GE IS220PSVOH1B – Industrial Power Supply Module | Mark VIe IS220 Platform
Engineering Background: The GE IS220PSVOH1B is a dedicated power supply module engineered for GE’s Mark VIe turbine control platform. Designed to deliver stable, conditioned DC power to I/O and control modules within the IS220 series architecture, it is a mission-critical component in gas turbine, steam turbine, and combined-cycle power generation systems worldwide.
Product Positioning: At Konmask.com, we source IS220PSVOH1B units through verified industrial channels, subjecting each module to a documented inspection process before dispatch. Whether you are commissioning a new turbine control panel or replacing a failed unit in an operating plant, we provide the reliability and traceability that procurement engineers demand.

Engineering Advantages
- Platform Compatibility: Designed exclusively for the Mark VIe IS220 ecosystem — plug-and-play replacement with no firmware reconfiguration required in most applications.
- Stable Power Delivery: Provides clean, regulated DC output that protects sensitive I/O modules from voltage transients common in industrial environments.
- Redundancy Support: Compatible with Mark VIe redundant power architectures (TMR and dual-redundant configurations).
- Compact Form Factor: Slot-in module design minimises panel downtime during replacement — critical for plants operating under tight maintenance windows.
- Long Service Life: Built to GE’s industrial-grade component standards for continuous duty in high-availability control systems.
System Architecture & Signal Flow
Within the Mark VIe architecture, the IS220PSVOH1B occupies the power distribution layer of the IS220 I/O terminal board assembly. DC bus power enters the module, is conditioned and regulated, then distributed to adjacent I/O modules (analog input, digital output, communication, etc.) via the backplane connector. The module interfaces directly with the VCMI or VCRC controller cards through the Mark VIe high-speed serial backplane, ensuring synchronised power sequencing during system startup and shutdown.
Typical signal flow: Plant 24 V DC Bus → IS220PSVOH1B → IS220 I/O Module Backplane → Field Instruments / Actuators
Sourcing & Quality Verification
Every IS220PSVOH1B unit shipped from Konmask.com passes through our 4-step verification protocol:
- Visual Inspection: Board-level examination for physical damage, corrosion, counterfeit markings, and component integrity.

Technical FAQ
Q: Is IS220PSVOH1B compatible with both TMR and simplex Mark VIe configurations?
A: Yes. The module is designed to operate in simplex, dual-redundant, and TMR (Triple Modular Redundant) Mark VIe panel configurations without hardware modification.
Q: Can I replace IS220PSVOH1B without shutting down the turbine?
A: In redundant power configurations, hot-swap replacement may be possible depending on your specific panel design. Always consult your GE Mark VIe system documentation and site safety procedures before attempting live replacement.
Q: Do you supply GE factory-new units or only surplus?
A: We supply both. Factory-new (sealed) stock is available subject to lead time; tested surplus units are typically available for immediate dispatch. Specify your preference when enquiring.
Q: What export documentation is provided?
A: We provide commercial invoice, packing list, certificate of origin, and — where required — an end-user declaration. HS Code 8537.10 applies to most shipments.
Q: What is your minimum order quantity?
A: MOQ is 1 unit. Volume pricing is available for orders of 5 units or more.
