Chapter 4: I/Os
You can create an I/O configuration for Vision OPLCs using both Snap-in I/O Modules and
I/O Expansion Modules.
• Snap-in I/O Modules
This provides a Vision OPLC with an on-board I/O configuration. These modules snap
directly onto the back of the controller.
• I/O Expansion Modules
Via an adapter, you can connect a broad variety of I/O modules to a Vision OPLC’s I/O
expansion port.
• Turn off the power before installing I/O modules.
Installing a Snap-in I/O Module
You can install a Snap-in I/O Module both before and after mounting the unit.
Note the protective cap covering the I/O connector on the back of the controller. This cap must
cover the connector whenever a Snap-in I/O Module is not attached to the controller. You must
remove this cap before installing a module.
1. Pry the cap, shown in Figure 6, page 14, off using the blade of a screwdriver.
2. Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O
Module as shown below.
3. Apply even pressure on all 4 corners until you hear a distinct ‘click’. The module is
now installed. Check that all sides and corners are correctly aligned.
