GE IS220PDOAH1B – 16-Channel Discrete Output Module | Mark VIe Control Platform
Engineering Background: The IS220PDOAH1B is a high-density discrete output (DO) I/O module engineered by GE Vernova for the Mark VIe distributed control system platform — the industry benchmark for turbine control, power generation, and critical process automation. Designed to interface directly with the Mark VIe I/O pack architecture, this module delivers reliable, deterministic digital output switching for demanding industrial environments.
Product Positioning: Procurement engineers sourcing replacement or expansion I/O for GE Mark VIe, EX2100e, or LM2500 control systems will find the IS220PDOAH1B to be a direct OEM-equivalent solution. Konmask.com supplies this module from verified surplus and refurbished channels, fully tested to factory specifications, with traceability documentation available on request.

Engineering Advantages
- Direct OEM Compatibility: Plug-and-play replacement within existing Mark VIe I/O pack chassis — no firmware modification required
- High Channel Density: 16 discrete outputs per module minimizes rack space and reduces total installed cost
- Deterministic Response: Synchronized with Mark VIe IONet for sub-millisecond output latency in turbine protection sequences
- Robust Isolation: Optical isolation on all output channels protects controller backplane from field-side transients
- Hot-Swap Capable: Supports live replacement in redundant Mark VIe configurations without process shutdown
- Wide Thermal Range: Rated for continuous operation in high-ambient turbine enclosures up to 60°C
System Architecture & Signal Flow
The IS220PDOAH1B installs into the Mark VIe I/O pack assembly and communicates via the proprietary IONet Ethernet-based I/O bus to the Mark VIe controller (VCMI/VCRC). The controller issues discrete output commands at each scan cycle; the module latches the output state and drives the field-side load through its solid-state switching elements. Each channel is individually addressable and status-monitored, with diagnostic feedback returned to the controller for fault annunciation. The module supports both simplex and TMR (Triple Modular Redundant) control architectures.

Technical FAQ
Q: Is the IS220PDOAH1B compatible with Mark VI (non-VIe) systems?
A: No. The IS220PDOAH1B is designed specifically for the Mark VIe I/O pack architecture. Mark VI systems use a different I/O bus and connector standard. Please confirm your controller generation before ordering.
Q: Can this module operate in a TMR (Triple Modular Redundant) configuration?
A: Yes. The IS220PDOAH1B supports both simplex and TMR Mark VIe architectures. In TMR mode, three modules vote on output state for fail-safe operation.
Q: What is the output current rating per channel?
A: Per GE Mark VIe I/O specifications, discrete output channels are rated for 24 VDC sourcing loads. Contact us for the specific current rating datasheet for your application.
Q: Do you provide a test report with each unit?
A: Yes. A functional test report is available upon request. Please specify at time of order.
Q: Can you supply multiple units for a plant-wide spares program?
A: Yes. Konmask.com supports bulk procurement for MRO spares programs. Contact us for volume pricing and consignment options.
