I. Product Overview
The GE IS210MACCH2AGG is a core main control board in the Mark VIe series control system, specifically designed for the precise control and status management of industrial-grade steam turbines, gas turbines, and combined cycle units. As the "computational core" of the Mark VIe system, it undertakes key responsibilities including control logic execution, real-time data processing, and equipment collaborative scheduling, serving as a core hardware carrier to ensure the safe, efficient, and stable operation of large-scale power equipment.
In terms of physical form, this board adopts a standard 6U VME industrial board design with a compact overall size (approximately 160mm in height, 233mm in width, and 25mm in thickness). It has no independent operation panel and achieves high-speed data interaction with other modules through the system backplane. The component layout on the board surface complies with industrial-grade anti-interference standards; key chips are protected by metal shields, and the pin soldering process meets military-grade reliability requirements. It can adapt to long-term high-load industrial operating environments and is widely used in fields such as power generation, petrochemicals, and metallurgy, where extremely high requirements are placed on equipment control accuracy and stability.

III. Core Functional Features
1. High-Performance Control Logic Calculation
As a main control board, the IS210MACCH2AGG is equipped with a 32-bit high-performance embedded processor (with a maximum main frequency of 800MHz), boasting strong real-time computing capabilities and supporting the parallel execution of up to 1,000 complex control logic instructions. Its built-in dedicated control algorithm library covers core functions such as turbine start-stop control, speed closed-loop regulation, load distribution, and Emergency Trip System (ETS) logic. It can automatically switch control strategies according to unit operating conditions (e.g., cold start, hot start, normal operation, shutdown maintenance), ensuring the control accuracy of the unit throughout its life cycle (speed control error ≤ ±0.1% of rated speed, load regulation response time ≤ 100ms).
2. Multi-Dimensional Data Acquisition and Processing
The board integrates 16 analog input (AI) channels, 16 digital input (DI) channels, 8 analog output (AO) channels, and 8 digital output (DO) channels, which can be directly connected to on-site equipment such as temperature sensors (thermocouples/RTDs), pressure transmitters, vibration sensors, and valve actuators. It supports the acquisition of standard industrial signals such as 4-20mA and 0-10V, with an analog input accuracy of ±0.05% FS and a digital input response time ≤ 1ms. It can real-time capture key operating parameters of the unit (e.g., exhaust temperature, lube oil pressure, rotor vibration value, valve opening) and eliminate interference signals through built-in data filtering and calibration algorithms to ensure the authenticity and validity of data.
3. Highly Reliable Redundant Communication and Collaboration
The IS210MACCH2AGG supports a dual redundant communication architecture: On one hand, it achieves high-speed data interaction (with a transmission rate of 160MB/s) with power modules, I/O modules, and communication modules in the system through the backplane bus (VME64x), ensuring collaborative response between modules; on the other hand, it is equipped with 2 Gigabit Ethernet ports, supporting industrial Ethernet protocols such as PROFINET and EtherNet/IP. It can realize data interconnection with upper-level monitoring systems (e.g., GE CIMPLICITY) and plant-level monitoring information systems (SIS), upload unit operating data in real-time (e.g., real-time working conditions, alarm information, historical trends), and receive remote control commands simultaneously, enabling a dual management mode of "local control + remote monitoring". In addition, the board also supports the Modbus RTU protocol, which is compatible with third-party intelligent equipment (e.g., smart meters, frequency converters), enhancing the flexibility of system integration.
4. Comprehensive Fault Diagnosis and Protection
The board has built-in comprehensive self-diagnosis and fault-tolerance mechanisms: By real-time monitoring its own power supply voltage, core chip temperature, and communication link status, it can early warn of potential hardware faults (e.g., power supply abnormalities, chip overheating, communication interruption) and intuitively feed back the status through LED indicators (power light, running light, fault light); it supports redundant voting logics such as "two-out-of-three" and "one-out-of-two". When a sensor signal in one channel is abnormal, it can automatically switch to a backup signal to avoid false triggering of protection actions; for key turbine faults (e.g., overspeed, overtemperature, low lube oil pressure), it can quickly execute emergency shutdown commands, cut off fuel supply or trigger trip solenoid valves, with a response time ≤ 50ms, minimizing the risk of equipment damage.
