Product Description
The GE IS420YDOAS1B is a Discrete Output I/O Module engineered for the Mark VIe and Mark VIeS control systems. It delivers precise and reliable control of relays, solenoids, and contactors, making it a key component in turbine shutdown systems, alarm annunciation, and interlock logic.
This output module features 12 relay channels, each equipped with coil monitoring and contact continuity verification to ensure operational safety. An integrated diagnostic processor continuously supervises output status and fault conditions, helping reduce downtime and improve system integrity.
Moreover, the IS420YDOAS1B supports Simplex and TMR (Triple Modular Redundant) configurations, allowing flexibility in both standard and high-reliability control environments. Its rugged design, fast 6-millisecond response time, and SIL-certified safety compliance make it suitable for critical industrial applications such as gas and steam turbine control.
