The electromagnetic flowmeter converter can be divided into integrated converter and separated
converter, and the wiring diagram is shown in Figure 5 and Figure 6.
When wiring, please note:
a) RS485 communication cable needs to use two-core twisted pair shielded wire;
b) The same cable shall not be used for the power line and 4mA~20mA DC signal line. Two cables
shall be connected separately.

Integrated wiring

7.1
When wiring, select the corresponding power terminal to connect to the power line according to the
product specifications, and then connect to the signal line according to the required output signal. See
Table 2 for the specific meaning of the integrated electromagnetic flowmeter wiring terminals.
