There are 20 terminals in total. The terminal arrangement on the shell is shown in Figure 1.1. 1.3.2 Terminal description The terminal definitions of WM-IO10 are as follows:
•  GND and VCC are the power input terminals of the module, GND is connected to the negative terminal of the power supply, and VCC is connected to the positive terminal of the power supply;
• INIT is the module’s default communication parameter hardware enable terminal. When this terminal is grounded, the module will
• Parameters are initialized and communication parameters are configurable;
• IN-GND, 485-A, 485-B are isolated RS-485 interface terminals, IN-GND is the isolated ground of the interface,
• 485+ is connected to the A terminal of the RS-485 transceiver, and 485- is connected to the B terminal of the RS-485 transceiver.
• DI0~DI9 are the 4 digital input channel terminals of the module.
• IN-GND is the common ground of the digital input port, which is the same ground as DI0~DI9 of the module.
• It is electrically isolated from IN-GND, and the isolation voltage can reach 2500 VDC. 1.1 Signal indicator light PWR is the power indicator light (red) and working status indicator light RUN (color) 485 communication (TXD) sending indicator light, (RXD) Receive indicator light.

• Certification: CE, FCC
