Description

The GE IS200VAICH1CBA is a high‑density Analog Input/Output (VAIC) board engineered for the Mark VI Speedtronic™ gas turbine control system. Part of the original VAIC generation, the GE IS200VAICH1CBA conditions 24 channels of 4‑20 mA analog signals from field sensors, converting them via a 16‑bit A/D converter into digital data for real‑time turbine management. An onboard Intel Celeron 300 MHz processor executes local signal conditioning and diagnostics, offloading the main controller. The GE IS200VAICH1CBA supports both simplex and Triple Modular Redundant (TMR) configurations, providing fault‑tolerant operation for mission‑critical analog loops without single‑point failure risk.

Applications

Gas turbine control systems – fuel valve positioning, speed regulation, exhaust temperature monitoring
Steam turbine control – governor control, inlet steam pressure, valve position feedback
Generator excitation – field current/voltage sensing and control, synchronisation loops
Plant auxiliary systems – compressor suction/discharge pressure, bearing temperature, vibration monitoring
Flame detection – interfaces with up to 8 Geiger‑Mueller detectors per board for combustion monitoring

Features

24‑channel high‑density I/O – 20 analog inputs (4‑20 mA) and 4 analog outputs (configurable 0‑20 mA) in a single VME slot, maximising rack space efficiency
16‑bit A/D resolution – ±0.02% typical accuracy for precise sensing of pressure, temperature, and flow transmitters
12‑bit D/A converters – generates high‑resolution analog output signals for controlling I/P transducers, actuators, and valves
Triple Modular Redundancy (TMR) – inputs fanned out to three parallel VAIC boards; outputs driven by all three with automatic faulty‑board removal for uninterrupted current loop operation
Onboard Intel Celeron 300 MHz processor – executes local linearisation, scaling, and diagnostics independently of the main controller
10 ms deterministic scan time – delivers consistent, predictable I/O update rates essential for real‑time turbine safety loops
100BaseTX Ethernet connectivity – RJ‑45 port provides high‑speed IONet communication with the Mark VI rack
Surface‑mount technology – rugged PCB construction with fully sealed components for industrial vibration and thermal resistance
128 MB flash memory – onboard non‑volatile storage for firmware and configuration data
Terminal board flexibility – compatible with TBAIH1B, TBAIH1C, DTAI, and STAI termination boards, supporting both original and high‑drive output generations

Functions

Acquires analog field signals – samples 20 independent 4‑20 mA loops from pressure, temperature, and flow transmitters at 10 ms intervals
Performs A/D conversion – transforms analog currents into 16‑bit digital values for use by the Mark VI controller algorithms
Executes local signal conditioning – scales, linearises, and filters sensor data onboard via the Intel Celeron processor before transmission
Generates analog outputs – converts digital setpoints from the controller into 0‑20 mA signals for driving actuators, I/P transducers, and valves
Supports TMR failover – in redundant configurations, automatically excludes a faulty VAIC board while the remaining two maintain the correct output current
Communicates via VME backplane – transfers processed I/O data to the VCMI board and onwards to the main turbine controller

FAQ

Q1: What is the IS200VAICH1CBA used for in a GE Mark VI system?
A1: The IS200VAICH1CBA is a VAIC (Analog Input/Output) board that interfaces field sensors and actuators with the Mark VI turbine controller, providing 20 analog inputs and 4 analog outputs with 16‑bit resolution.

Q2: Does the IS200VAICH1CBA support redundancy for critical loops?
A2: Yes. The IS200VAICH1CBA supports Triple Modular Redundancy (TMR): inputs are fanned out to three parallel VAIC boards, and outputs are driven by all three with automatic faulty‑board exclusion for fail‑safe operation.

Q3: What is the scan time of the IS200VAICH1CBA?
A3: The IS200VAICH1CBA provides a deterministic 10 ms scan time, ensuring consistent I/O update rates suitable for real‑time turbine safety loops and emergency trip parameters.

Q4: What terminal boards are compatible with the IS200VAICH1CBA?
A4: As a member of the original VAIC generation, the IS200VAICH1CBA requires terminal board TBAIH1B or earlier, or any revision of DTAI. It does not require TBAIH1C or STAI, which are for newer VAIC generations.

Q5: What types of analog signals does the IS200VAICH1CBA support?
A5: The IS200VAICH1CBA accepts 4‑20 mA analog inputs from field sensors; its four analog outputs can be configured as 0‑20 mA or 4‑20 mA to drive actuators and I/P transducers.
