Product Overview

The General Electric DS3800NOAA1F is an extended analog I/O printed circuit board used in Speedtronic Mark IV turbine control systems for gas and steam turbine applications. It supports analog signal conditioning and interface functions required for turbine sequencing, control supervision, and auxiliary measurement tasks. The board is commonly used where stable analog handling and service-friendly diagnostics are needed inside legacy Mark IV control cabinets.

This PCB is designed for cabinet integration and includes features that help technicians with installation and field servicing, including extractor clips, test access points, and on-board status indication.
