When the proximity sensor activates, the input closes.
Note
When a device is configured to accept streaming commands through the NI Stepper
Configuration Utility, the EN input is reconfigured to accept an input from a home switch.

Connecting the Digital Output

The NI ISM-7413 has a digital output labeled OUT. You can use this output to automatically
control a motor brake or signal fault conditions. You can also use it to drive LEDs, relays, and
the inputs of other electronic devices like PLCs. The positive collector (OUT+) and negative
emitter (OUT-) terminals of the output transistor are available at the connector. This allows you
to configure the output for current sourcing or sinking.
Diagrams of each type of connection follow.
Caution
output terminal must not exceed 100 mA.
