The BSSP235 is an isolating converter providing true 4-way galvanic isolation up to 2kV rms. The BSSP235 produces two isolated unipolar output signals from one input signal. The BSSP235 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. 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. Both outputs are isolated from each other. The wide swing DC-power 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.
