Description
🔹 Product Description
The GE General Electric IS200VAICH1D is a VAIC VME Analog Input/Output Card designed for the GE Mark VI Speedtronic turbine control system. The board processes analog signals between field terminal boards and the Mark VI VME control rack, converting incoming analog signals to digital data for controller processing and converting output data back to analog signals for field circuits. The IS200VAICH1D is associated with the IS200VAICH1DAA designation and uses compatible TBAI/STAI terminal-board configurations. The D-rated functional revision is part of the VAIC board family, and the exact terminal-board arrangement should be confirmed before replacement.
