The IS200STAIH2ACB is a compact, high-density analog input terminal board designed for the GE Mark VI and Mark VIe control platforms. It serves as the interface layer between field analog devices and the turbine control processor, enabling reliable acquisition of process signals in space-constrained control cabinets.
This board supports 10 analog input channels and includes two configurable current output channels. An integrated on-board ID chip allows the controller to automatically recognize the board revision and configuration, simplifying commissioning, asset tracking, and maintenance diagnostics.

The IS200STAIH2ACB is widely deployed in power generation environments, particularly within:
Gas turbine control panels
Steam turbine control systems
Combined-cycle power plants
It is commonly used for interfacing:
Temperature transmitters
Pressure transducers
Flow meters
Auxiliary analog instrumentation
Its compact footprint and high channel density make it ideal for retrofit cabinets and high-speed turbine control applications where space optimization is critical.
Can the output channel drive high-current actuators?
Yes. While both outputs support standard 0–20 mA signaling, one channel can be configured to deliver up to 200 mA for specialized instrumentation or actuator requirements.
Is this board compatible with redundant systems?
The IS200STAIH2ACB is designed for simplex operation. For TMR (Triple Modular Redundant) architectures, verify that the overall system configuration supports integration of simplex terminal boards within a redundant framework.
