RGB LED Controller and Remote for Color-Changing Signs, 12-24V

RGB channel letters have red, green and blue LEDs in every module. The controller mixes those three to make any color, and this one does it from a small wireless remote.

With the remote you can:

• Pick a solid color, including white.
• Turn the brightness up or down.
• Run modes that fade smoothly from color to color or jump between colors.

The controller works on 12 V or 24 V DC and sits between the power supply and the RGB LEDs. It is for four-wire common-anode RGB LEDs, the usual type in RGB channel letter modules: one shared positive wire (+) and one wire each for red, green and blue. That is the type we use in our RGB color-changing channel letters, and this controller is a replacement or a spare for the one supplied with them.

The remote is RF (radio), so you do not need to point it at the controller. It works when the controller is hidden inside a raceway, behind a wall or behind the letters.

Before you use the changing modes on a sign that faces the street, check your city's sign code. Many cities restrict flashing, blinking or frequently changing signs, especially near traffic. A slow fade or a single steady color is less likely to be a problem than a fast jump mode, but the rule is set locally.

It is not for single-color signs (use the LED sign dimmer), for five-wire RGBW LEDs, or for addressable pixel LEDs that use a data wire; those need a different controller.

This controller works from its remote only. For on and off from a phone, add our Wi-Fi smart switch on the 12 V side; for full color control from an app, ask us about a Wi-Fi RGB controller.

Count the wires that come out of your RGB letters or modules. Four wires, one marked + or common and three for red, green and blue, means common-anode RGB, which this controller drives. Five wires usually means RGBW, and three wires with a data line means addressable LEDs; neither works with this controller.

Then check the power supply label: 12 V or 24 V DC both work. The controller connects to the power supply on one side and to the LED wires on the other, matching + to + and each color to its color.

If you are replacing the controller that came with our RGB letters, this is the same type. For a large RGB sign from another maker, send us a photo of the old controller label and the wires before you order.
