IS200TBAIH1C | GE | Analog Input Terminal Board

Configured for analog signal conditioning and distribution in Mark VI turbine control architectures, the GE IS200TBAIH1C (IS200TBAIH1C Analog Input Terminal Board) provides direct physical and electrical execution of multi-channel sensor input routing and analog output regulation.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The IS200TBAIH1C integrates into the Mark VI control platform as a primary interface for analog instrumentation. The board supports backplane bus communication velocity by utilizing high-density DC-37 connectors for interfacing with I/O processors in both simplex and Triple Modular Redundant (TMR) configurations. Firmware flash compatibility is handled by the associated I/O packs to ensure precise signal scaling and I/O density scaling. The input/output circuits incorporate noise suppression hardware to mitigate surge and high-frequency interference, ensuring signal integrity. In TMR applications, the board utilizes internal measuring shunts to combine output driver signals, enabling the controller to regulate total current to the specific setpoint required for turbine control.

Frequently Asked Questions

Q: Is the IS200TBAIH1C board hot-swappable while the turbine control system is active?

A: No. Terminal board replacement requires the system to be in a non-operational state. Removing the board while energized will cause communication loss with I/O processors and potential damage to the DC-37 pin interface.

Q: Can the board be configured for mixed simplex and TMR operation?

A: The board supports TMR via all three connectors or simplex on one connector (UR1). Configuration must be consistent with the backplane I/O processor setup to prevent signal routing errors.

Field Installation Guidelines

1. Mounting: Secure the terminal board to the mounting plate within the control cabinet. Ensure all chassis grounds are established to maintain the efficacy of the integrated noise suppression circuitry.
2. Wiring: Terminate field inputs to the terminal blocks. Ensure that external power sources for transmitters are properly isolated and fused as per the system electrical schematic.
3. Connectivity: Connect the DC-37 cables to the R, S, and T interface ports based on the system architecture (simplex or TMR). Verify that connectors are fully seated and locking mechanisms are engaged.
4. Environment: Verify the cabinet ambient temperature is within the industrial operating range. Ensure adequate ventilation to prevent thermal drift of the precision measuring shunts.
5. Verification: Prior to startup, perform a loop check for each of the 10 analog inputs. Use the controller diagnostic interface to confirm that input signals match field transmitter outputs and that output mA values are within configured setpoint limits.
