Wiring Diagram:
Ii : 1-Channel 4-20MA Current Input
Vi : 1-Channel 0-10V Voltage Input
Di1/Di2 : 2-Channel PNP Digital Input
Relay: 20-Channels 10A Relay Output
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
