IS220YPROS1AJ Functional Description
The IS220YPROS1AJ input/output module General Electric is an Emergency Turbine Protection I/O Pack from the Mark VIe Series, designed for GE Distributed Control Systems. It provides a backup overspeed protection system, performs generator synchronization checks, and acts as an independent watchdog for the primary control. A standard protection setup uses three triple modular redundant (TMR) General Electric IS220YPROS1AJ I/O Protection Module units connected to an SPRO terminal board, interfacing with various trip boards such as TREG, TREL, TRES, and TREA for different turbine types.
Each Mark VIe General Electric IS220YPROS1AJ communicates with control modules via Ethernet for IONet networking, integrating backup trip systems with the primary trip boards. It supports detection of overspeed, acceleration, and deceleration events through hardware-implemented speed monitoring. By independently monitoring the primary control’s performance, it can initiate a trip via backup relays if faults are detected, ensuring reliable turbine protection without interference from the main control system.
Physically, the IS220YPROS1AJ General Electric Backup Turbine Protection Modules is compact yet robust, measuring 14.3 cm by 23.1 cm, weighing 0.45 kg, and operating from a 24 V DC power supply within a temperature range of -30°C to 65°C. It can be mounted directly onto SPRO or TREA terminal boards, or connected to other trip boards via DC-37 pin cables. The unit’s threaded post and bracket system ensures secure installation and stable operation.
The Emergency Turbine Protection I/O Pack IS220YPROS1AJ General Electric is compatible with both simplex and dual main control configurations. In simplex setups, it supervises a single controller, while in dual control systems, it monitors both R and S controllers, tripping if either fails. Its rugged design, Ethernet connectivity, and precise protective functions make it a critical component in turbine safety and control applications.

General Electric Mark VIe I/O Pack Processing and Network Features
The General Electric Mark VIe I/O pack integrates a function-specific acquisition board with a high-performance processor board, ensuring efficient data handling and system reliability. Upon power-up, a soft-start circuit gradually applies voltage to the processor board, followed by a reset release, local power activation, and self-test execution. The processor then loads application code from flash memory, verifies compatibility with the acquisition and terminal boards, and establishes Ethernet connections by requesting a network address. Supporting one or two independent 10/100 Mbps Ethernet ports, the design ensures both ports remain active for enhanced fault tolerance, automatically adjusting between half- and full-duplex modes. Key hardware elements include a fast CPU with RAM and flash memory, watchdog timer, hardware reset circuit, temperature sensor, board ID reading capability, status LEDs, and local power supplies with current limiting and sequencing. This robust architecture ensures continuous, reliable operation in demanding industrial environments.
