The Model H90 servers are connected to the Foxboro Evo Control Network (the control network) on a Foxboro Evo system through dual Ethernet PCIe cards. It can also be simultaneously connected to a generic Ethernet based information network via the two integrated Ethernet ports. Standard security practices should be followed when this is done.

Employing an industrial-grade electromagnetic interference-resistant design, control cables and excitation cables must be wired separately (spacing ≥30cm); grounding requires ≥4mm² copper wire, achieving low-impedance connection (≤1MΩ) through toothed washers to avoid static electricity accumulation (do not wear synthetic material clothing, touch grounded metal to release static electricity before operation); supports ABB 800xA, AC800M DCS systems and third-party SCADA platforms (compliant with IEC 61850, Modbus RTU, CAN, and other protocols); modular stacking expands the number of I/O points, compatible with modules such as PCD231A101 in the same series, and can be mixed for system expansion.

Built-in power system stabilizers (PSS), such as PSS2A/2B, accelerate power integration by synthesizing dual input signals of speed and electrical power to suppress low-frequency oscillations; PSS4B's multi-band compensation technology addresses wide-band damping requirements. Jingdezhen Power Plant has achieved stable operation of its 660MW units across multiple scenarios through PID regulation and adaptive PSS, and supports remote diagnostic tools (such as AVRview) for condition monitoring and parameter adjustment.

The PCD237A101 3BHE028915R0101 central excitation processor supports analog input (±10V/±20mA, accuracy ±0.1%) and digital input/output (isolated design). Communication interfaces include Industrial Ethernet and RS485 (Modbus RTU). It can be integrated into ABB 800xA control systems and AC800M DCS systems, supports IEC 61850 standard configuration, and seamlessly interfaces with third-party SCADA or ABB Ability™ platforms. With its high reliability, interference immunity, and modular design, it is widely used in critical fields such as power, industry, and energy, ensuring safe and stable equipment operation and optimizing system performance. Strict adherence to environmental, wiring, and redundancy configuration requirements is essential during installation to guarantee its efficient operation.

The PCS6000 power system: During peak grid load periods or when energy storage devices are required, the PCS6000 inverts the DC power stored in the battery into AC power, feeding it back to the grid or supplying power to the load. It supports multiple charging and discharging modes, including constant power, constant current, and constant voltage, and can achieve precise power control based on grid dispatch instructions and battery status.

This device belongs to ABB's industrial gas analysis product line and is mainly used for quantitative injection and automated analysis of gas samples. Typical applications include industrial process control (such as air separation and syngas monitoring), environmental monitoring (VOCs detection), and laboratory analysis (gas chromatography with sample injection).
