        • Communication Protocol Conversion: If the system is upgraded from earlier serial communication, its Ethernet (EN) interface can be used to connect to an industrial Ethernet network for high-speed data exchange with the DCS.
        • Algorithm Optimization: Upgrade to the latest ProView software version, utilizing "power-off vibration" or "intermittent power supply" algorithms to reduce energy consumption while ensuring emission compliance.
        • Hardware Redundancy Configuration: At critical environmental emission points, it is recommended to implement dual-machine hot standby via the module's communication port to prevent system downtime due to single-module failure.
        • Touchscreen Integration: Upgrade the traditional analog instrument panel to an HMI (Human-Machine Interface) via RS485 or Ethernet connection for on-site visual parameter adjustment.
        • Coal-fired Power Plant Dust Removal: Real-time adjustment of the high-voltage rectifier output to capture fly ash in flue gas is crucial for power plants to meet environmental standards.
        • Cement Plant Kiln Head/Kiln Tail: Handles dust collection under complex operating conditions, supporting multi-zone control to adapt to different flue gas velocities.

        • High Voltage Suppression: Designed specifically for the high-voltage discharge environment of electrostatic precipitators (ESPs), it possesses extremely strong electromagnetic interference (EMI) and surge protection capabilities.
        • Ambient Temperature Limits: Operating temperature is typically required to be between 0°C and 55°C. In high dust concentration conditions, it must be installed in a sealed control cabinet with a protection rating of at least IP54.
        • Dust and Corrosion Protection: The module surface is coated with conformal coating, but exposure to environments containing acidic gases (such as incompletely desulfurized flue gas) or conductive dust should still be avoided.
        • Vibration and Shock: Meets industrial-grade vibration resistance standards, but the installation location should be far away from fans or rapping devices that cause significant mechanical vibration.
