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.
