Description
1. Product Title
GE IS200TTURH1CCC – Mark VI Primary Turbine Protection Termination Board
2. Product Overview
TheIS200TTURH1CCC is a critical Turbine Primary Protection (TTUR) termination board designed for the GE Mark VI Speedtronic control system. This module serves as the primary interface for essential turbine safety and monitoring functions, specifically handling inputs for turbine speed, overspeed protection, and synchronization. Its role is to bridge the gap between field-mounted sensors and the VME-based I/O processors (typically the VTUR or PTUR modules).
In high-speed power generation, precise speed monitoring is a non-negotiable safety requirement. TheIS200TTURH1CCC solves the industrial challenge of high-frequency signal integrity by providing specialized circuitry for Magnetic Pickup (MPU) sensors. It monitors the turbine’s rotational velocity and provides the hardware-level data required to trigger emergency trips during overspeed events. Additionally, it handles generator and bus voltage inputs for the automatic synchronization process, ensuring the turbine safely connects to the electrical grid.
