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 2B23J.
Both span and offset may be adjusted using optional external potentiometers.
Featuring wide range, single supply operation (+14V to + 28V dc), the 2B23 provides isolated loop power, thus eliminating the need for an external dc/dc converter.
In data acquisition and control systems, the 2B23 may act as an isolated interface between the D/A converter output of a microcomputer analog I/O and standard 4 to 20mA or 0 to 20mA analog loops.
In process control systems, the 2B23 may be used as a c...
