The BBSI234 is an isolating converter providing true 3-way galvanic isolation up to 2kV rms. The BBSI234 produces an isolated bipolar output signal from an input signal. The BBSI234 comes in three, coding plug selectable models to accept either Process, mV or Bipolar input signals. No special tools or components are required for range changing in the field. A 20Vdc/22mA sensor supply is available at the input section, this can be useful for loop powered field transmitters. The output drive circuit is factory configured to provide load independent voltage or current outputs. Final calibration is trimmed using the front accessible zero and span 15-turn trim adjustments. The wide swing DCpower supply (8-60V) covers all popular DC sources. All units are fitted with a 500ms filter that can be link changed to 5ms for fast response. Surge protection for power supply and input is standard with all BASI modules.
