NI ISM-7413 Ethernet Integrated Stepper User Manual

Figure 19.  

Connecting a PNP Type Proximity Sensor to an Input

Note

When the proximity sensor activates, the input closes.

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

Do not connect the output to more than 30 VDC. The current through the 

output terminal must not exceed 100 mA.
