GE IS200VPROH2B IS200VPROH1BEF IS200VPWRH1AHD Processor module

Description

GE IS200VPROH2B IS200VPROH1BEF IS200VPWRH1AHD 

The Speedtronic™ is a core component of the typical GE (General Electric) Mark VIe gas turbine/steam turbine control system. It is part of GE’s Speedtronic™ family and is designed for industrial power generation and mechanical drive applications.

Overall Product Description
These models together comprise the chassis and processor modules of the Mark VIe control system, used to monitor and control the operation of gas or steam turbines. The system ensures safe and efficient startup, operation, and shutdown of the unit, preventing hazardous conditions such as overspeed.

Detailed Function Breakdown
To understand how these modules work together within a typical Mark VIe system rack, the following diagram illustrates their logical placement and relationships:

1. IS200VPWRH1AHD – Power Supply Module
Function: This is the power supply unit for the Mark VIe control rack. It converts the plant’s incoming AC or DC power (e.g., 125 VDC or 240 VAC) into the low-voltage DC power required by all other electronic modules in the rack (processors, I/O modules).
Key Features: Designed for high reliability and availability in harsh plant environments. It often features redundant input capabilities, power factor correction, and comprehensive over-voltage and over-current protection to ensure continuous operation of the critical turbine control system.

 

2. IS200VPROH1BEF & IS200VPROH2B – Controller Modules (Processor)
Function: These are the brains of the control system, known as Controller Modules or Processor Modules. They execute the core control logic that governs the turbine’s operation (start-up, speed/load control, shutdown, sequencing, and protection).
Redundancy Configuration:

The IS200VPROH1BEF is typically configured as the Primary Controller.
The IS200VPROH2B is typically configured as the Redundant/Backup Controller.
Operation: They receive data from turbine sensors (e.g., speed, temperature, pressure), execute complex control algorithms, and send output commands to actuators (e.g., fuel valves, inlet guide vanes). The redundant pair operates in a hot-standby mode; if the primary controller fails, the system automatically and seamlessly switches to the backup controller without shutting down the turbine. This is critical for high availability and safety.

Typical Applications
These modules are used in control systems for:

Gas Turbine Generator Sets
Steam Turbine Generator Sets
Mechanical Drive Gas Turbines (e.g., for pipeline compression)
