Power supply options
The NEMA terminal board is available with an isolated power supply option. This has a 24V isolated
power supply (maximum output load 80mA), U1, fitted. As shown below, U1 completely separates the
terminal 24V and 0V from the pump internal supplies.
This may be used if the sensor requires an isolated supply or has a 4-20mA output which cannot be used
with the ground connected load resistor within the pump.
