GE IS200TBAOH1C Key features
Supports 16 current loop outputs for precise analog control
Boards include potentiometers for per-channel calibration
Conformal coating protects against moisture and contaminants
Six front-panel jacks facilitate easy wiring and diagnostics
Compatible with both Mark VI and Mark VIe systems
MAINTENANCE:
Periodically clean and inspect terminal blocks and connector pins
Adjust potentiometers annually to correct drift
Monitor output consistency using a loop calibrator
Replace board if channel malfunctions or coating degrades


Performance comparison
Parameter | IS200TBAOH1C | IS200TBAOH1B |
Output Channels | Same | 16 × 0–20 mA |
PCB Coating | Conformal-coated | Standard |
System Support | Mark VI/Speedtronic | Mark VIe |
Noise Suppression | Basic (via external VAOC) | Yes |
Summary:
IS200TBAOH1C and IS200TBAOH1B both offer 16 analog outputs, but C-version uses conformal coating and Mark VI compatibility. B-version adds noise suppression and suits Mark VIe systems.
Typical cooperation cases
Europe – EDF Gravelines Nuclear Plant
Installed in analog output racks to regulate turbine valve positions for unit control modernization in France’s largest nuclear facility.
Asia – Sinopec Maoming Refinery Upgrade
Used in compressor control panels providing analog signal loops during major automation overhaul of refinery skid systems.
North America – TVA Gallatin Fossil Plant Retrofit
Added to Mark VI cabinets to replace obsolete terminal boards with conformal-coated alternatives during turbine upgrade project.
