GE IS200TPROH1BBB

Description

Product Overview: The GE IS200TPROH1BBB Terminal Board

The GE IS200TPROH1BBB is a critical interface terminal board (also called a I/O pack carrier or base unit) designed for the Mark VIe Speedtronic turbine control system from GE (now part of Baker Hughes and often supported by Emerson Ovation). This specific model is a Termination Panel designed to house and provide the electrical connection interface for various I/O packs, such as analog input, digital output, or communication modules. The IS200TPROH1BBB does not contain active control logic; instead, it provides the robust, high-density wiring terminals, signal conditioning circuitry, and the backplane connection that allows a removable I/O Pack to interface with field devices and the turbine’s central controller. For all installation and compatibility details, engineers must consult the official Mark VIe system documentation for the IS200TPROH1BBB.

Product Parameters and Technical Specifications

• Function: Termination Panel / I/O Pack Carrier for Mark VIe system.

• Compatible I/O Packs: Designed to accept specific, corresponding I/O Packs (e.g., a analog input pack like the IS200AEPAH1B would plug into its matching terminal board). The “PROH” in the part number indicates its design family.

• Terminations: Features a high number of screw terminal or spring-clamp connections for field wiring from sensors, actuators, and other devices. The exact number and type (e.g., for voltage, current, RTD, relay contacts) are defined by its specific design.

• Internal Conditioning: May include passive components like resistors, fuses, and/or transient protection devices for signal conditioning and field-side protection.

• Backplane Interface: Contains the connector and circuitry to interface the plugged-in I/O Pack with the Mark VIe’s IONet (I/O Network) backplane for communication with the central controller.

• Form Factor: Mounts on a DIN rail or panel within a Mark VIe control cabinet. The removable I/O Pack plugs directly into the front of the IS200TPROH1BBB.

Advantages and Key Features

• Modular and Serviceable Design: The separation of the terminal board (IS200TPROH1BBB) from the active I/O Pack allows for easy maintenance and replacement. A faulty I/O pack can be swapped without disturbing the field wiring connected to the terminal board.

• High-Density and Robust Termination: Provides a secure, industrial-grade interface for a large number of field wires, essential for the complex I/O requirements of a gas or steam turbine.

• Integrated Signal Conditioning: Built-in protection and conditioning circuits help ensure signal integrity and protect sensitive control electronics from field-side voltage spikes and noise.

• System Integration: Engineered for seamless mechanical and electrical integration within the Mark VIe rack, ensuring reliable communication and power delivery to the I/O Pack.

• Critical System Reliability: As a core component of a turbine safety and control system, the IS200TPROH1BBB is built to the highest standards of quality and durability to operate in demanding power generation environments.

Application Cases in Industry

• Gas Turbine Control Cabinets: Serving as the termination point for critical signals such as flame detector inputs, fuel valve position feedback, and turbine speed sensors within a Mark VIe control system.

• Steam Turbine Protection Systems: Providing the interface for emergency trip solenoid outputs, bearing temperature monitor inputs (RTDs/thermocouples), and valve limit switch inputs.

• Turbine Auxiliary Skid Control: Housing I/O for lube oil system monitoring (pressure, temperature switches) and control of auxiliary cooling fans or pumps.

• Power Generation Plant: Used across various turbine control applications where the GE Mark VIe platform is the designated control system.

Comparison with Competing Products
This product is not a generic PLC terminal block. It is a proprietary, system-specific component. A comparison would be against terminal boards from other major turbine control OEMs, such as Siemens (for their SGT-800/900 or SPPA-T3000 control systems) or Woodward (NetCon system). The GE IS200TPROH1BBB is distinguished by its exclusive mechanical and electrical design to work with the Mark VIe I/O Pack form factor and IONet communication backplane. Compared to a standard industrial PLC’s I/O module which combines termination and electronics in one unit, the Mark VIe’s separated design (terminal board + pack) offers superior serviceability for critical, high-availability turbine applications.

Selection Suggestions and Precautions

• Selection Advice: The GE IS200TPROH1BBB is selected exclusively for constructing, repairing, or expanding a GE Mark VIe turbine control system. Selection is not independent; it must be chosen to precisely match the specific I/O Pack (e.g., a digital input pack, analog output pack) that will be installed onto it. The part number defines the signal types and terminations provided.

• Precautions:

  1. Exact Compatibility is Mandatory: The terminal board and I/O Pack must be a matched set as defined by GE’s system documentation. Using an incorrect combination will result in non-operation or damage.

  2. Handling of Bare Board: When an I/O Pack is removed, the exposed connectors on the IS200TPROH1BBB are static-sensitive and can be contaminated. Use protective covers and ESD precautions.

  3. Torque Specifications: Field wiring terminal screws must be torqued to the precise specification to ensure a reliable connection without damaging the terminal block.

  4. Configuration Dependency: The overall I/O point (defined by the terminal board and I/O pack combination) must be correctly configured in the Mark VIe engineering tool (ToolboxST) for the controller to recognize and use it.

  5. Authoritative Reference: All wiring, installation, and compatibility checks must be performed using the official Mark VIe documentation for the IS200TPROH1BBB. Incorrect wiring can lead to control system faults or equipment damage.
