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
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
