GE IS220PPROS1B Emergency Turbine Protection I/O Pack Mark VIe

GE IS220PPROS1B Emergency Turbine Protection I/O Pack

Product Description:

The GE IS220PPROS1B is an Emergency Turbine Protection I/O Pack part of the Mark VIe Series, critical for GE Distributed Control Systems. It provides backup overspeed protection, generator synchronization checks, and acts as an independent watchdog for primary controls. Paired with terminal boards, it forms a robust safety system—typically using three Triple Modular Redundant PPRO packs on an SPRO terminal board. Fully independent of primary controls, it monitors trip board status and triggers backups if faults occur, enhancing turbine safety.

Key Features:
Core Protection Functions: Delivers backup overspeed protection, generator synchronization verification, and independent oversight of primary controls to ensure turbine safety.

Redundancy & Compatibility: Supports TMR and simplex configurations; mounts directly on SPRO/TREA terminal boards, with cable compatibility for TREG, TREL, TRES, and TREA.

Installation Flexibility: Installs via threaded posts with bracket adjustment to avoid connector stress; connects to Ethernet and power with soft-start current limiting, configurable via ToolboxST.

Reliable Operation: Processor board integrates soft-start circuits, self-tests, and application code matching. Dual 10/100 Ethernet ports operate simultaneously, with faults indicated via active networks.

Hardware Traits: Includes high-speed CPU, watchdog timer, internal temperature sensor, status LEDs, and electronic ID reading. Local power supplies with monitoring ensure stable performance in harsh industrial environments.
