Isolated Analog Signal Conditioners interface to DC LVDTs.
Press Release Summary:
August 9, 2012 - Featuring 10 modules with input ranges from -1 to +1 V through -5 to +5 V, Series 8B43 isolates, filters, and amplifies voltage input signal, then provides analog voltage output. Modules interface to DC LVDTs which operate on 10 V excitation voltage and up to 20 mA of excitation current. Housed in miniature 1.11 x 1.65 x 0.4 in. package, signal conditioners provide ±0.05% accuracy, ±0.02% linearity, 1,500 Vrms transformer isolation, and continuous input protection to 240 Vac.

Mix and Match Module Types on Backpanel Signal filtering in the 8B43 is achieved with a 5-pole filter that is optimized for time and frequency response and provides 100dB per decade of normal-mode rejection above 1kHz. One pole of the filter is on the field side of the isolation barrier for anti-aliasing; the other four are on the system side. A special input circuit provides protection against accidental connection of power-line voltages up to 240VAC, while clamp circuits on the I/O and power terminals protect against harmful transients. Isolation is provided by transformer coupling to suppress transmission of common mode spikes or surges. The module is powered from +5VDC, 5%. Designed for installation in Class I, Division 2, hazardous locations, the 8B43 offers a high level of immunity to environmental noise.
