Turbine Control Output Solution – GE IS220YDOAS1AJ | Mark VI Speedtronic Series
Where This Product Is Used
The GE IS220YDOAS1AJ Discrete Output Pack Module is a critical I/O component deployed in GE Mark VI Speedtronic turbine control systems. Engineers and plant operators rely on this module across a wide range of industrial power generation and process control environments, including:
- Gas turbine power plants — controlling actuators, solenoid valves, and relay outputs for fuel control and auxiliary systems
- Steam turbine facilities — managing discrete output signals for trip circuits, bypass valves, and lube oil systems
- Combined-cycle (CCGT) plants — coordinating output signals between gas and steam turbine control loops
- Compressor stations — driving discrete outputs for anti-surge valves and shutdown logic
- Offshore oil & gas platforms — providing reliable discrete output control in harsh, vibration-prone environments
- Industrial cogeneration systems — interfacing with plant DCS for coordinated output control

Application-Specific FAQ
Q: Is IS220YDOAS1AJ compatible with both Mark VI and Mark VIe systems?
A: The IS220YDOAS1AJ is primarily designed for the Mark VI platform. Mark VIe compatibility depends on the specific I/O pack revision and rack configuration — contact our technical team to confirm interoperability for your application.
Q: Can this module be used in a TMR (Triple Modular Redundancy) configuration?
A: Yes. The YDOA pack is compatible with TMR Mark VI architectures. Ensure all three redundant slots are populated with matching revision modules for proper voting logic operation.
Q: What is the lead time for IS220YDOAS1AJ?
A: In-stock units ship within 3–5 business days internationally. For urgent outage recovery, contact us directly for expedited options.
Q: Do you provide a test report with the module?
A: Yes. A functional test report is available upon request for refurbished units. New surplus units include original OEM documentation where available.
Q: Can Konmask source other IS220 series modules?
A: Yes. We stock a broad range of IS220 and IS215 series Mark VI I/O modules. Submit your full parts list for a consolidated quote.
