IVDM-20 DC Voltage Detection Module IVDM-20 DC Voltage Detection Module User Manual Preface Thank you for choosing INVT IVDM-20 DC voltage detection module. IVDM-20 DC voltage detection module is mainly used in DC-DC bidirectional DC power supply products to detect the input and output voltage and current of the system. It needs to be used with the GD880 series VFD control box. The module transmits the detection signal to the control box through optical fibers, achieving monitoring of system voltage and current. This manual describes the product overview, installation, wiring, and commissioning instructions. Before installing the VFD, read this manual carefully to ensure the proper installation and running with the excellent performance and powerful functions into full play.

Align the installation holes and tighten the screws. Figure 2-2 Installation diagram Note: Ensure that all terminals and fiber optic plugs are installed in place for effective electrical connection. The module is grounded through contact between its exposed metal shell and the assembly board inside the cabinet, so the assembly board must be an exposed metal plate. To ensure the reliable operation of the module and meet the EMC requirements, please tighten the screws to ensure reliable grounding. IVDM-20 DC Voltage Detection Module 2.4 Disassembly instructions Step 1 Disconnect the power supply and disassemble all cables connected to the expansion module. Step 2 Use a Phillips screwdriver to remove the grounding screw of the module. Step 3 Pull the module out to a suitable position. 2.5 User's wiring terminal Figure 2-3 IVDM-20 appearance diagram TXD RXD ON-LINE PRW +15V -15V GND 1A 24V COM +15V -15V GND 1B DC- DC+ Table 2-2 X1 terminal function definition X1 terminal definition DC+ DC- Terminal name Voltage input+ Voltage input- Specifications Input voltage range: 01000VDC Note: The positive and negative DC voltage wiring on the IVDM-20 must match the positive and negative poles of DC-DC output wires.
