IS200TBAIH1CCC is a GE Mark VI / Mark VIe TBAI Analog Input/Output Terminal Board. It provides the field termination and signal interface between analog sensors/transmitters and the Mark VI/Mark VIe I/O processing system.

Core Functions
Analog signal acquisition — provides 10 analog input channels for process measurement signals.
Multiple transmitter support — supports 2-wire, 3-wire, 4-wire, and externally powered transmitters.
Analog voltage/current inputs — inputs can be configured for voltage or current operation using onboard jumpers.
Analog output interface — provides 2 analog outputs, with configurable current ranges including 0–20 mA and, depending on the circuit/configuration, 0–200 mA.
24 VDC transmitter supply — provides excitation power for connected field transmitters.
Signal conditioning and noise suppression — helps maintain analog signal integrity in industrial environments.
Field wiring termination — provides terminal connections for sensors, transmitters, and analog actuators.
I/O processor connection — interfaces with the Mark VI/Mark VIe I/O processor; the TBAI architecture can be used with VAIC in Mark VI and PAIC in Mark VIe applications.
System identification/diagnostics — the board includes identification circuitry used by the I/O system for diagnostics and configuration.
