Description
🔹 Product Description
The GE General Electric DS3800NRCA1D1C is a Mark IV DS3800 Resolver Board / input circuit board used in GE SPEEDTRONIC turbine control systems. The DS3800 Mark IV platform was developed for automated monitoring and control of gas and steam turbine systems. The NRCA board is identified in technical references as a GE Mark IV input card, while the supplied product designation identifies it specifically as a Resolver Board.
The board includes configurable jumper circuitry, test points, LED indicators, a trim potentiometer, and board-to-board connectors. Technical documentation identifies 20 jumper switches, seven test points, three red LEDs, two mating connectors, a transformer, resistor networks, a transistor, and several amplifier and logic circuits. These features support configuration, signal conditioning, monitoring, and interface functions within compatible legacy GE turbine control hardware.
