Chapter

Use of Expansion Modules

Overview

Additional I/O points can be added to the 1760-Lxxxxx-EX Pico

models.

To do this, first install the expansion module and connect the inputs

and outputs. See the following sections of this manual:

Inputs

Use the inputs of the expansion modules as contacts in the Pico circuit

diagram as you would use the inputs on the Pico controller. The

expansion inputs are R1 to R12.
