Description
GE IS230STAOH2A – Analog Output Terminal Board
GE IS230STAOH2A is a high-density analog output terminal board for GE’s Mark VIe turbine control systems, providing field wiring interface for I/O packs like SNAOH2A. This module supports 16 channels of 4-20 mA outputs with isolated screw terminals, delivering precise actuator control for valves, dampers, and variable frequency drives in gas turbine applications. It addresses signal distribution challenges by offering transient protection, short-circuit detection, and compatibility with simplex or TMR configurations, ensuring reliable command execution under demanding electrical conditions. The GE IS230STAOH2A mounts on DIN rails with removable connectors for simplified maintenance in control cabinets.
