Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the IS220PTCCH1B. Always verify firmware compatibility and terminal board pairing before substitution:
- IS220PTCCH1A — Earlier hardware revision; functionally equivalent, verify firmware version
- IS220PTCCH1C — Later revision with minor hardware updates; drop-in compatible in most Mark VIe configurations
- IS215PTCCH1A — Mark VI series predecessor; requires terminal board and firmware evaluation
- IS200PTCCH1A — Mark VI legacy module; not directly interchangeable without engineering review
- IS220PTCCH2B — Enhanced variant; confirm I/O pack and terminal board compatibility
Note: Replacement suitability depends on your specific Mark VIe system revision, terminal board (PTCCH), and GE ToolboxST configuration. Contact Konmask for pre-sales compatibility verification.
Why Choose the Original IS220PTCCH1B
- OEM Accuracy: Factory-calibrated for GE Mark VIe systems — no re-engineering required
- Seamless Integration: Plug-and-play with existing PTCCH terminal boards and IONet infrastructure
- Proven Reliability: Deployed in gas turbine, steam turbine, and combined-cycle power plants worldwide
- Full Diagnostics: Supports GE ToolboxST online diagnostics, fault logging, and health monitoring
- Long Service Life: Designed for continuous 24/7 industrial operation in demanding environments
Typical Applications
- Gas turbine exhaust temperature monitoring (EGT)
- Steam turbine inlet/outlet temperature measurement
- Combined-cycle power plant DCS integration
- Industrial boiler and heat exchanger process control
- Compressor station temperature instrumentation
- Petrochemical and refinery process automation
System Compatibility
- DCS Platform: GE Mark VIe (primary); limited compatibility with Mark VI (requires engineering review)
- Terminal Board: PTCCH (IS200PTCCH1A or equivalent)
- I/O Pack Interface: IONet Ethernet-based communication
- Configuration Tool: GE ToolboxST (version compatibility per GE release notes)
- Redundancy: Supports simplex and TMR (Triple Modular Redundancy) configurations
Selection Guide
Use the following criteria to confirm IS220PTCCH1B is the correct module for your application:
- ✅ Your DCS is GE Mark VIe (not Mark VI or Mark VIes)
- ✅ You require thermocouple inputs (not RTD — for RTD, see IS220PRTDH1B)
- ✅ Your terminal board is PTCCH series
- ✅ You need 12 input channels per module
- ✅ Your system uses IONet communication (not legacy serial)
- ⚠️ If you need RTD inputs → consider IS220PRTDH1B
- ⚠️ If you need analog voltage/current inputs → consider IS220PVIBH1B or IS220PAICH1B
- ⚠️ If your system is Mark VI (not Mark VIe) → contact us for legacy module options

Replacement & Compatibility FAQ
Q: Can IS220PTCCH1A replace IS220PTCCH1B?
A: In most cases yes — both are hardware revisions of the same module family. Verify firmware compatibility in ToolboxST before swapping in a live system.
Q: Is IS220PTCCH1B compatible with Mark VI (not Mark VIe)?
A: No. Mark VI and Mark VIe use different I/O architectures. IS220PTCCH1B is designed exclusively for Mark VIe. Contact us for Mark VI alternatives.
Q: What is the difference between IS220PTCCH1B and IS220PRTDH1B?
A: IS220PTCCH1B handles thermocouple inputs (J, K, T, E, R, S, B, N types); IS220PRTDH1B handles RTD inputs (PT100, PT1000, etc.). They are not interchangeable.
Q: Do you provide a test report with the module?
A: Yes. A functional test report is available upon request for all refurbished and tested-used units.
Q: What is the lead time?
A: In-stock units ship within 1–2 business days. Out-of-stock items typically have a 2–4 week lead time. Contact us for real-time availability.
