R4IOI16 is a 16-channel multi-function RS485 IO core board developed and produced by eletechsup. Through register configuration or jumper selection, it can expand multiple DI-DO modes, and the 2.54MM pin header terminal can be easily embedded in your IO expansion board systeR4IOJ32 is a 32-channel RS485 multi-function IO core board developed and produced by eletechsup. Its IO mode can be set to 32DI/32DO/16DI-16DO/8DI-24DO/24DI-8DO. Input and output can be set to NPN/NPN type. The board is very small and can be easily embedded in your various function boards.
1 Power supply1: DC 6-25V(anti-reverse);Power supply2: DC 4-5V(reverse connection prohibited)
2 Working current: 10MA
3 MODBUS RTU function codes: Write 05/06/15/16, Read 01/02/03
4 Five function IO modes can be selected by jumper: 32DI/32DO/16DI-16DO/8DI-24DO/24DI-8DO
5 By modifying the 0X00F5/0X00F6 register, the input and output levels (NPN/PNP) can be switched
6 By setting the 0X00F3 register, you can restart when communication is abnormal.
7 By setting the 0X00F4 register, you can close all output ports when communication is abnormal.
8 Input mode: Support 3.3V/5V TTL level input, there are two input modes of low level input (default) and high level input
9 Output mode: 5V TTL level, low level (default) / high level output
10 In MODBUS command mode, it can support up to 247 devices in parallel
11 Input port status supports query (default) and automatic reporting
12 Baud-Rate:1200 2400 4800 9600(default) 19200 38400 57600 115200, None/Odd/Even Parity
13 2.54MM pin header interface, easy to use Dupont wire or breadboard connection
14 Size: 51*33.5*3.8mm(Very Small)
15 Weight: 8grams(Very Light)
This module is a multi-function board, you can select various function modes through jumpers.
The jumper uses 0603 0Ω resistor (or wire)
