The IS200TTURH1C is a termination board from General Electric. This board is designed to be compatible with the company’s later Speedtronic systems. This includes the Mark VI as well as the Mark VIe systems. AX Control maintains on-hand, ready-to-ship stock for both of these systems, along with components for earlier Speedtronic systems. Speedtronic systems have progressively become more complex since the earliest iteration (Mark I) became available for industrial gas and steam turbine management in the late 1960s.
The IS200TTURH1C is primarily rectangular, with a few small cutouts. The board is used together with other PCBs like the PTUR and VTUR boards to control the synchronization of the generator. This is done primarily through hardware and connections.
The IS200TTURH1C has several surface-mounted relays. Additionally, the board uses variable resistors and also has two transformers located near the center of the board. Communication with other board components occurs through d-shell connectors (both male and female), plug connectors, and terminal blocks. The largest two terminal blocks on the board have screw-mounted connectors that are numbered for reference.
The IS200TTURH1C also includes two jumper switches that allow the board circuits to be changed to allow either simplex or TMR voting.
