Overview

IS220PPROS1B is a protection I/O pack designed for GE Speedtronic Mark VIe turbine control system. It delivers hardware overspeed protection and emergency trip functions for gas turbines and aeroderivative turbine units. This module receives speed signals and executes fast protection action to shut down the turbine once abnormal speed conditions are detected. The IS220PPROS1B works together with matched terminal boards for field wiring connection. It can be deployed in simplex, duplex or TMR triple modular redundant configurations to meet power plant safety requirements.

Key Features

• Dual 10/100Mbps full-duplex Ethernet ports for IONet communication
• Front panel LED indicators for PWR, RUN, LINK, ATTN, ESTP and watchdog status for quick on-site troubleshooting
• Built-in IR local service port for module configuration and maintenance
• Independent hardware overspeed protection, not relying on software logic
• Optimized for turbine emergency trip safety loop
• Supports long distance field sensor wiring with specified cable gauge limits
• High reliability for continuous operation in power generation environments
