where it can receive a clear signal and ensure proper line-voltage wiring by a qualified installer. This model is suited for operators that accept a momentary contact closure and is an effective solution for integrating Multi-Code 300 MHz remotes into a wide range of garage door and gate control systems.
