GE IS200TBAIS1C – Analog Input Terminal Board for Mark VI Turbine Control

The GE IS200TBAIS1C is an Analog Input terminal board used in GE Mark VI turbine control cabinets to bring field analog signals cleanly into the control system. From my experience, the “S1C” variant denotes a simplex hardware configuration, which is exactly what many single-channel applications require. Plants typically use it to land 4–20 mA and voltage signals from pressure, temperature, and process transmitters—without reworking the cabinet layout. You might notice that it seems to be a straightforward drop-in when replacing an older TBAI board in a Mark VI panel.

One thing I appreciate is the field-friendly wiring: clear terminal designations, robust screw terminals, and a direct connector interface to the associated I/O hardware. In retrofit jobs, that consistency cuts downtime. A maintenance lead at a combined-cycle site told us, “the board lined up with our drawings and loop checks were smooth; no surprise re-terminations.”

Order Placement Process and Guarantees

• Express Shipping: FedEx, UPS, DHL

Key Features

• Simplex analog input termination – The S1C configuration is typically used where single-channel I/O is appropriate, keeping design and maintenance simple.
• Supports common process signals – Designed for landing industry-standard current and voltage analog inputs used across gas/steam turbine auxiliaries and balance-of-plant.
• Clean integration with Mark VI – Mates to the GE I/O hardware via board-to-cable connectors; no external communication setup required.
• Noise-conscious signal conditioning – GE terminal boards are known for practical filtering and grounding provisions that help keep loops quiet in real cabinets.
• Service-friendly wiring – Screw terminals and clear labeling streamline loop checks, commissioning, and future troubleshooting.
• Cabinet-ready footprint – Fits standard Mark VI terminal board locations; from my experience, swap-outs are typically quick.

Installation & Maintenance

• Cabinet environment: Install in a clean, dry control cabinet with adequate ventilation. Maintain panel ambient per Mark VI guidelines.
• Wiring practices: Use shielded twisted pairs for analog loops; land shields per site grounding standard. Separate low-level signals from power cabling.
• Mounting: Secure the board on its designated standoffs/locations. Verify connector seating to the associated I/O hardware before energizing.
• Safety: De-energize affected loops, apply ESD protection, and tag-out before handling terminals. Confirm polarity for current loops.
• Commissioning: Perform loop checks (zero/span), verify scaling in the control logic, and document terminal assignments against the drawings.
• Routine care: Periodically re-torque terminal screws, inspect for corrosion or loosened shields, and clean dust with dry air. The terminal board itself has no firmware; any updates pertain to the controller/I/O packs.
