The 24Vdc power supply (ref. 4840) cannot be connected directly to the bus, given the characteristics of the DUOX PLUS System, since the power supply and the data go through the same 2 wires.
Therefore, the source ref. 4840 requires this DUOX PLUS Filter, which must be connected directly to the bus with the shortest possible cable distance.
This filter prevents the power supply from disturbing the operation of the rest of the signals that circulate through the system and it will also be the one that allows connecting more sources if the system requires it. The power supply of the DUOX PLUS system is usually carried out by ref. 4825-POWER SUPPLY + FILTER 24Vdc / 2.5A DIN10. However, the ref. 3289 is required for the case in which, due to lack of space, ref. 4825. This filter can only be used with the 24Vdc source (ref. 4840).
IMPORTANT: Do not use with 18Vdc sources.
