The PBS is an analog signal amplifier which
accepts an analog voltage or current signal and outputs a voltage
signal.
Several preset input ranges are jumper selectable.
PBS is designed to give a Building Automation
System signal output the power (wattage) to control MaxitrolTM gas
valves normally installed.
The top-adjust trimmer potentiometers can be used
to make fine adjustments of gain and offset.
The output gain can be adjusted anywhere from 1
to 20 times the input on the PBS (gain will vary depending on type of
input). The offset of the output can be +/- 0 to 20Vdc.
By using voltage divider applications, the PBS
can also accept a resistance input.
