8.5.2.9 TVBAS2B Buffered Outputs

With the TVBAS2B, each channel provides additional outputs other than the standard 37-pin connection. The signal output is
buffered from the signal used by the I/O module to prevent any corruption caused by third-party hardware connected to the
output.
Each channel is output on a BNC connector with 10 kilo-ohms between the buffer out and BNC signal pin and 10 kilo-ohms
isolation between signal low and the control power common, PCOM.
Each channel is also output through a 25-pin or 9-pin connectors JA1, JB1, JC1 and JD1 designed to interface with the Bently
Nevada 3500 monitoring system. The TVBA buffered source impedance is approximately 40 ohms.
The jumper, JPxB where x = 1 through 14 is used to configure the output for either seismic outputs with a -11 V dc bias
voltage added to the velocity signal or positioned to output Proximitor, Velomitor or accelerometer with integrated output
signals.
