Field Voltage Feedback Function
The board supports seven selectable voltage scaling settings.
It monitors the bridge negative terminal and shunt positive terminal.
Scaled signals enter a differential amplifier circuit.
The amplifier controls the voltage-controlled oscillator.
Stable voltage feedback improves excitation accuracy.
Field Current Feedback Function
The module measures field current through a DC shunt.
The shunt creates a low-level voltage signal.
Maximum input signal reaches 500 mV.
The amplifier converts the signal into a -5V to +5V output.
The design supports stable current monitoring under load changes.
