494.16 VD/DUC This card includes a digital universal conditioner (DUC)
(upper RJ-50 connector–JXA) and a valve driver (lower
RJ-50 connector–JXB).
The conditioner portion of this card is identical to the
conditioners in the Model 494.26 Card.
With a 2-stage servovalve, you can configure this card to
provide a DUC for “active mode” feedback (or an
auxiliary input) while the valve driver provides the drive
signal for a Series 252 Servovalve.
With a 3-stage servovalve, the DUC is reserved for the
valve LVDT feedback while the valve driver provides the
drive signal for a Series 256 or 257 Servovalve.
Not required
494.21 DUC/
Accelerometer This card combines a multi-range digital universal
conditioner (DUC) input and an accelerometer
compensation input on a single card. The summing of the
two signals is performed on the card based on software
settings.
Note You can also use this card as a stand-alone
multi-range DUC without an accelerometer
input.
Not required
494.25 Single DUC This card has one digital universal conditioner (DUC) that
you can configure as either an AC conditioner or a DC
conditioner. The conditioner uses a single, front-panel
RJ-50 connector (JXA) on the I/O carrier board. The
lower connector (JXB) is inactive.
The AC configuration is typically used to condition an
LVDT. The DC configuration contains circuitry that
supports 1/4-, 1/2-, and full-bridge transducers.
The configuration and setup of this card is identical to the
Model 494.26 Dual DUC card.
