DS3800DGRD is an auxiliary card produced General Electric of the Speedtronic Mark IV series of turbine controls

Product Description
The DS3800DGRD is an auxiliary card produced by General Electric as part of the Speedtronic Mark IV series of turbine controls.

The circuit board has large 100 volt cylindrical yellow capacitors, as well as medium cylindrical yellow capacitors marked with 7081A and small 80 volt cylindrical yellow capacitors. On one half of the circuit board are twenty-seven (27) black potentiometers. Potentiometers are variable resistors which are typically marked with the minimum and maximum values in Ohms. The auxiliary card features multiple jumper pins which have blue jumpers. On the board are many striped resistors and diodes in various colors as well as many solid-colored resistors and diodes. The auxiliary circuit board features two connector ports which are black on the edge of the board. The board has on red switch as well as one black switch between the connector ports. The board has several test points lined up next to the jumpers. On one half of the circuit board are many gold square capacitors.

The Speedtronic Mark IV Control System developed from its predecessors, the Mark I and Mark II systems. Those earlier systems were founded on the automation of turbine control techniques, as well as sequencing and turbine protection techniques that came about in the 1940s. The Mark IV system is the product of over half a century of the creation and refinement of new technologies. The Mark IV system was developed for the fulfillment of all requirements for controlling a turbine including controlling fuels within the requirements of speed and load control.

The DS3800DGRC1E1C auxiliary card will be shipped to the user in a bag which will dissipate any static electricity prior to operation in order to protect the user.

Product Description

The DS3800DBIB is a small printed circuit board (PCB) designed as part of the Speedtronic (Mark IV) line manufactured by GE. The Speedtronic system is designed to sequence turbine fuel and to sequence turbine systems and their auxiliaries for startup. The Mark IV system is designed with a distributed control system which runs on an array of interconnected microprocessors. When one section of this gridwork fails, turbines will continue to work under the control of other parts of the system. In this way downtime is limited. The DS3800DBIB is designed specifically as an interface board.

The DS3800DBIB is a small daughterboard that works as a plug-in to another, larger PCB. It has been drilled out at the factory, one hole in each corner of the board. This board also has four connectors numbered 1 through 4. It has two small screw mounts covered by black tabs. The first mount is marked C101 and is positioned next to a ring marked TP1. The second is not marked and positioned next to a ring marked TP2. The DS3800DBIB has one capacitor rated 708A1, M/E 200V 1.0 +10%. It also has one blue potentiometer located on the edge of the board that is wired for variable resistance. There are ten resistors and six small capacitors marked 'cr' on the DS3800DBIB PCB
