[Introduction]:ME31-AAAX4220 is a network I/O networking module with 2-way A-type relay output, 2-way analog (0-20mA/4-20mA) input, 4-way dry contact input detection, supports ModbusTCP protocol or ModbusRTU protocol for acquisition and control, and the device can also be used as a simple Modbus gateway (automatically send commands with non-local Modbus addresses through serial ports/network ports).
[Operating voltage]:DC8~28V
[Communication interface]:RJ45, RS485
[Serial port baud rate]]:9600bps (customizable)
