Product Description

The DS200STCAG1A is a Turbine Communication Board. This board was initially created by GE for the Speedtronic Mark V LM series of control panel hardware. This board is not being supported by GE anymore and is a little hard to find. Please consult AX Control for the availability of the DS200STCAG1A.

The DS200STCAG1A, as a turbine communication board (STCA), has the ability to be an IONET specific master for the I/O cores in the <R> core. This board has hardware that does need to be configured once it has been installed. There is a JP2 jumper that can allow the board to be factory tested. Jumper JP4 has the ability to use the flash EPROM to select the voltage that the device needs. There is software that also needs to be configured for this board. On the operator interface, the I/O configuration of the compressor stall, the pulse rate constants, and the synchronization settings all need to be set.

Within the Mark V turbine control enclosure cabinet, the DS200STCAG1A is typically mounted at the top with the other I/O control boards. It is normally mounted in the top slot with four other boards that can be one of the following: TCCA, TCQA, TCQC, TCQE, TCPS, TCPS, TCCA, or a TCCB. Within an enclosure cabinet, there can be four different I/O control sections for a maximum of four STCA boards.  

The DS200STCAG1A contains a pulse rate input circuit and a synch check circuit. The pulse rate circuit has the ability to read the pulse rate inputs that are coming from the TCQC board and then scale and condition those readings. The synch check circuit has the ability to check the synchronization on the STCA board and then pass that information to the TCTG board. Once the TCTG board has that information it can then use it with additional information to create generator breaker commands.
