FUNCTIONAL DESCRIPTION:

IS200TVIBH2BAA is a Vibration Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Turbine Control Systems. The Vibration Input (TVIB) terminal board accepts up to 14 vibration probes, two of which can be cabled directly to the VVIB board. VVIB processes and digitizes the displacement and velocity signals, which are then sent over the VME bus to the controller. The Mark* VI system uses Bently Nevada probes for shaft vibration monitoring. The following vibration probes are compatible with TVIB:

• Proximity
• Velocity
• Acceleration
• Seismic
• Phase

There are two types of TVIB terminal boards, H1A and H2A. The H2A type board has BNC connectors allowing portable vibration data gathering equipment to be plugged in for predictive maintenance purposes. Both types have connectors so that Bently Nevada vibration monitoring equipment can be permanently cabled to the terminal board to measure and analyze turbine vibration. In the Mark VI system, TVIB works with the VVIB processor and supports simplex and TMR applications. Two TVIBs connect to VVIB with two cables. In TMR systems, TVIB connects to three VVIB processors with three cables.

INSTALLATION:

Connect the wires for the 14 vibration probes to the two terminal blocks, three wires per probe. In simplex systems, connect the TVIB1 JR1 connector to VVIB J3 on the VME rack and the TVIB JR1 connector to VVIB J4. In TMR systems, connect the VVIB JR1, JS1, and JT1 connectors to the R, S, and T VVIBs. Use jumpers JP1 through JP8 to select the probe type for the first eight probes. Optionally, connect TVIB to a Bently Nevada system using connectors JA1, JB1, JC1, and JD1.

OPERATION:

TVIB supports Proximitor, Seismic, Accelerometer, and Velomitor probes supplied by Bently Nevada. Power for the vibration probes comes from the VVIB boards in simplex or TMR mode. The probe signals return to VVIB where they are A/D converted and sent over the VME bus to the controller. Vibration, eccentricity, axial position alarms, and trip logic are generated in the controller. A -28 V dc source is supplied to the terminal board from the VME board for Proximitor power. In TMR systems, a diode high-select circuit selects the highest - 28 V dc bus for redundancy. Regulators provide individual excitation sources, -23 to -26 V dc, that are short-circuit protected. VVIB samples the probe inputs at high speed over discrete periods.

FREQUENTLY ASKED QUESTIONS:

What is a Vibration Input Terminal Board?

A Vibration Input Terminal Board is a device used to interface vibration sensors with data acquisition systems or monitoring equipment. It typically includes connectors for attaching sensors and circuitry for conditioning the sensor signals before they are fed into the data acquisition system.

What types of sensors can be connected to a Vibration Input Terminal Board?

Vibration Input Terminal Boards can typically accommodate various types of vibration sensors, including accelerometers, velocity sensors, and displacement sensors.

What is the purpose of conditioning circuitry in a Vibration Input Terminal Board?

The conditioning circuitry in a Vibration Input Terminal Board is responsible for amplifying, filtering, and sometimes digitizing the sensor signals to ensure accurate and reliable measurements.
