GE IS220PDOAH1A Discrete Output Module – Mark VIe Control System Series
When a discrete output module fails in a gas turbine or steam turbine control system, the consequences are immediate and severe: actuators lose command signals, safety interlocks go blind, and the entire turbine unit may trip offline — costing operators tens of thousands of dollars per hour in lost generation capacity. In critical power generation and industrial process environments, there is no acceptable substitute for a verified, specification-matched replacement module. The GE IS220PDOAH1A is that replacement.
The IS220PDOAH1A occupies a pivotal role within GE’s Mark VIe distributed control architecture — one of the most widely deployed turbine control platforms in the global power generation industry. As a high-density discrete output board, it provides the hardwired command interface between the Mark VIe controller and field devices such as solenoid valves, relays, and motor starters. With Mark VIe installations spanning gas turbines, steam turbines, wind turbines, and combined-cycle plants across six continents, the IS220PDOAH1A represents a mission-critical component in the backbone of global energy infrastructure.

Frequently Asked Questions
Q: Is the IS220PDOAH1A a new or refurbished module?
A: Konmask.com offers both new surplus and professionally refurbished units. The condition is clearly stated in your quotation. All refurbished units pass our functional test protocol before shipment.
Q: Can this module be used as a direct replacement without reprogramming the Mark VIe controller?
A: In most cases, yes — the IS220PDOAH1A is a hardware-compatible replacement within the same Mark VIe I/O family. However, we recommend verifying the hardware revision (H1A suffix) matches your existing installation. Contact us for compatibility confirmation.
Q: What is the lead time for the IS220PDOAH1A?
A: Lead time depends on current stock levels. In-stock units typically ship within 3–5 business days internationally. For urgent plant shutdowns, contact us directly for expedited options.
Q: Do you provide a warranty?
A: Yes. All modules carry a 90-day functional warranty. Extended warranty options may be available — please inquire at the time of quotation.
Q: Can you supply multiple units or a full Mark VIe I/O rack?
A: Yes. We regularly fulfill multi-unit orders and complete rack assemblies. Volume pricing is available for quantities of 3 or more units.
Q: What payment and shipping methods do you accept?
A: We accept T/T (bank wire transfer) and other methods by arrangement. We ship via DHL Express, FedEx International, and sea freight for bulk orders.
