8.1 PA105-Pre-Amplifier:
The PA105 Pre-Amplifier has an open collector with a max load of 500mA. This is appropriate
for use with sink inputs. This means that the PA105 Pre-Amplifier has a continuous output
equal to the supply voltage. If the supply voltage is 15 volts, then the PA105 will
continuously provide 15 volts – until a pulse comes from the pick-up sensor, closing this
output signal.
8.2 PA106-Pre-Amplifier:
The PA106 Pre-Amplifier has a source output, where the amplitude is equal to the supply
voltage. The maximum current load is 20mA. These are appropriate for source inputs or
pulse inputs. In opposite to the PA105, the out-put signal is always closed – until a signal
from the pick-up sensor comes. The output signal will then have the same amplitude as the
supply voltage. So, if supplied with 12 volts, the amplitude of the output signal will be 12
volts.
