Product Title: DC 5V 12V 24V 8CH RS485 2.54mm Pin Core Board Modbus Rtu Input and Output Control PLC HMI Remote IO Expanding Board R4PIN08


Packing list: 1 PCS 8ch DC 5-24V 2.54MM Pin RS485 Multifunctional DI-DO Module
(Specific according to the version and quantity you choose)


Description:
1 Power supply1: DC 6-25V(anti-reverse);Power supply2: DC 4-5V(reverse connection prohibited)

2 Working current: 7-13MA;

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)


 

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

For MODBUS RTU command details, see:''R4IOH08 MODBUS RTU Commamd''

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)
