The refractometer has an M12 connector in the refractometer for power supply, mA output and Ethernet connections.
PR‑43 refractometers are powered with 24 V DC. For more information on connecting the refractometer to Multichannel user interface MI, see Multichannel User Interface MI User Guide. For more information on connecting the refractometer to Compact user interface CI, see Compact User Interface CI User Guide. The following figure shows how to connect the M12 refractometer cable.
The PR‑43 refractometer provides both analog (mA) and digital output signals. The following figure shows the wiring when only analog output is used.
In split cables the power cable and the mA output cable are marked near the end of the cable.
