Product Description

The DS200TCEBG1ACD is a protective termination expander card from General Electric.  This board component is part of the company’s Mark V Speedtronic turbine control system.  General Electric began producing Speedtronic systems in the 1960s with the Mark I turbine control system.  AX Control works to maintain on-hand, ready-to-ship stock of replacement parts for all General Electric Speedtronic systems. 

The DS200TCEBG1ACD is built with four signal transformers, a 26-pin connector, and four ten-pin connectors.  The board also has three 20-pin connectors.   The board includes eight factory drilled holes to offer installation options. 

The DS200TCEBG1ACD is mounted within the <P1> core.  The board is used to scale CT and PT signals that are then used by the TCCB card located in the <R5> core.   Some signals, like the 335 VDC signals required for flame detector devices, are conditioned on this board and then are sent to the PTBA  terminal board.  The board also reads and passes through magnetic pick-up signals for emergency Overspeed that originate in the PTBA and send them to the TCEA board.    Additionally, this board holds the Mark V LM’s alarm horn. 

The DS200TCEBG1ACD does not include any jumper pins.  However, the alarm horn on the DS200TCEBG1ACD can be configured using a jumper located on the PTBA PCB.
