DS3800NERA1P1D General Electric Analog Microprocessor Board

Overview

The DS3800NERA1P1D is an analog microprocessor control board manufactured by General Electric (GE) as part of the DS3800 family of printed circuit

boards used in Mark IV and Speedtronic turbine control systems. These boards are components of legacy GE turbine automation systems,

where they perform signal processing and control logic tasks within the control rack.The DS3800NERAxx series designation

identifies boards involved in analog/processor functions, often responsible for reading analog inputs from sensors (e.g.,

vibration, temperature, speed), processing the signals with embedded microprocessor logic, and communicating

results to the control system. Although specific technical specs for “NERA1P1D” are not widely

published online, its role parallels other DS3800 analog and

processor cards in GE’s legacy turbine controllers.
