Description

Product Overview

The IS220PPROS1B Backup Turbine Protection I/O Pack from General Electric’s Mark VIe series delivers independent overspeed and synchronization protection for turbine systems. It supports triple modular redundancy (TMR) and integrates with emergency trip boards such as TREG, TREL, TRES, and TREA.

This module accepts three speed signals including acceleration, deceleration, and hardware-based overspeed. It monitors the primary control system and provides watchdog functionality. The IS220PPROS1B communicates via Ethernet using IONet protocol and connects through DC-37 pin cables to simplex protection boards like SPRO.

Its compact form factor and robust design make it ideal for field-mounted enclosures in critical turbine protection environments.
