Packing list:
1 PCS 8ch DC 5-24V RS485 Multifunctional DI-DO Module


This module is a multi-function board, you can select various function modes through jumpers.
The jumper uses 0603 0Ω resistor (or wire)

Different Versions of Pin Definitions

For MODBUS RTU command details, see:''R4IOH08 MODBUS RTU Commamd''


By modifying the 0X00F5/0X00F6 register, various input and output levels (NPN/PNP) can be switched

NPN Input & NPN Output(Register 0X00F5=0,0X00F6=0,Default)
PNP Input & NPN Output(Register 0X00F5=1,0X00F6=0)
NPN Input & PNP Output(Register 0X00F5=0,0X00F6=1)
PNP Input & PNP Output(Register 0X00F5=1,0X00F6=1)




Note: The board does not include the ZH1.5mm terminal wire, which needs to be purchased separately
