SCM1 Series Distributed Insulation Detection Unit

Distributed small current detection system SCM1 is a kind of equipment for on-line detection of the mother and the control branch. A single module can detect the insulation status of the 30-way branch, and can detect the control, the mother, the bus, and the control. The bus is connected to the bus, the bus is negatively connected, and the voltage is internally connected. The serial communication port uses the RS485 digital port to communicate with the host computer (LCD). The sampling loop is isolated from the RS485 optocoupler. Therefore, the module is self-contained. Integral, fast sampling speed, high reliability, easy installation and maintenance

Back
