The Signal Isolator BSI282 is an isolating converter providing true 3-way galvanic isolation up to 2kV rms The BSI282 produces an isolated unipolar output signal from an input signal. The BSI282 comes in four, coding plug selectable models to accept either: Process, mV, Bipolar or Bipolar mV 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. Final calibration is trimmed using the front accessible zero and span 15-turn trim adjustments. Maximum current drive is 20mA and maximum voltage drive is 20V. The wide swing ac/dc power supply’s cover all popular requirements. All units are fitted with a 500msec filter that can be link changed to 5 or 50msec for fast response. Surge protection for power supply and input is standard with all BASI modules.
