Typical applications:
1 The dial switch (slave address) is invalid and can only control one module at a time.
2.MODBUS command mode (HEX), you can control a variety of ways: Serial Hyper Terminal Control (need to manually add the CRC), Modbus Poll software control (software automatically add the CRC), PLC or MCU process control
Wiring Diagram:
1 DC 12V control circuit,Wiring diagram below. ''LOAD'' may be camera,LED lights, fans, motors and other DC 12V equipment
2 DC 1-110VAC 85-265V control circuit,Wiring diagram below(Note:If not DC 12V load, need another DC 12V power supply). ''LOAD'' may be LED lights, fans, motors Lights, fluorescent lights, solar water heaters and other DC AC equipment
