I. Product introduction
      The branch insulation expansion detection module is a The device can be expanded to detect the number of insulated branches.CL6889M01CAs CL6889M01 general detection module extension module, synergistic work to realize the expansion of the number of branches.
      CL6889M01COnly detect the insulation state of the branch, and the running state is affected by CL6889M01 control.
Second, main functions
   1、branch insulation detection: detection up to 32 the positive and negative ground resistance of each branch, and can be adjusted according to the set parent and control parent The branch is detected separately. When detecting the branch, a leakage current sensor needs to be configured on each branch.
   2, communicate with the main module: through CAN< /span>bus andCL6889M01communication, Accept its control and upload branch insulation data.
   3, alarm relay output: when the module detects that the insulation is lowered and the communication of the main module is interrupted, the relay outputs an alarm signal.
  4, indicator status indication: with power, communication, alarm indicator.
