Power supply2: DC 4-5V(Cannot be reversed)
2 Working current: 6-13MA;
3 MODBUS RTU function codes: Write 05/06/15/16, Read 01/02/03
4 Five function IO modes can be selected by jumper: 8DI/8DO/4DI-4DO/2DI-6DO/6DI-2DO
5 By modifying the 0X00F5/0X00F6 register, the input and output levels (NPN/PNP) can be switched
6 Input mode: Support 3.3V/5V TTL level input, there are two input modes of low level input (default) and high level input
7 Output mode: 5V TTL level, low level (default) / high level output
8 In MODBUS command mode, it can support up to 247 devices in parallel
9 Input port status supports query (default) and automatic reporting
10 BaudRate:1200 2400 4800 9600(default) 19200 38400 57600 115200, None/Odd/Even Parity
11 2.54MM pin header interface, easy to use Dupont wire or breadboard connection
12 Size: 30*25.4*2mm(Very Small and Very Thin)
13 Weight: 3grams(Very Light)
Packing list:
1 PCS 8ch DC 5-24V 2.54MM Pin 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

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)
