3.8 DIGITAL OUTPUTS
Two optocoupled general purpose outputs are available. The meaning of the two outputs
Output 1 and Output 2 can be defined by the user. They are typically used to signal the data
collection result. They are also available to the Host (either serial or Fieldbus) to be driven
independently.
The electrical features of the two outputs are the following:
V
CE
= 30 Vdc max.
I
CE
= 40 mA continuous max.; 130 mA pulsed max.
V
CE saturation
= 1 Vdc max. @ 10 mA
P
D
= 80 mW Max. @ 45 °C ambient temp.
By default, Output 1 is associated with the Partial Read and No Read events, which activates
when the code(s) signaled by the external trigger are not decoded, and Output 2 is
associated with the Complete Read event, which activates when all the selected codes are
correctly decoded.
The output signals are fully programmable being determined by the configured
Activation/Deactivation events, Deactivation Timeout or a combination of the two. Refer to
the Digital I/O folder in the VisiSet™ Help On Line for further details.
3.8.1 Output Connections Using STS400™ Power
CAUTION
Power is available directly to the Output Device, independently from the
Power Supply Switch inside the CBX.
The digital outputs can power and drive small devices meeting the electrical characteristics
above such as electronic switches which can then manage larger power consuming devices
such as signaling lights or other machinery.
