4.2 Wiring
If the power ground terminal and the negative 4–20mA terminal in the controller are internally connected
(non-isolated 4–20mA input), it is unnecessary to connect the 4–20mA negative wire (green) to the 4–20mA
negative terminal in the controller. If a separate DC power supply other than that from the controller is used,
make sure that the output from the power supply is rated for 22–26 VDC @ 65mA.

NOTE
*
The negative 24V power terminal (power ground) and the negative 4–20mA ter-
minal on the LSP-X01 Series probe are internally connected.
