Mark VIeS YVIB Vibration Monitor I/O Pack
The YVIB vibration monitoring module contains a local processor and data
acquisition board, which are housed in an I/O pack. Either one or three I/O packs
can be mounted on the TVBA terminal board, to provide either Simplex or TMR
module redundancy. The TVBA provides two 24-point, barrier-type terminal
blocks that accept two 3.0 mm
2
(#12AWG) wires with 300 V insulation and
spade or ring type lugs.
Captive clamps are provided for terminating bare wires. Signal flow between the
terminal blocks and the I/O packs is conditioned with passive suppression
circuits and electromagnetic interference protection. In addition, a pull-up bias is
applied to signals for open circuit fault detection.
The YVIB can monitor 13 sensors, and has the flexibility to mix sensor types
based on specific channel configuration and YVIB processor type. The I/O pack
has two RJ-45 Ethernet connectors, one 3-pin power input, and a DC-37 pin
connector that connects directly to the TVBA terminal board. Visual diagnostics
are provided through indicator LEDs.
