0-10V lighting control
Encyclopedia : 0 : 01 : 010 : 0-10V lighting control
0-10V is one of the earliest and simplest electronic lighting control signalling systems; simply put, it is a DC voltage that varies between zero and ten volts. The controlled lighting should scale its output accordingly so at the highest voltage, the controlled light should be at 100% of its potential output; at 5V, it should be at 50% output; and at 0V should at 0% output (or in other words, “off”).
With the theatrical lights it has been almost completely replaced by DMX and with dimmable Fluorescent lamps (where it operates instead at 1-10v where 1v is minimum and 0v is off)is starting to be replaced by DSI and DALI.
Advantages
- Its simple nature makes it straight forward to understand, implement and diagnose while its low voltage means it typically runs along relatively thin cables.
Disadvantages
- It requires one wire per control channel so a sophisticated system could have hundreds of wires, thereby making diagnoses of problems difficult.
- Over a long cable the voltage drop could mean the signal received by the controlled light is not at the same level as the signal that was sent.
