IS200TVBAH2ACC Vibration input terminal board GE

Description

IS200TVBAH2A is a Vibration Input Terminal Board and is part of the GE Speedtronic Mark VIe gas turbine control system. The PVIB / YVIB I/O pack uses the Vibration Input (TVBA) terminal board as a signal interface board. Seismic (velocity), Proximitors, Velomitors, and accelerometer-type probes can all directly connect with the TVBA. For each input signal, the terminal board offers electromagnetic interface (EMI) protection and signal suppression. To enable open circuit identification, signals are additionally coupled to a pull-up bias. Through a 37-pin connector, the signals are sent to the I/O packs.

IS200TVBAH2A Functional Description
You can utilize the component for simplex or TMR applications. Three I/O packs are fanning the signal using TMR applications. The TVBA contains buffered outputs to additional connectors beyond the conventional 37-pin connection. This feature enables the Bently Nevada 3500 monitoring system to be powered via specific 9 and 25 pin connectors. This feature also includes a bayonet nut connection (BNC) connection for each channel to feed other third-party monitoring apparatus. Mark RKPS power supply are not used by VIe/VIeS control systems.
There is no external source of -28 V electricity; power is acquired from sourced +28 V power supplies.
The module features three detachable daughterboards to convert +28 to -28 as a result. All negative power used by the TVBA comes from these WNPS (negative power supply) boards.
