GE IS220PDIOH1B – Discrete I/O Input Module | Mark VIe Gas Turbine Control Platform
Engineering Background
The IS220PDIOH1B is a high-density discrete I/O input module engineered by GE (General Electric) as a core component of the Mark VIe Turbine Control System — GE’s flagship distributed control architecture for gas turbines, steam turbines, and combined-cycle power generation assets. Designed to operate within the IS220 I/O board family, this module provides reliable digital signal acquisition in demanding industrial environments where signal integrity and deterministic response are non-negotiable.
Product Positioning
Procurement engineers sourcing replacement or expansion I/O for GE Mark VIe installations will find the IS220PDIOH1B to be a direct, form-fit-function compatible solution. Konmask.com maintains verified stock of this module, fully tested against GE factory specifications, and ready for immediate deployment in both brownfield retrofits and greenfield turbine control projects.

- Redundancy Support: Compatible with TMR (Triple Modular Redundancy) and dual-redundant Mark VIe architectures.
- Robust EMI Immunity: Designed to IEC 61000-4 series standards for operation in high-noise power generation environments.
- Hot-swap Capable: Supports live replacement in Mark VIe systems with appropriate configuration, minimizing planned outage windows.
System Architecture & Signal Flow
Within the Mark VIe architecture, the IS220PDIOH1B resides on the I/O pack backplane and communicates upstream to the VCMI (VME Communications Module Interface) or UCSC controller via the IONet Ethernet ring. Discrete field signals (limit switches, proximity sensors, valve position feedback, relay contacts) are wired to the module’s terminal block. The module digitizes these signals and transmits status data to the Mark VIe controller at the configured scan rate. In TMR configurations, three IS220PDIOH1B modules operate in parallel with voted outputs, ensuring SIL-2 / SIL-3 capable protection logic.

Technical FAQ
- Q: Is the IS220PDIOH1B compatible with Mark VI (non-VIe) systems?
- A: No. The IS220 series is designed exclusively for the Mark VIe platform. Mark VI uses a different I/O board family (IS200 series). Please confirm your controller generation before ordering.
- Q: Can this module be used in a simplex (non-redundant) Mark VIe configuration?
- A: Yes. The IS220PDIOH1B operates in simplex, dual-redundant, and TMR configurations. Simplex use requires appropriate Mark VIe toolbox configuration.
- Q: What is the difference between IS220PDIOH1A and IS220PDIOH1B?
- A: The H1B is a later hardware revision with minor PCB and component updates. Both revisions are functionally equivalent in most applications; consult your GE Mark VIe release notes for revision-specific compatibility advisories.
- Q: Do you provide a test report with shipment?
- A: Yes. A functional test report is included with every unit shipped from Konmask.com.
- Q: Can Konmask assist with Mark VIe system integration or configuration?
- A: We provide hardware supply and pre-shipment testing. For on-site commissioning and Mark VIe toolbox configuration, we can refer qualified GE-certified service partners.
