Power supply2: DC 4-5V(Cannot be reversed)
2 Working current: 6-13MA;
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

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)
