Figure 35. Synchro or Resolver/Direct Input Signal Configuration
The Synchro or Resolver/Direct input options are created by factory
installation of thin-film resistor networks within socket locations on the card
(refer to
Figure 35
).
Table 5
lists the resistor network and location for each
input option.

Linear / Rotary Variable Differential Transformer (LVDT / RVDT)
The SB-3621XIX can also be used for a linear or rotary variable differential
transformer (LVDT or RVDT). When using the LVDT option (SB-36219IX),
the scaling resistors must be installed by the user (see
Figure 36
,
Figure 37
,
and
Figure 38
). Refer to
Figure 36
for component header installation. The op
amps shown in
Figure 37
and
Figure 38
are already installed on card.
This card uses the RD-19230 converter. For detailed LVDT scaling
information see the RD-19230 data sheet available on the DDC Web site
library (
).
