IS200STAOH2AAA

The GE IS200STAOH2A is an industrial Status & Timing Output Handler (STAOH) module designed for use in GE EX2100 Excitation Control Systems and Mark VI Speedtronic turbine automation platforms. Its primary function is to aggregate, condition, and distribute status and timing-based output signals from the central controller to downstream logic, relay drivers, auxiliary devices, annunciators, and supervisory systems. This board ensures that critical status flags, event timing outputs, and logic transitions are communicated reliably and synchronously across the excitation and turbine control architecture.
