Product Description

GYDCG-UB1K-ARH is a DC-to-Ground insulation monitoring module based on the principle of the unbalanced bridge, which has monitoring and protection functions in one. It can monitor the insulation resistance value of the positive and negative poles of the DC floating system to the ground, ranging from 1KΩ~10 MΩ; at the same time, it can also detect the DC voltage value, ranging from 100V to 1000V.

The user can obtain the measurement 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 operates and the L2 indicator light is on. At the same time, passive reset and automatic reset can also be selected through the configuration bit of the DIP switch, and the module stops working at the same time as manual or remote reset.
