GE IS200TBCIH3C Contact Input Terminal Board | Replacement, Equivalent & Selection Guide
The GE IS200TBCIH3C is a Contact Input Terminal Board designed for use in GE’s Mark VI Turbine Control System. It serves as the interface board for discrete contact (dry contact) input signals, enabling reliable signal conditioning and I/O connectivity in gas turbine, steam turbine, and combined-cycle power plant control architectures. Konmask.com supplies both new and tested-surplus IS200TBCIH3C boards with full traceability.

Compatible Replacement & Equivalent Models
The following boards are functionally compatible or serve as direct/near-direct replacements for the IS200TBCIH3C in Mark VI control panels:
- IS200TBCIH1C — Earlier hardware revision; same electrical function, verify firmware compatibility
- IS200TBCIH2C — Intermediate revision; drop-in replacement in most Mark VI cabinets
- IS200TBCIH4C — Later revision with minor PCB updates; backward-compatible
- IS200TBCIH5C — Latest known revision; confirm with GE BOM before substitution
- IS200TBAIH1C — Analog Input Terminal Board (different signal type; not a direct swap)
Always verify the revision letter against your Mark VI cabinet BOM and GE engineering drawing before substitution.

Selection Guide
Use this guide to confirm the correct terminal board for your application:
- Signal type is dry contact / voltage-free? → IS200TBCIH3C ✓
- Signal type is 4–20 mA or thermocouple? → Consider IS200TBAIH or IS200TBCCH series
- Need RTD input? → IS200TBCCH series
- Cabinet revision C or later? → IS200TBCIH3C is the recommended stock revision
- Unsure of revision? → Contact Konmask with your cabinet serial number for a verified match

Replacement & Compatibility FAQ
Q: Can IS200TBCIH2C replace IS200TBCIH3C?
A: In most Mark VI cabinets, yes — the H2C and H3C share the same electrical design. Confirm against your GE BOM.
Q: Is IS200TBCIH3C compatible with Mark VIe?
A: No. Mark VIe uses a different I/O architecture (ETM/IONet). A separate terminal board family is required.
Q: Do you provide a warranty?
A: Yes — 12-month warranty on all tested-surplus units; 24-month on new OEM stock.
Q: Can you source other IS200 series boards?
A: Yes. Contact us with your full part number list for a consolidated quote.
Q: What is the lead time for IS200TBCIH3C?
A: In-stock units ship within 1–3 business days. Contact us to confirm current stock status.
