GE IS220YDIAS1A Product Specification
Product Overview
The GE IS220YDIAS1A is a high-reliability discrete contact input/output (I/O) module engineered for GE’s Mark VIe Speedtronic Turbine Control System, serving as a critical interface for industrial machinery monitoring and control. Designed to handle digital signals from switches, relays, and sensors, this module enables real-time command execution and status feedback in gas turbines, steam turbines, and other mission-critical equipment across power generation, oil and gas, and heavy manufacturing.
As part of the Mark VIe distributed control architecture, the GE IS220YDIAS1A supports 16 channels for simultaneous monitoring and control of discrete signals, with a nominal voltage rating of 28 VDC and compatibility with hazardous location applications (Class I, Division 2) . Its dual redundant 100 Mbps Ethernet ports ensure seamless communication with the Mark VIe controller, while the hot-swappable design allows module replacement without system downtime. The module’s rugged construction—featuring a triple-layer conformal coating and IP20-rated enclosure—ensures reliable operation in harsh environments with high vibration, humidity, and temperature fluctuations (-35°C to +65°C) .
In automation systems, the GE IS220YDIAS1A acts as the backbone for discrete control loops, providing critical data for turbine valve actuation, safety interlock monitoring, and alarm triggering. Its compatibility with IS200STCIS1A/2A and IS400STCIS1A/2A terminal boards allows deployment in explosive atmospheres, adhering to industry standards for safety and reliability .

Maintenance Recommendations:
Perform monthly visual inspections to confirm front-panel LEDs (Power, Ethernet Link, Fault) indicate normal operation. Clean dust from ventilation slots using compressed air to maintain cooling efficiency. Quarterly, use a multimeter to verify output voltage (28 VDC ±5%) and check terminal connections for corrosion. Annually, update firmware via GE’s Proficy software to access bug fixes and compatibility enhancements. Test redundancy by disconnecting one Ethernet port and confirming seamless switchover to the secondary channel .
