The refractometer has an M12 connector in the refractometer for power supply, mA output and Ethernet connections.

Figure 1. M12 connector

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.

Figure 2. Connecting refractometer cable to refractometer

The PR‑43 refractometer provides both analog (mA) and digital output signals. The following figure shows the wiring when only analog output is used.

Figure 3. Wiring with analog output only
Figure 4. Wiring options with with M12 Ethernet connector. The Compact user interface CI and Multichannel user interface MI use the digital output signal. The following figure shows the wiring options when both analog and digital outputs are used, with M12 Ethernet connector.
Figure 5. Wiring options with RJ45 Ethernet connector. The following figure shows the wiring options when both analog and digital outputs are used, with RJ45 Ethernet connector.
Figure 6. Connections in M12 and RJ45 connectors. The following figure shows the connections that are in the M12 and in the RJ45 connectors.

In split cables the power cable and the mA output cable are marked near the end of the cable.
