Overview
The 5B Series perform single-channel analog signal conditioning for
National Instruments DAQ devices. These modules are fastened to an
8 or 16-channel backplane that is connected to the data acquisition
device, providing assorted signal conditioning on a channel-bychannel basis. The 5B Series provides isolation, noise rejection, and
amplification for millivolt sources, volt
sources, 4 to 20 mA sources, 0 to 20 mA
sources, RTDs, thermocouples, strain
gauges, potentiometer, and frequency
inputs. Analog voltage and current output
modules are also available.
