Excitation Failure
Interlocks An over- or under-current condition generates a
system interlock.
AC/DC over current: 105 mA typical
AC/DC under current: 1–2 mA typical
Note Undercurrent detection may not work
properly for AC transducers with a DC
resistance greater than 180 ohms. In this
instance, the detection circuit may
constantly report an undercurrent condition.
You may need to configure your controller
software to disable the Excitation Failure
interlock for that input.
Excitation Failure interlocks are available for
quarter-, half-, and full-bridge DC configurations and
for AC configurations.

*. The DC gain accuracy specification includes the effects of linearity
and resolution.
†. DC mV/V (ratio-metric) accuracy specifications apply in 8-wire mode
only.
‡. The DC excitation accuracy and loading specifications apply in 8-
Wire Mode only.
§. The effects of cable length, transducer impedance, and associated
voltage drop are additional.
#. Excitation loading variability applies for resistive loading.
