P/S
More than one external power supply can be used provided all the power supply commons are connected.
A Series 217, 0.032A, fast-acting fuse is recommended for 4–20mA current loops.
If the power supply common of an external power supply is not connected to 0VDC on the
module, then the output of the external transmitter must be isolated. To avoid "ground loop"
errors, recommended 4–20mA transmitter types are:
2 or 3 wire: Isolation between input signal and power supply.
