Turbine Control Digital Input Solution – GE IS220YDIAS1A | Mark VIe Series
Where This Product Is Used
The GE IS220YDIAS1A is a Simplex Digital Input (DI) module engineered for GE’s Mark VIe Turbine Control System. It is deployed across a wide range of critical industrial environments:
- Gas & Steam Turbine Power Plants — monitoring discrete signals from inlet guide vanes, bleed valves, and trip solenoids
- Combined Cycle Power Generation — integrating field contact status into the Mark VIe controller for real-time protection logic
- Compressor Stations & Pipeline Control — capturing limit switch, pressure switch, and emergency shutdown (ESD) contact inputs
- Offshore Oil & Gas Platforms — reading discrete field signals in hazardous-area turbine packages
- Industrial Cogeneration Facilities — interfacing with motor control center (MCC) status contacts and breaker auxiliary contacts

Why Engineers Specify This Model
- Simplex architecture — cost-effective single-channel DI solution for non-safety-critical discrete monitoring points
- IONet plug-and-play — hot-swappable I/O pack design minimizes downtime during replacement or commissioning
- High channel density — 24 inputs per module reduces panel footprint and wiring complexity
- Seamless Mark VIe integration — native compatibility with VCMI, VCRC, and VCCC controllers; no additional gateways required
- Proven field reliability — widely deployed in GE Frame 6B, 7E, 7F, and 9E turbine packages globally
- Toolbox-configurable — channel assignment and filtering configured via GE Mark VIe Toolbox software without hardware jumpers

Application-Specific FAQ
Q: Is the IS220YDIAS1A compatible with Mark VI (non-VIe) systems?
A: No. The IS220YDIAS1A uses the IONet Ethernet-based bus exclusive to Mark VIe. Mark VI systems use a different I/O bus architecture and require IS200-series modules.
Q: Can this module be used in a TMR (Triple Modular Redundant) configuration?
A: The YDIAS1A is a Simplex (S) module. For TMR applications, GE offers the IS220YDIAT1A (TMR variant). Confirm your system’s redundancy requirement before ordering.
Q: What is the maximum cable length from field device to terminal board?
A: GE recommends a maximum of 300 m (1,000 ft) for 24 VDC discrete input wiring, subject to cable resistance and noise environment.
Q: Do you provide a warranty?
A: Yes. Konmask.com offers a 90-day functional warranty on all tested units. Extended warranty options are available — contact us for details.
Q: Can I get a datasheet or GE part documentation?
A: Yes. Email support@konmask.com with your inquiry and we will provide available GE technical documentation.
