| IS220YTURS1C | Mark VI | Later revision; verify IONet firmware version compatibility |
| IS220PTURH1A | Mark VI | High-density turbine I/O variant; check channel count requirements |
| IS220PAICH1A | Mark VI | Analog I/O pack; suitable if application requires analog signal processing |
| IS220PDOAH1A | Mark VI | Digital output pack; use when digital output channels are the primary need |
Note: Konmask.com recommends consulting your GE Mark VI system documentation or contacting our technical team before substituting I/O packs.
Why Choose the Original IS220YTURS1A
- OEM-certified compatibility — engineered specifically for GE Mark VI turbine control architecture
- Validated IONet communication — ensures deterministic, low-latency signal exchange with the Mark VI controller
- Proven field reliability — widely deployed in gas turbine, steam turbine, and combined-cycle power plant applications
- Firmware traceability — original part numbers maintain full revision history for compliance and audit purposes
- Reduced integration risk — eliminates the need for re-engineering or reconfiguration associated with cross-brand substitutions
Typical Applications
- Gas turbine control systems (GE Frame 5, Frame 6, Frame 7, Frame 9 series)
- Steam turbine governor and protection systems
- Combined-cycle power plant automation
- Compressor control and surge protection
- Industrial process control requiring Mark VI I/O infrastructure
System Compatibility
| System | Compatible | Notes |
|---|---|---|
| GE Mark VI | ✅ Yes | Primary target platform |
| GE Mark VIe | ⚠️ Verify | Check IONet protocol version; some IS220 packs are cross-compatible |
| GE Mark V | ❌ No | Different I/O architecture; not compatible |
| Third-party DCS | ❌ No | Proprietary IONet protocol; not compatible with non-GE controllers |
Selection Guide
Use the following criteria to determine whether the IS220YTURS1A is the correct module for your application:
- Step 1 — Confirm controller platform: Verify your system is GE Mark VI (not Mark V or Mark VIe without compatibility confirmation).
- Step 2 — Identify I/O type required: IS220YTURS1A is a turbine-specific I/O pack; confirm your application requires turbine signal conditioning.
- Step 3 — Check hardware revision: Match the suffix (A, B, C) to your existing rack and firmware version to avoid revision mismatches.
- Step 4 — Verify channel count: Confirm the number of input/output channels required matches the IS220YTURS1A specification for your loop design.
- Step 5 — Assess replacement urgency: For emergency replacements, contact Konmask.com for expedited sourcing of tested or new units.

Replacement & Compatibility FAQ
Q: Can IS220YTURS1B replace IS220YTURS1A directly?
A: In most Mark VI configurations, yes. The B revision is a hardware update with the same functional role. Confirm with your GE system integrator for safety-critical applications.
Q: Is IS220YTURS1A compatible with Mark VIe?
A: Compatibility depends on the specific Mark VIe configuration and IONet firmware version. Contact our technical team for a compatibility assessment.
Q: What is the lead time for a new IS220YTURS1A?
A: In-stock units ship within 3–7 business days. For sourced units, typical lead time is 2–4 weeks. Contact us for urgent requirements.
Q: Do you provide a warranty on refurbished units?
A: Yes. Refurbished units carry a 90-day functional warranty. New units follow manufacturer warranty terms where applicable.
Q: Can I return a module if it is not compatible?
A: Please contact [email protected] within 7 days of receipt. Returns are accepted for unused, uninstalled units in original packaging.
