Product Details

This product uses a modular design, achieving dual redundancy for the CPU, power supply, and network modules. It is equipped with multiple input and output modules for digital and analog signals, including AI, A0, DI, D0, and RS485. All modules support hot-swapping, each signal line has protection, and it uses 4-20mA and RS485 signal lines for highly reliable real-time online monitoring of instruments and control cabinets in small stations and oil and water wells. It also supports wireless communication such as ZigBee/LoRa/4G/WIA-PA.
