Connecting Analog Input Signals

For the DT9857-08 and DT9857E-08 modules, you can connect up to eight analog input signals
(or IEPE sensors) to the BNC connectors on the module. For the DT9857-16 and DT9857E-16
modules, you can connect up to 16 analog input signals (or IEPE sensors) to the BNC
connectors on the module. Internally, these signals are connected in single-ended mode. The
DT9857 and DT9857E 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.
