53Handler Interface
8.3 ElectricalCharacteristics
8.3.1 InputSignal:
Each input signal is connected to the LED (cathode side) of the photo-coupler. The LED
(anode side) is connected to the pull-up power supply voltage.
8.3.2 OutputSignal:
Each output signal is outputted via an open collector by using a photo-coupler. The
voltage of each output is obtained by connecting pull-up resistors, inside or outside of the
AT281x.
8.3.3 Powersupply
The power supply for the judgment output signal pull-up and that for the operation
output signal pull-up and input signal drive can be set separately. You can select from
+3.3V to +35V external power supply.
