Description
🔹 Product Description
The GE DS200UDSAG1A, with the detailed board identification DS200UDSAG1APR2, is an Excitation Board used in GE Mark V Speedtronic turbine control and excitation applications. The UDSA board contains an 80196 microprocessor, EPROM devices, a 40-pin interface, 21 four-character displays, 32 LED indicators, jumper switches, and other signal-processing circuitry. It exchanges signals with other boards and devices within the Mark V system and provides local diagnostic information through its displays and LEDs. The DS200UDSAG1APR2 is identified as a Group 1 UDSA configuration with multiple revision designations, so the complete board marking should be matched carefully when selecting a replacement.
