A voltage divider. Two resistors in series.
Feed 48 into the end. Ground on the other end. Pick off the analog input in
the middle between the two resistors.
I would make the 48 volt facing resistor 10,000 ohms
The ground facing resistor 2700 ohms. 56 volts will deliver 11.906 volts to
the telemetry.
4.7:1 division

Subject: [AFMUG] Voltage Attenuator?
Picking your brains this morning!
I need to monitor a 48V battery bank in order to activate some actions on a
Control by Web X420 device.
The x420 only takes up to 12v in the analog input, how can I linearly attenuate
de 40-50V range in to a 12v range to make this work?
