Connecting Analog Input Signals

You can connect up to four analog input signals (or IEPE sensors) to the BNC connectors on a
DT9837 Series module. Internally, these signals are connected in single-ended mode. The
DT9837 Series modules support an input signal range of ±10 V (using a gain of 1) or ±1 V
(using a gain of 10).
Note: If you enable the use of the internal excitation current source for IEPE inputs, it is
recommended that you choose AC coupling. Refer to
inputs.
