Feature:
1. Using standard Modbus‑RTU protocol, it can be directly adapted to PLC, DCS and various domestic configuration software.
2. RS485 communication signal output interface adopts double protection of overvoltage and overcurrent.
3. Input signal type and communication format can be set by the host computer software, and the power polarity is protected against reverse connection.
4. 4‑channel analog converter, can input 2 channels 0‑20mA, 4‑20mA, 2 channels 0‑5V, 0‑10V four kinds of analog input signals, input analog signal data, and output through isolated RS485 interface.
5. Signal input and the RS485 communication electrical signal are isolated from each other, effectively suppressing various serial mode and common mode interference, ensuring the accuracy of the data, and also ensuring the reliable operation of the module.
