The Mark V system is designed to fulfill all gas turbine Control requirements.The Mark V control boards and control cards part numbers belong to the DS200 series.The Mark V Turbine control system uses digital microprocessors to control the Gas Turbine.

The Mark V Speedtronic Control system has a software Implemented Fault Tolerance to increase the reliability of the turbine control system.

The Mark V speedtronic DS200NATOG1A is a LCI Circuit Board.DS200NATOG1A is a Voltage Feedback Scaling Board (NATO) that regulates the voltages of an SCR bridge( AC &DC) so that the bridge voltages can be accurately derived.DS200NATOG1A works in conjunction with two other boards, a VME backplane and a gate distribution and status board.

The DS200NATOG1A has five identical,series of strings of precision resistors.Each string can be configured using a selection of input stab connectors and two wire jumpers to attenuate different volt inputs.The output of the five strings of DS200NATOG1A is connected to a single 20 pin ribbon header. A Metal Oxide Varistor (MOV) controls the high voltage on each string if the ribbon circuit is interrupted.The burden resistor is located on the gate distribution and status board.The resistors on this board are grouped in to five resistor strings denoted by letters A TO E.

The DS200NATOG1A is designed to meet the CSA/UL/EC standards for transients known and controlled.Always stick to the manufactures guidelines while installing the board.

Since the DS200 series is obsolete ,we suggest you have a shelf stock of minimum 2 cards of every panel including the DS200NATOG1A.
