The DS200LDCCH1APA is a Drive Control and LAN Communications Board created by General Electric as part of their Mark V series. The Mark V is part of the successful Speedtronic line of gas and steam heavy-duty turbine management systems developed by GE. While the MKV is now considered obsolete and is no longer supported by the manufacturer, it is still in active use around the globe. The series uses triple redundant backups on protection parameters and critical controls to increase reliability. The DS200LDCCH1APA is able to function within exciters or drives that are a part of GE’s DIRECTO-MATIC family. The board provides primary drive functions and I/O control functions. The board is built with four microprocessor chips, including a drive control processor (DCP,) a motor control and co-motor control processor (MCP and CMP,) and a LAN control processor (LCP.) It also has six flash PROMS and an EEPROM that contains space for field-adjustable parameters.
The DS200LDCCH1APA is capable of processing Inputs/Outputs through its LAN control processor from five different bus systems. These include C-bus, CPL, Genius bus, DLAN, and DLAN+. Since some of these bus systems need a separate interface board to complete I/O transfer, the DS200LDCCH1APA is designed to connect to an auxiliary board, which mounts to four standoffs located in the upper right quadrant of the board. All ten I/O connections located on the DS200LDCCH1APA are vertically mounted. Ten connections are male. One is female.
The DS200LDCCH1APA has fourteen wire jumpers and ten Berg-type jumpers. There are eight TP test points located on the board. The board is built with a sixteen character operator interface module, which is located in the upper left quadrant. This interface allows the user to do diagnostic testing and to make software adjustments. The board includes a ten-light LED strip which can be programmed to indicate drive variables and/or fault codes.
