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