Functional Description
Amplifier Amp 3 increases the voltage of the reference source
amplification factor can be altered by external wiring. With direct setting of the window,
the input voltage appears on amplifier Amp 1 (
comparator K2 (
With indirect setting of the window, the input voltage appears on inputs
the center voltage is connected to amplifier A1 (
The voltage applied to the input (
the output voltage of amplifier Amp 1 and added. The comparators switch with
hysteresis. The logic gates have open-collector outputs.
If the inhibit input A or B is connected to ground, output A or B will always be high.
