DS3800HXCA

Product Description

General Electric manufactured the DS3800HXCA as a component in their Speedtronic Mark IV series. A gas and steam turbine control system, the Mark IV has been designed using 'controlled failure' technology that harnesses the use of integrated chipsets with built-in intentional redundancies to avoid downtime caused by electronics failure. The Mark IV can be used to sequence turbines and their auxiliaries for start-up, for shutdown and cool-down procedures, and to protect the system against unsafe operating conditions.

The DS3800HXCA has been created to function as a shift register board and has the following specs:

• It is factory-drilled at all four corners

• It is populated on the left short edge with a female connector. This is marked 218A4553-1 AMP 533002-1 8705 front.

• It is alignment-marked (A through J) on one edge.

• It has five LEDs on its right short edge. These include one amber LED (Imok) and four red (Local, Bus, Chan, and Active.)

• It has five relay networks

• It has seven jumper switches. Five of these sit in-line; two sit separately. J7 sits separate, and has the option between "5.5mHz" and "11mHz."

• It has three TP test points situated next to the LEDs

• It has spare PTH (plated through holes) located near its upper right corner.

The DS3800HXCA is designed with multiple integrated circuits including oscillators, EPROMs, and DIP components. Most resistors are ceramic covered metallic film. Capacitors are usually smaller, silver or teal in color.

Installation procedures for the DS3800HXCA can be found in data sheets and manuals published by GE, which provided technical support for this component and others in the Mark IV line.
