Model 483C30 offers 8 channels with true galvanic isolation of each input to output, x0.1–x200 incremental gain, 4-order 10 kHz low pass filter, and Ethernet interface. Model 481A03 has 16 channels of ICP inputs with programmable 8-order elliptical low pass filters, x0.0025–x200 incremental gain, and RS232 interface.Offered with selectable filters or isolated grounds, rack-mount models suit applications where case ground piezoelectric sensors are used and could cause ground-loop noise.
