FUNCTIONAL DESCRIPTION:

IS230TVBAH6A is a Vibration Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The vibration terminal board (TVBA) acts as a signal interface board for the Mark VIe I/O pack PVIB. In the Mark VI system, the VVIB board works with TVIB. The TVBA provides a direct interface to seismic (velocity), Proximitors, Velomitors, and accelerometer-type probes. The terminal board provides signal suppression and electromagnetic interface (EMI) protection for each input signal. Signals are also connected to a pull-up bias to allow open circuit detection. The signals are passed on to the Mark VIe I/O packs through a 37-pin connector. The TVBA can be used for either simplex or TMR applications. TMR applications fan the signal to three I/O packs. The TVBA contains buffered outputs to additional connectors beyond the standard 37-pin connection. This feature allows special 9 and 25-pin connectors to feed the Bently Nevada® 3500 monitoring system. A bayonet nut connection (BNC) connection for each channel is also included with this feature, to feed other third-party monitoring equipment. Mark VIe systems do not use the traditional RKPS power supply.

INSTALLATION:

The TVBA accepts 14 sensor inputs that are wired directly to two I/O terminal blocks. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield termination attachment point is located adjacent to each terminal block.

Input Channels 1 through 8:

• Support Proximitors, Seismics, Accelerometers (channels 1,2, 3 only), and
  Velomitors
• Current-limited -24V power supply per channel
• JPxA jumper for configuring the open circuit check support and 3mA constant
  current feed for Velomitors
• JPxB configures the JA1 and JB1 outputs for the Bently Nevada 3500 rack
• JPxC configures PR0xL as Open for true differential input or connects PR0xL to
• PCOM for a -24 V return.

Input Channels 9 through 12:

• Support Proximitors sensors only
• Current-limited -24V power supply per channel
• No jumper configuration
• Input Channel 13:
• Support Proximitors or Keyphasor proximity sensors
• Current-limited -24V power supply per channel
• No jumper configurations

-28V power supply board, WNPS:

• Converts +28V from PVIB to -28V used by the current-limited -24V outputs
• One WNPS per PVIB
• Independent +28V inputs and common -28V bus for all three WNPSs

OPERATION:

The TVBA supports 14 sensor connections:

• Eight Vibration or position (ckts 1 through 8)
• Four Position only (ckts 9 through 12)
• One Reference probe (Keyphasor) or position, (ckts 13)
• One Reference probe (Keyphasor) or position, (ckt 14) (for Bently Nevada 3500
  interface only)

Keyphasor Inputs:

• Vibration Inputs accommodate the following transducers:
• Proximitor
• Seismic
• Velomiter
• Accelerometers (first three inputs on PVIB only)

BUFFERED OUTPUTS:

Each channel provides additional outputs other than the standard 37-pin connection. The signal output is a buffered version of the monitored signal. Each channel is output on a BNC connector. Each channel is also output through a 25-pin (Vib/Position) or 9-pin (Keyphasor) connector designed to interface with the Bently Nevada 3500 monitoring system. Requirements on the buffers are as follows:

• Amplitude accuracy 0.1%
• Add a -11 V dc, ± 5%, bias on seismic signals
• Sink 3 mA when interfacing with a Velomitors
• Unity-gain buffered output drives an impedance of 1500, capacitive up to
• 1000pF, with less than 10% overshoot.
