4AI4AO module is a module with 4 channels analog input and 4 channels analog output, this module can be used to collect 4 channels 0 ~ 20mA, 4 ~ 20mA, 0 ~ 10V analog signal, output 4 channels 4 ~ 20mA analog signal.
The module uses the standard Modbus RTU communication, adapts many kinds of software, PLC, DCS and so on. The module power supply, RS485 communication electrical signals isolated from each other, effectively inhibit the series mode and common mode interference.
4 channels analog input / output (DC 0-20mA / 4-20mA), the use of independent 12-bit industrial AD / DA chip, to meet the industrial monitoring and control requirements.
Communication format can be set by software, long press the button behind the module for 3 seconds, the module can be restored to factory settings.
Using RS485 MODBUS RTU standard communication, configuration software, PLC and industrial touch screen can form network.
Signal control, power supply, RS485 communication electrical signals isolated from each other.
Communication circuit with lightning protection, anti-interference, power polarity protection.
Communication circuit lightning protection, anti interference.
RS485 communication signal output interface with over-voltage over-current double protection
Signal acquisition and control can be widely used in industrial field devices.
Communication format can be set by software.
