​​​​​​​​​​​ SPD4DC (U=7-60VDC)​​

​​ We present to your attention a four-channel DMX splitter on a DIN rail VJLight SPD-4i with double galvanic isolation and indicators (power and incoming DMX signal). This splitter is designed to amplify the DMX signal and branch one control signal line into four. It is an excellent installation solution for clubs, restaurants, private homes, apartments, and even renters. It has one detachable three-pin DMX input and four detachable three-pin outputs with galvanic isolation, both in terms of power and signal of each channel. The SPD-4i is made in a shock-resistant plastic case and is designed for installation directly in the electrical panel on a DIN rail. The DMX splitter is connected to a network of variable or constant voltage VAC 85-264/VDC 70-350. It is possible to supply with a power supply voltage of 7-60 VDC (including from an unstabilized IP). Each DMX input and output is powered by its own voltage stabilizer (galvanically isolated), DMX signal amplifiers of each channel retransmit the signal through galvanic isolation, which in case of failure of lighting devices or DMX line malfunction provides protection for devices connected to other signal control lines. In the SPD-4i, a more advanced, high-speed (up to 1024 DMX channels at the output) and reliable method is used as galvanic isolation of the DMX signal, which is devoid of such drawbacks of optocouplers as their degradation during operation. VJLight SPD-4i has automatic protection against short circuit, overload, and overvoltage with self-recovery.​​
