GE IS230STAOH2A Mark VIe Analog Output Module
Product Overview
The GE IS230STAOH2A is a high-performance analog output module designed for mission-critical applications in GE’s Mark VIe distributed control system. Engineered for precision and reliability, this module serves as a vital component in industrial automation, particularly in power generation, oil & gas, and heavy manufacturing sectors. As part of the IS230 Series, the IS230STAOH2A converts digital control signals from the Mark VIe controller into analog outputs (4–20 mA or 0–10 V) to drive actuators, valves, and other field devices, ensuring seamless integration with turbine control systems, generator excitation systems, and process automation workflows.
Featuring 16 isolated analog output channels, the GE IS230STAOH2A delivers stable and accurate signal conditioning, even in electrically noisy environments. Its galvanic isolation (2,500 Vrms) protects the control system from voltage spikes and ground loops, while the DIN-rail mounting design simplifies installation in compact control cabinets. The module’s front-panel LED indicators provide real-time feedback on channel status, power supply health, and fault conditions, enabling rapid diagnostics and minimizing downtime.
In the Mark VIe ecosystem, the IS230STAOH2A interfaces directly with controllers like the IS220UCSAH1A and communication modules such as the IS220VCMIH2CA, forming a robust control loop. Its hot-swappable design allows for module replacement without system shutdown, a critical feature for 24/7 operations in power plants and refineries. By combining high-channel density, rugged construction, and advanced signal processing, the IS230STAOH2A ensures precise control and monitoring of industrial processes, enhancing operational efficiency and reducing maintenance costs.
