DS3800HLOC1A1B

Product Description

The DS3800HLOC1A1B is a board component for the Mark IV Speedtronic system from General Electric.  The Mark IV is one of several gas and steam control systems distributed by General Electric under the Speedtronic name since the late 1960s, and the first to offer microprocessor control and TMR (triple modular redundant) design.  The MKIV offered digital calculations and RS-232 or RS-485 transmission of data. 

The DS3800HLOC1A1B is a Logic Output board.  It is designed with a front edge that is populated by multiple light-emitting diodes positioned together in a line.  These include one yellow LED and sixteen red LEDs.  Next to this line of diodes is a switch component.  These are flanked on either side by extractor clips inserted into factory-made drill holes.  Extractors allow technicians to more easily extract a board from its location in the rack.  It also gives them something to hold on to--a handle--whenever it is necessary to touch the board. 

The DS3800HLOC1A1B is stiffened in both directions by multiple board stiffeners.   Between these, the DS3800HLOC1A1B is populated by integrated circuits, diodes, resistors, and capacitors made from various materials.  Most components are marked with reference designations.  The board is marked with the GE logo and with its board ID number.  The rear edge of the board is populated by a single backplane connector.  This allows the board to easily communicate with the rest of the rack and the rest of the Mark IV system.
