Structure and Composition

• Front Connector/Terminal Block: Provides physical connection points for field sensor cables, usually using screw terminals or pluggable terminal blocks for easy wiring and maintenance. Each channel corresponds to an independent terminal.
• Signal Conditioning Circuit: Each input channel is equipped with an independent signal conditioning circuit, which may include precision resistors, operational amplifiers, filter circuits (RC filters), and surge protection components (such as TVS diodes, fuses). This part is responsible for signal scaling, filtering, clamping, and converting current signals to voltage signals (if applicable).
• Multiplexer (MUX): Sequentially switches analog signals from multiple channels to the subsequent common processing circuit, reducing costs and minimizing volume.
• Analog-to-Digital Converter (ADC): A core component that converts the conditioned analog voltage signals into digital values processable by the control system. The IC3600ALTC uses a high-precision, high-resolution ADC chip.
• Isolation Circuit: Uses optocoupler isolators or transformer isolation technology to provide electrical isolation between input channels, between input channels and the module’s internal logic circuits, eliminating ground loop interference and improving noise immunity and safety.
• Logic Control Circuit: Contains a microcontroller or programmable logic device (PLD) responsible for controlling the multiplexer switching timing, ADC start and read operations, data temporary storage, and data exchange with the Mark IV main controller through the backplane interface.
• Status Indicators (LEDs): Usually located on the front of the module, providing visual indicators for power, channel status, faults, etc.
• Backplane Interface Connector: Gold fingers or high-density connectors used to insert the module into the Mark IV rack, obtain operating power, and communicate with the system backplane bus.

Key Features and Advantages

• High Precision and Reliability: Uses precision signal conditioning components and high-performance ADCs to ensure that the measurement accuracy of key process variables (such as temperature, pressure) reaches industry-leading levels, meeting the stringent control accuracy requirements of gas/steam turbines. Strict component screening and manufacturing processes ensure long-term reliable operation in harsh industrial environments.
• Excellent Signal Integrity: Powerful inter-channel and system-level isolation technology (usually up to 1500V AC) effectively suppresses common-mode interference, ground loop noise, and transient voltage surges, ensuring the purity and stability of signal acquisition in the high electromagnetic interference environment of power plants.
• Modularity and Maintainability: As a standard Mark IV card, the IC3600ALTC supports hot swapping (when allowed by the system design), facilitating quick replacement and repair, significantly reducing downtime and maintenance costs. Clear LED status indicators help quickly locate faults.
• Optimized for Turbine Control: This module is a native component of the GE Mark IV Speedtronic™ system, specially designed and tested to seamlessly integrate with the system’s controllers, software, and rack architecture, providing optimal performance and compatibility to ensure the coordinated and efficient operation of the entire control system.
• Rugged Industrial Design: Complies with industrial environmental standards (wide operating temperature range), able to withstand vibration, temperature fluctuations, and electrical noise in power plant control rooms, ensuring a long service life.
• Mature Platform Support: Relying on the widely deployed and time-tested GE Mark IV platform, spare parts and technical support resources are relatively abundant (although it has been discontinued, the ecosystem is still maintained).

Application Fields

• Power Generation: This is its primary application scenario. It is widely used in the main control and protection systems (Mark IV) of gas turbine generator sets and steam turbine generator sets. It accurately collects dozens or even hundreds of key analog signals such as combustion chamber temperature, exhaust temperature, bearing temperature, lubricating oil pressure, fuel flow, steam pressure/temperature, etc., providing real-time and accurate input data for speed control, load control, temperature control, sequence start-stop logic, and over-temperature and over-pressure protection functions, and is the core foundation for ensuring the safe, efficient, and environmentally friendly operation of the unit.
• Combined Cycle Power Plants: In gas-steam combined cycle (CCPP) power plants, it serves the control systems of both gas turbines and heat recovery boilers/steam turbines.
• Industrial Drives: Used in the control systems of industrial gas turbines or steam turbines that drive large compressors, pumps, and other key equipment.
• Protection of Key Equipment in Process Industries: In petrochemical, metallurgical, and other process industries, it provides control signal acquisition for steam turbines driving large key equipment (such as cracking gas compressors).
