Output Signals

The digital I/O connector handles output signals 0001 to 0008. Refer to Table 3-3 for
output specifications. The locations of the signals on the connector are shown in Table 3-4.
The SIO provides separate + and – connections for each channel (no internal common
connections.) This allows you the choice to wire for current-sourcing or current-sinking
mode as required.
Each output channel (circuit) should be connected to only one output device. Each output
circuit is short-circuit protected.

CAUTION: The above specifications for the digital inputs and outputs on
the SIO module are different than the specifications for a DIO module.
!
Specifically, the SIO output current is limited to 100 mA per channel,
whereas the DIO output is rated at 400 mA.
