DMX512 Decoder 4 Channel RGBW DIN Rail with RJ45

The FEL-CD267 is the 4-channel DMX decoder for the DIN rail: RGBW output — red, green, blue and white on four separate channels at 6 amps each — with 4096 grey levels per channel and the DMX512/1990 line landing on the terminal block. It is the decoder for the large-scale panels that run the RGBW strips and fittings, and the electrical set is identical to the 5-channel RGBWW decoder beside it in the range — the white channels merged into one.

The four channels

The output is RGBW — the RGB channels carry the colour mix, and the white channel carries the white independently at 6 amps. The output is constant-voltage PWM, so the strip and the fittings on the far side run at the voltage the supply delivers. The 4-channel set is the one the RGBW strips and the colour-plus-white fittings are wired for, and the decode keeps the four channels on four consecutive DMX addresses.

4096 grey levels per channel

Each channel decodes at 4096 levels, which is the resolution the smooth dimming needs: the fades run without the stepping the 8-bit decoders show at the low end, and the slow scene changes read clean on camera. The Highlights call it smooth, soft dimming, and the 4096-level decode is the number behind it.

DIN rail, terminal block, master or slave

The mounting is the DIN rail that clicks into the distribution board — the install the large-scale projects run, with the decoders lined in the panel per zone. The DMX512/1990 line lands on the terminal block, and the controller runs as master or slave on the line: master for the standalone setups, slave for the desks and the main controllers. The four channels take four consecutive DMX addresses.

Working envelope

Working temperature spans -20°C to +55°C, which covers the plant rooms, the ceiling voids and the distribution boards the decoders actually live in. The body is L111×W46×H66mm at 135g — the same envelope as the CD264 and the CD266, so a mixed family panel keeps a single rail layout. The decoder is the panel-mounted unit the DIN rail carries without a shelf or a bracket.

Where it gets used

The large-scale architectural installs, where the decoders line up in the distribution boards and the RGBW strips run the colour and the white from one decoder per zone. Hotels and façades, where the dual-white fittings dim and shift on the 4096-level decode. Stage and studio rigs, where the CV strips decode as slave to the desk. And the retail and display installations, where the 4096-level decode drives the slow, camera-visible fades the display lighting runs.

Planning the panel

Work the load per decoder against the strip: at 24V the decoder carries 576 watts before the ceiling, and the 12V builds carry 288. Leave headroom below the 6-amp rating on each channel rather than loading to it. Size the PSU for the connected load plus margin, land the DMX in and out on the terminal block, and give each decoder its start address. Split the large façades across several decoders per zone; the daisy-chain carries the line between them.

Choosing the decoder in the range

The DMX decoder family splits by channel count and connection: the CD267 is this 4-channel RGBW decoder on the DIN rail; the CD268 is the 5-channel RGBWW for the dual-white fittings; the CD269 series runs 24 and 32 channels for the multi-zone panels; the CD265 is the single-channel decoder at 10 amps for the monochromatic zones; and the CD206-4 is the standalone RGBW decoder with the XLR-3, RJ45 and terminal connections for the rigs. The choice is the channel count the zone needs — the 4096-level decode, the DIN rail and the master-or-slave logic are the same across the range.

Why do buyers pick the FEL-CD267 over the alternatives? Here is what we hear from customers:

DIN rail for the large-scale installs. The decoders line up in the distribution board instead of scattering across the ceiling void — the panel the electrician wires is the panel the AV team patches, and both sides find the channels where they left them.

RGBW: the four channels the strips are wired for. Red, green, blue and white at 6 amps each — the set the RGBW strips and the colour-plus-white fittings run, without the fifth channel the dual-white builds need.

4096 grey levels per channel. The fades run without the stepping the 8-bit decoders show at the low end — the slow scene changes read clean on camera, and the low-end dimming is where the cheap decoders fail.

Terminal block for the panels without structured cabling. The DMX lands directly on the block — the simpler wiring for the installs that do not run the RJ45, with the daisy-chain continuing from the same block.

Master or slave. The decoder runs standalone as master or joins the desk as slave — the small installs and the big rigs run the same hardware.

The FEL-CD267 is the decoder for the large-scale RGBW installs: the DIN-rail fitting that sits in the distribution board and drives the colour and the white from the DMX line.

Architectural and façade lighting. The decoders line the distribution boards, the terminal blocks land the DMX per zone, and the RGBW strips run the colour and the white from one decoder per zone.

Hotels and hospitality. The colour-plus-white fittings dim and shift on the 4096-level decode, the scene changes read clean on camera, and the DIN rail keeps the decoders in the panel the staff can reach.

Stage and studio rigs. The CV strips decode as slave to the desk, the four RGBW channels cover the colour and the white separately, and the master mode runs the small rigs without a console.

Retail and display installations. The 4096-level decode drives the slow, camera-visible fades the display lighting runs, and the decoders scale across the floors on the rail.

Distribution-board installs. The decoders line up in the panel the electrician wires, the terminal block lands the line where the structured cabling stops, and the panel layout is the documentation the next contractor reads.
