GYDCG-UB1K series is a DC-to-ground insulation monitoring module based on the principle of the unbalanced bridge, with monitoring and protection functions in one. It can monitor the positive and negative pole-to-ground insulation resistance of the DC floating system, ranging from 0Ω to 10MΩ; at the same time, it can also detect the DC voltage value, ranging from 0V to 1000V. The user can obtain the measured value through RS485 communication and can set the alarm resistance threshold through the DIP switch or RS485 communication. When the insulation resistance is less than this value, the fault relay will act and the L2 indicator light will be on. At the same time, passive reset and automatic reset can also be selected through the DIP switch configuration bit, and the module stops working at the same time as manual or remote reset.
