This gives you a practical alternative to connector-based systems since there’s no soldering or special connectors required. You can simply insert bare conductors directly into the terminals, making it useful for retrofit projects or existing lighting systems where connector compatibility may be an issue.\u003c\/p\u003e\n\u003cp\u003eWith the input and output ports, you can \u003cstrong\u003edaisy-chain multiple decoders\u003c\/strong\u003e. This allows the control signal to pass neatly from one unit to the next while keeping cable management clean, which is always a plus.\u003c\/p\u003e\n\u003cp\u003eStandard DMX installation practices should still be followed to maintain reliable communication throughout the network. That’s why installations that exceed 32 connected decoders, or cable runs that become particularly long, require a \u003cstrong\u003eDMX signal amplifier\u003c\/strong\u003e, and a \u003cstrong\u003eterminal resistor \u003c\/strong\u003eshould be fitted at the end.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eDMX512 and RDM Control with On-Unit Addressing\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eThis decoder supports the standard \u003cstrong\u003eDMX512 \u003c\/strong\u003eprotocol, providing reliable one-way lighting control. In addition, it features an \u003cstrong\u003eRMD (Remote Device Management) \u003c\/strong\u003efunction that enables two-way communication. Simply put, this allows remote configuration of settings, which is convenient when working with a large lighting setup because you don’t have to physically access every decoder.\u003c\/p\u003e\n\u003cp\u003eBut if local configuration is still preferred, you can also find a \u003cstrong\u003edigital numeric display \u003c\/strong\u003ewith onboard buttons on the decoder itself, which you can use to set the DMX start address directly.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the decoder occupies four DMX addresses and allows the output configuration to be selected as \u003cstrong\u003e1, 2 or 4 channels \u003c\/strong\u003edepending on the connected lighting application. This makes it easier to match the controller to different fixture types.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e4 Channel Constant Voltage Output for RGB and RGBW LED\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eBuilt specifically for \u003cstrong\u003econstant voltage \u003c\/strong\u003elighting systems, this decoder should not be used with constant current lighting systems to ensure reliable operation and prevent system failure or damage.\u003c\/p\u003e\n\u003cp\u003eThe four output channels make this decoder compatible with \u003cstrong\u003eRGB and RGBW LED strip \u003c\/strong\u003einstallations, giving you the flexibility to create vibrant colour-changing lighting effects while maintaining consistent performance.\u003c\/p\u003e\n\u003cp\u003eThe unit accepts a \u003cstrong\u003e12V-48V DC input\u003c\/strong\u003e, so it's suitable for different lighting system voltages. The output also varies with the voltage. You get 8A per channel at 12V or 24V, and 6A per channel at 36V or 48V.\u003c\/p\u003e\n\u003cp\u003eThis means that power capacity also scales with the input voltage, providing 96W, 192W, 216W or 288W per channel depending on the selected voltage, with a \u003cstrong\u003emaximum combined output of 1152W at 48V\u003c\/strong\u003e.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eFlicker-Free Dimming with Selectable PWM and 16-Bit Control\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eThe decoder helps produce smoother fades, cleaner transitions, and more refined colour changes for your lighting setup. The option for \u003cstrong\u003ehigher PWM \u003c\/strong\u003efrequencies (ranging from 250Hz to 32kHz) also helps minimise visible flicker, which is very useful in spaces focused on photography and video recording, as the lighting appears more stable on camera. \u003c\/p\u003e\n\u003cp\u003eFor even greater precision, the decoder allows you to choose between \u003cstrong\u003e8-bit (256 levels) \u003c\/strong\u003eand \u003cstrong\u003e16-bit (65,536 levels) \u003c\/strong\u003egrey scale control. The higher grey scale provides much finer dimming resolution and smoother colour transitions, particularly at lower brightness levels. You can also select either a \u003cstrong\u003elogarithmic (gamma 1.6) \u003c\/strong\u003eor \u003cstrong\u003elinear (gamma 1.0) \u003c\/strong\u003edimming curve to better match the desired visual effect.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSelf-Test Mode and Full Built-In Protection\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003ePractical features like the \u003cstrong\u003eself-test mode \u003c\/strong\u003eare useful functions that automatically become available when the incoming DMX signal is interrupted. If that happens, the \u003cstrong\u003eL-1 to L-5 \u003c\/strong\u003etest modes light the four output channels individually or simultaneously, making it easy to identify connection issues. This feature does not interfere with normal lighting controls.\u003c\/p\u003e\n\u003cp\u003eThe decoder also comes with \u003cstrong\u003emultiple built-in electrical protections \u003c\/strong\u003eagainst overheating, overload, short circuit, and reverse polarity. It also includes automatic recovery once the fault is resolved.\u003c\/p\u003e\n\u003cp\u003eHousing all these protection systems is a durable \u003cstrong\u003eiron-shell casing \u003c\/strong\u003ewith a quick heat sink that dissipates heat efficiently, maintaining steady performance at higher output, even under demanding operating conditions and during extended use.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eCompact Iron-Shell Design with Long-Term Reliability\u003c\/h2\u003e\n\u003cp\u003eHigh performance does not mean bulky components, especially since this decoder measures just \u003cstrong\u003e178 x 50 x 38mm\u003c\/strong\u003e. The slim build means you can position the unit even in tight areas without worrying about it taking up valuable space or being too bulky. It also comes with an \u003cstrong\u003eIP20 protection rating\u003c\/strong\u003e, making it ideal for dry indoor installations, and is designed to operate in temperatures ranging from \u003cstrong\u003e-30°C to +55°C\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eWhen it comes to reliability, the decoder is manufactured to meet recognised \u003cstrong\u003eCE, RoHS, and FCC certification \u003c\/strong\u003erequirements, including compliance with EN IEC 55015, EN IEC 61547, EN 61347-1\/-2 and EN 62493. As a complete package, every decoder comes with a \u003cstrong\u003e5-year warranty\u003c\/strong\u003e and more than \u003cstrong\u003e14,000 five-star reviews \u003c\/strong\u003eacross platforms such as Google, Trustpilot, and Reviews.io.\u003c\/p\u003e","brand":"Simple Lighting LTD","offers":[{"title":"Default Title","offer_id":57666331443544,"sku":"D4-P","price":36.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0976\/7020\/1688\/files\/D4-P.png?v=1783513518","url":"https:\/\/www.simplelighting.co.uk\/products\/4-channel-dmx512-rdm-led-decoder-screw-terminal-ports","provider":"Simple Lighting LTD","version":"1.0","type":"link"}
