Digital Outputs
The standard Scanner 3300 supports eight solid-state digital outputs that are configurable as pulse outputs, alarm outputs,
conditional outputs, or programmed outputs using time of day or an output state as the trigger.
DIO 1 through DIO 4 are galvanically isolated and rated for a maximum of 60 mA at 30 VDC with a maximum frequen
-
cy of 500 Hz. DIO 5 and 6 are non-isolated and rated for a maximum of 500 mA at 30 VDC with a maximum frequency
of 500 Hz. Wire as shown in Figure 3.16 . Because DIO 1 to 4 are isolated, they can be used with any other feature on the
Scanner 3300. A two-conductor cable from the Scanner 3300 to the remote location is required for each output.
