It also supports RDM (Remote Device Management), which adds two-way communication so you can change the DMX start address or adjust settings remotely.\u003c\/p\u003e\u003ch2\u003eScrew-terminal in and out\u003c\/h2\u003e\u003cp\u003ePluggable green screw terminals take bare wires for DMX in and out, with no soldering or special connectors, which suits retrofits and existing systems where connectors don't match. Daisy-chain several decoders on one DMX line. With more than 32 decoders on a line, add a signal amplifier, and fit a terminal resistor at the end of the line for a stable signal.\u003c\/p\u003e\u003ch2\u003eSet up on the unit\u003c\/h2\u003e\u003cp\u003eA digital display and buttons let you set the DMX start address on the decoder itself. It uses four DMX addresses, with 1, 2 or 4 channel output modes to suit the fittings.\u003c\/p\u003e\u003ch2\u003eOutput\u003c\/h2\u003e\u003cp\u003eThe decoder runs on 12-48V DC. At 12V and 24V each channel gives up to 8A; at 36V and 48V each gives up to 6A, which works out at 96w, 192w, 216w or 288w per channel and up to 1152w in total at 48V. Use it only with constant voltage LED products and a suitable constant voltage power supply, never with constant current fittings.\u003c\/p\u003e\u003ch2\u003eSmooth, flicker-free dimming\u003c\/h2\u003e\u003cp\u003eChoose a PWM frequency from 250Hz to 32kHz; higher settings cut visible flicker for cameras, shops, showrooms and exhibitions. 8-bit or 16-bit dimming gives 256 or 65,536 levels for smoother fades, with logarithmic or linear dimming curves.\u003c\/p\u003e\u003ch2\u003eSelf-test and protection\u003c\/h2\u003e\u003cp\u003eIf the DMX signal is lost, a self-test function starts, with five modes (L-1 to L-5) for commissioning and fault-finding. Overheat, overload, short-circuit and reverse-polarity protection are built in, with automatic recovery. The iron case has a built-in heat sink.\u003c\/p\u003e\u003ch2\u003eWhere to fit it\u003c\/h2\u003e\u003cp\u003eThe case is 175 x 46 x 32mm, so it fits in control cabinets and equipment enclosures. It is rated IP20 for dry indoor locations and works from -30°C to 55°C.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: 4 channel DMX512 and RDM decoder, constant voltage\u003c\/li\u003e\n\u003cli\u003eDMX connections: pluggable screw terminals, in and out\u003c\/li\u003e\n\u003cli\u003eInput: 12-48V DC\u003c\/li\u003e\n\u003cli\u003eOutput: 4 channels, 12-48V DC\u003c\/li\u003e\n\u003cli\u003eOutput current: 8A per channel at 12-24V, 6A per channel at 36-48V\u003c\/li\u003e\n\u003cli\u003eMaximum output: 1152w at 48V\u003c\/li\u003e\n\u003cli\u003eDMX addresses: 4, with 1, 2 or 4 channel modes\u003c\/li\u003e\n\u003cli\u003ePWM frequency: 250Hz to 32kHz\u003c\/li\u003e\n\u003cli\u003eDimming: 8-bit or 16-bit, logarithmic or linear curve\u003c\/li\u003e\n\u003cli\u003eSelf-test: 5 modes\u003c\/li\u003e\n\u003cli\u003eProtection: overheat, overload, short-circuit, reverse polarity\u003c\/li\u003e\n\u003cli\u003eCase: iron, black, 175 x 46 x 32mm\u003c\/li\u003e\n\u003cli\u003eWorking temperature: -30°C to 55°C\u003c\/li\u003e\n\u003cli\u003eIP rating: IP20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LED Supplier","offers":[{"title":"Default Title","offer_id":57691858043253,"sku":"D4-P","price":38.09,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/9772\/5645\/files\/D4-P.png?v=1792893190","url":"https:\/\/ledsupplier.co.uk\/products\/4-channel-dmx512-rdm-led-decoder-screw-terminal-constant-voltage-12-48v","provider":"LED Supplier UK","version":"1.0","type":"link"}
