The DS3800XAIG was produced by GE (General Electric) for the Mark IV (MKIV) system. This system was designed for turbine control in gas and steam turbines. The Mark IV is a part of the Mark series. The first Mark series, Mark I, was first introduced in the late 1960s. The Mark systems are in control of all of the functions of turbines including fuel regulation, startup and shutdown, temperature regulation, troubleshooting, and many other auxiliary functions. The Mark IV controls fuel, air, and emissions. The Mark turbine systems are based on techniques which have been refined since the late 1940s. These technologies have grown and been developed for decades. The Mark IV utilizes technologies which were state of the art. The Mark system also protects both the turbine and the turbine’s operators from harm.
The DS3800XAIG is an analog interface circuit board. This PCB is small in size and only has a few components. The DS3800XAIG has five (5) long components covering most of the board. Three (3) of these large components are covered in black plastic. The other two (2) are made of gold metal. Each of the long components is labeled with the letters TB. Three (3) light blue jack connector ports are lined up on the edge of the DS3800XAIG. These connector ports feature male connector pins. A series of very small capacitors are arranged in a line on one edge of the DS3800XAIG. These capacitors are solid greenish-blue in color. Arranged next to these capacitors, there is a series of small banded resistors.
