The input stage of the 2B23 may be single resistor programmed to accept voltages within a 0 to +10V range (+0.1V to +10V full scale). The isolated output is pin programmable to provide current in the range of 4 to 20mA or 0 to 20mA and can be operated with 0 to 800 Ω grounded or floating loads. The 2B23 uses reliable transformer isolation techniques and is available in two accuracy selections offering guaranteed non-linearity error (2B23K: ± 0.05% max, 2B23J: ± 0.1% max) and guaranteed low span drift (2B23K: ±0.005%/°C max, 2B23J: ±0.01%/°C max). The internally trimmed span and offset errors are ±0.1% for the 2B23K and ±0.25% for the ...
