This is an 8-channel multi-function RS485 IO module designed and produced by eletechsup, it uses 141R Spring Terminal Blocks. It has multiple IO input and output functions, and the wiring is quick and easy.

1 Power supply: DC 6-25V(anti-reverse);

2 Working current: 8-12MA;

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 141R Spring Terminal Blocks(
Strip Length 11mm)

12 Size: 44*30*17mm

13 Weight: 12.5grams

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

How to use spring terminal blocks:

Insert: Insert the wire (Strip Length: >11mm) into the wiring hole. If the wire is too soft to be inserted, gently push the orange pick and then insert it.

Pull out: Push the orange pick to pull out the wire

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)
