Digital Outputs
The standard Scanner 3100 supports six solid-state digital outputs that are congurable 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 isolated and rated for a maximum of 60 mA at 30 VDC. Maximum frequency is 50 Hz. Wire as
shown in Figure 3.13, page 64 (top diagram). Because the circuit is isolated, it can be used with any other feature on
the Scanner 3100. A two-conductor cable from the Scanner 3100 to the remote location is required.
DIO 5 and DIO 6 are designed for handling signicantly higher currents and can be used to control power to another de-
vice. Wire as shown in Figure 3.13, page 64 (bottom diagram). These terminals are rated for a maximum of 500 mA at
30 VDC. Maximum frequency is 50 Hz.
For reduced power consumption, disable digital outputs using the Scanner 3100 web interface when they are not in use.
