This device is a DC signal isolator with standard signal isolation and power output distribution function. Using principles of linear optocoupler isolation, the input DC voltage or current signal can output DC voltage or current signal through the electrical isolation. This device is treble isolation, its input, output and auxiliary power isolated from each other. Especially suitable to be used together with the sensor/transducer and instrument which needs electrically isolate. Can widely used in computer, PLC measurement and control system and a variety of automatic control systems.
