DS3800DMEA

Product Description

The DS3800DMEA is a printed circuit board manufactured by GE that integrates into their Speedtronic Mark IV series. This series was designed for fuel, air and emissions control, sequencing turbine fuel for startup, for monitoring the turbine's control and auxiliary functions, and for shutdown and cooldown procedures. As the Mark IV was intentionally designed with integrated boards with built-in redundancies, it can manage all of the above with minimal downtime caused by electronics failure.

The DS3800DMEA is designed as an exciter control board and has the following specifications:

• it is factory-drilled with six holes, one in each corner plus an extra in each left corner, top and bottom.

• it has a 50 pin male connector along the right long side. This is marked 218A4637P5

• it has eighteen jumpers that run down the center of the board. These run in the same line as nine test points.

• it has eleven TP rings. Nine of these run in line with the jumpers. The other two TP points are located in the bottom left corner of the board.

• it has one switch, labeled SW1

• it has eight LEDs that run along the left long side of the board. These are labeled from top to bottom, "Tach loss," "OS," "OV," "IOC," "IOL," "Field loss," "Alarm," and "Moving."

• it has fourteen round adjustable resistors, marked 0/50/100, with 10-point hashes. The resistors sit in two parallel lines of seven next to the LEDs. They are labeled (top to bottom, left to right) IE Cal, Field loss, Min fld, IA cal, IR comp, CMPD, %m/d, IOC Adj, Tol Adj, CEMF Cal, Overvolts, Spd Adj, Slo Spd, OverSpd.

• it has 8 screw terminals

• it has 8 diodes

• it has 21 ceramic, metal film resistors
