Digital I/O
XL™ Series
Digital I/O 12-1
12.1 Digital I/O Overview
The digital I/O options are very flexible, allowing them to be used for a wide range of
applications. The digital I/O can be uses when a status input or a control output is required.
These two pins can be configured totally independently of each other and can also be used
together for applications using a quadrature input or to simulate a quadrature output.

The XL™ can use the two digital I/O pins to connect to a quadrature shaft encoder such as the
Handar 436A, or to simulate a quadrature shaft encoder. For proper operation with a shaft
encoder that increments clockwise, the phase A signal should be input into pin 1 and the phase B
signal should be input into pin 2.
