IMPORTANT: In 4, the “Power and Output Wiring (J1)” section is replaced with the following
section.
Power and Output Wiring (J1)
In most applications the power is supplied from the controller that is receiving the 4-20mA output.
In these applications only three wires are required in case of single sensor unit and only four wires
are required in case of dual sensor unit since common is shared.
If the 4-20mA output is going to another device other than the one that is powering it, or the
transmitter has its own local power supply, another connection from GND must be extracted for
the 4-20mA loop to function.
