2.3.6 Inputs
ENC is the encoder input and detects the conveyor speed.
EXT_TRIG is the presence sensor that, when active, tells the scanner that a pack is entering
the reading area.
All inputs are optocoupled and driven by a constant current generator; the command signal is
filtered through an anti-disturbance circuit which generates a configurable delay of about 5
ms or 500
µ
s.
The electrical features of the inputs are:
Maximum voltage 30 V
Maximum current 10 mA
Input NPN
Polarity Insensitive Common Reference
