8AI4AO 0-20MA/4-20MA/0-5V/0-10V 8 way analog acquisition and 4 way analog output acquisition module MODBUS RS485
MB8AI4AO 8- channel analog quantity acquisition and 4-channel analog output module can collect 8-channel 0-20mA, 4-20mA, 0-5V, 0-10V four analog input signals and 4-channel 0-20mA, 4-20mA 0-5V, 0-10V four kinds of analog signal output; the analog signal data collected by 8AI is output through the isolated RS485 interface, and the data output of 4AO can be controlled through the isolated RS485 interface; the module uses Modbus-RTU communication, which can be directly adapted Equipped with PLC, DCS and various domestic configuration software.
Signal acquisition, signal output, power supply, and RS485 communication electrical signals are isolated from each other, effectively suppressing various types of series mode and common mode interference, ensuring the accuracy of the data, and also ensuring the reliable operation of the module.
two. Features 1. Adopt standard Modbus-RTU protocol. 2. The input signal type of each channel can be set according to your needs . 3. The signal input and output types are designed with no jumper, and can be set by the test software, without opening the shell to set the jumper, which is very convenient for users to use . 4. The module's analog output power supply has a built-in isolated DCDC module, so there is no need to connect another analog output power supply. 5. AO analog output working mode 6. Safety: signal acquisition, signal output, power supply, RS485 communication electrical signals are isolated from each other. 7. Communication protection: RS485 communication signal output interface adopts double protection of overvoltage and overcurrent. 8. Input signal type, output signal type, communication format can be set by software. 9. Power polarity protection and overcurrent protection.
