Digital Universal Conditioner (DUC) Features
You can configure a DUC as either an AC conditioner or a DC conditioner.
General
•
Software-configurable conditioner gains allows the use of a wide range
of transducers.
•
Each DUC channel has its own indicator LED (located on the I/O
carrier board).
•
The conditioner includes a IEEE 1451.4, Class 2 smart transducer
interface.
•
A high-frequency input filter helps protect against ESD and EMI
interference.
•
An analog anti-aliasing filter is provided before the A-to-D converter.
•
The conditioner includes programmable digital filters.
Excitation
•
In DC mode, an excitation-sense circuit helps compensate for IR line
losses by boosting the DC excitation voltage when necessary.
•
Excitation under- and over-current detection is available for all
configurations. A system interlock is generated if an excitation fault is
detected.
•
The AC conditioner supports multiple, software-configurable excitation
frequencies
.
DC configuration
•
The DC conditioner supports quarter-, half-, and full-bridge
transducers.
•
The quarter-bridge DC conditioner supports the use of a customer-
supplied bridge-completion resistor that you install on the I/O carrier
board and bridge-completion circuitry on the DUC.
•
The half-bridge DC conditioner uses a bridge-completion circuit
located on the conditioner.
•
Software configuration allows you to apply a shunt resistor (installed
on the I/O carrier board) to the selected leg of the bridge.
