Isolating a Digital Input with an Optocoupler

When driving current through the LED, the Digital Input will 

report TRUE.  The amount of current required will depend 

on the optocoupler used.  Design to sink at least 280µA to 

cause the digital input to report TRUE, and less than 190µA 

to report FALSE.

Detecting an external Voltage with an NPN Transistor

This circuit can be used to measure if a battery is connected, or if 12V 

(for example) is on a wire.
By designing to have Collector-Emitter current > 280µA, the digital 

input will report TRUE. 

Using a Capacitive or Inductive Proximity Switch

Capacitive proximity switches can detect the presence of nearby 

non-metallic objects, whereas inductive proximity switches 

can detect only the presence of metallic objects.  To properly 

interface one of these proximity switches to the digital inputs, a 

3-wire proximity switch is required, as well as an external power 

supply.
We have checked the following switch from Automation Direct 

to verify that it works with the Digital Inputs.  Similar capacitive 

or inductive proximity switches from other manufacturers should 

work just as well.
