The DS3815PCLA1D1D is a communications assembly card created by GE for the MKIV series. This series, which manages gas and steam turbines, is built with distributed control functions built across multiple microcomputers which monitor the turbine system continuously. These systems help improve the Mark IV’s dependability and lower the turbine outage rate compared to older systems like the MKI and MKII.
The DS3815PCLA1D1D is marked on the top edge for alignment. It is drilled at each corner and has extractor clips installed. The board communicates with other PCBs via two Augat connectors and three PCB mating connectors, including two right-angled male connectors.
The DS3815PCLA1D1D has two test points, which are labeled COM and TST. The board has three LEDs (light emitting diodes.) These are placed on the right edge and include one amber LED and two red. The board is marked with the codes 6DA02 and 6BA06.
The DS3815PCLA1D1D has five resistor networks and eighteen jumper switches. Jumpers are placed in several places on the board. Some have the option of being set to zero or to one. Others allow the user to choose from IN or OUT, INT or EXT, or 2K or 4K. The board primarily uses ceramic-covered metal film resistors and fixed vacuum capacitors. Resistors and capacitors of other material can be found on the board.
The DS3815PCLA1D1D has sixty circuits. Included in this count are 8-bit CMOS static RAM with fast access time (150ns) and low power standby. The board also has buffers/line drivers employed as clock drivers, memory-address drivers, and bus-oriented transmitters/receivers.
All tech support for the DS3815PCLA1D1D (including manuals) was provided by GE.
