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 system.

1 Power supply1: DC 6-25V(anti-reverse);Power supply2: DC 4-5V(reverse connection prohibited)
 
2 Working current: 6MA
 
3 MODBUS RTU function codes: Write 05/06/15/16, Read 01/02/03
 
4 Five function IO modes can be selected by jumper: 16DI/16DO/8DI-8DO/4DI-12DO/12DI-4DO
 
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*26*3.8mm(Very Small)
15 Weight: 6grams(Very Light)
 

This board is available in pin header and non-pin header versions:

 





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
