YOKOGAWA VY Series - Connection between Integral Type and Remote Transmitter

4.3 Connection Between Integral Type and Remote Transmitter
Table 4.1 shows an example of wiring between the power supply and load resistance. Figure 4.2 shows the
position of each connection terminal.
In the case of communication and input/output code JA, "SUPPLY +,-, D
OUT
+,-" is indicated on the wiring
instruction label. In the case of communication and input/output code JB, "SUPPLY +,-, D
OUT
+,-, A
IN
+,-" is
indicated on the wiring instruction label.
