4 Channel Remote Control for RU-ASX4D and RU-ASX4DR-Black

Ideal Use Cases

The RDL DB-RC4M is a four-channel remote control designed for direct integration with RDL RU-ASX4D and RU-ASX4DR source selectors. It provides an accessible control point wherever users need to choose among four connected sources. A dedicated momentary pushbutton is provided for every channel, and four green LEDs identify the selected channel. The unit supports either a single control location or a distributed arrangement with as many as ten remote locations. This makes it suitable for systems that require the same source-selection controls at multiple operating positions.

Why Choose This Model

Each source has its own selection button, giving the operator a direct one-button method for changing channels. Green LED indication provides immediate confirmation of the active selection. During adjustment, the display remains bright for clear visibility; after the adjustment, it dims. This behavior combines clear operating feedback with a less prominent display when no changes are being made.

The DB-RC4M also offers a professional aesthetic appearance and is identified as a companion to other RDL remote controls. Stainless steel, black, and white versions are available, allowing the control interface to coordinate with different installations. This listing is for the black model.

Installation and Integration

The DB-RC4M mounts in a standard US electrical box or in compatible RDL WB- and SMB-series boxes. Its compact faceplate measures 4.11 inches high by 1.31 inches wide, with a depth of 0.98 inch. Metric dimensions are 10.44 by 3.33 by 2.49 centimeters. A detachable terminal block simplifies access to the wiring connections.

Remote wiring can use six conductors or UTP cable, including CAT5 or CAT6. The control interfaces directly with the RDL RU-ASX4D and RU-ASX4DR. Its power requirement is ground-referenced 24 Vdc at 30 mA. The recommended power supplies listed in the source information are the RDL PS-24AS for the USA and PS-24AX for international use. These defined mounting, cabling, connection, and power requirements provide installers with concrete system-planning information before deployment.

Performance Highlights

Four momentary pushbuttons provide one selector for each channel, while four green LEDs indicate which channel is selected. The remote-control architecture accommodates up to ten locations, supporting both straightforward single-panel systems and installations with several operating points. Six-conductor or CAT5/CAT6 UTP wiring gives installers multiple stated cabling options.

The specified ambient operating range is 0 degrees C to 55 degrees C. The unit has a WEEE weight of 0.22 pounds and a shipping weight of 0.375 pounds. It ships in a cardboard box measuring 3.625 by 4.625 by 2.125 inches.

What Makes It Different

The DB-RC4M combines direct four-source selection, channel-status indication, and multi-location control in a narrow wall-mounted format. Instead of sharing a single selector among all channels, it assigns one momentary button to each source. The corresponding green indicators keep the active channel visible at the control surface.

Its ability to support up to ten remote locations is a defining capability for systems requiring repeated source controls. Direct compatibility with the RU-ASX4D and RU-ASX4DR establishes its intended integration path, while standard electrical-box mounting and support for RDL WB- or SMB-series boxes offer documented installation choices. The availability of stainless steel, black, and white finishes further distinguishes the control as part of a coordinated RDL remote-control installation.

Final Assessment

The RDL DB-RC4M is a focused control interface for selecting four sources through an RU-ASX4D or RU-ASX4DR system. Its four dedicated pushbuttons, four green channel LEDs, support for up to ten control locations, detachable terminal block, and CAT5/CAT6-compatible remote wiring address the essential operating and installation requirements of a distributed source-selection system. With compact dimensions, standard-box mounting, defined 24 Vdc power requirements, and a black professional-format panel, it provides a clearly specified solution for remote four-channel selection.
