Figure 21 - IN3/IN4 NPN Input Command using Scanner Power
Input devices can be supplied by either scanner power (VS and GND) or external power
supplies (Vext).
Electrical isolation between the input command logic and the scanner is maintained when
powering the input devices from an external supply voltage (Vext).
The driving logic of the input signals may be powered, for convenience, with the voltage
supply between pins 9 (VS) and 23 (GND) of the 25-pin or 26-pin I/O connector. In this case,
however, the device is no longer electrically isolated.
The voltage available on the 25-pin or 26-pin I/O connector, is physically the same as used
to power the scanner.
The electrical features of these inputs are:
Maximum voltage 30 V
Maximum current 10 mA
Outputs
Three general purpose outputs are available.
