JY1000-C2-LZ Insulation Monitoring Relay

JY1000-C2-LZ is based on MODBUS protocol of DC insulation monitoring device, is used in on-line monitoring insulation resistance of the DC floating system (two DC system shared one ground). two DC channels are controlled independently, two DC insulation monitoring non-interference in each other. Users can enable or disable the insulation monitoring function of each DC channel and acquire insulation resistance values by RS485 communication.
