FUNCTIONAL DESCRIPTION:

IS200TSVOH1BAA is a Servo I/O Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Servo Input/Output (TSVO) terminal board interfaces with two electro-hydraulic servo valves that actuate the steam/fuel valves. Valve position is measured with LVDTs. Two cables connect to VSVO using the J5 plug on the front of VSVO and the J3 or J4 connector on the VME rack. TSVO provides simplex signals through the JR1 connector, and fans out TMR signals to the JR1, JS1, and JT1 connectors. Plugs JD1 or JD2 are for an external trip from the protection module.

INSTALLATION:

Connect the wires for the sensors and servo valves directly to two I/O terminal blocks on the terminal board, as displayed in the figure Servo Terminal Board Wiring. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wiring. A shield termination strip attached to the chassis ground is located immediately to the left of each terminal block. Connect the wires for the external trip into JD1 or JD2. Cable the J5 connectors to the front of VSVO boards in racks R, S, and T. Cable the J1 connectors to the VME rack below VSVO in R, S, and T.

OPERATION:

VSVO provides four channels consisting of bi-directional servo current outputs, LVDT position feedback, LVDT excitation, and pulse rate flow inputs. The TSVO provides excitation for and accepts inputs from, up to six LVDT valve position inputs. There is a choice of one, two, three, or four LVDTs for each servo control loop. If three inputs are used they are available for gas turbine flow measuring applications. These signals come through TSVO and go directly to the VSVO board front at J5. Each servo output is equipped with an individual suicide relay under firmware control that shorts the VSVO output signal to signal common when de-energized and recovers to nominal limits after a manual reset command is issued. Diagnostics monitor the output status of each servo voltage, current, and suicide relay.
