GE IS200TBAIH1CCC

1. Overview

The GE IS200TBAIH1CCC is an Analog Input Terminal Board (TBAI) developed for the GE Mark VI and Mark VIe control systems. It provides a reliable interface for connecting analog signals from field transmitters, sensors, and process instruments to the system’s control modules. Designed for industrial automation and turbine control environments, the TBAI board ensures precise and stable signal measurement across a wide range of operating conditions.

The “H1CCC” version represents a later hardware revision, offering enhanced circuit protection, improved signal accuracy, and reinforced board construction, making it ideal for demanding, mission-critical applications.

2. Technical Specifications

The IS200TBAIH1CCC board supports up to 10 analog input channels, each capable of handling 4–20 mA, 1–5 V, or millivolt-level signals, depending on the sensor configuration. Every channel is differentially isolated to minimize noise interference and ensure precise data acquisition.

The board connects directly to I/O packs such as the IS220PAICH1A using a DC-37 pin connector, while field devices are connected through screw-type terminals for secure and easy wiring. The analog inputs can interface with various sensors, including pressure, flow, temperature, and position transmitters.

Built-in RC filtering and transient suppression components protect the board from surges and electrical noise. The TBAIH1CCC operates from –30°C to +65°C and draws power directly from the system backplane, eliminating the need for an external power source.
