Module Description

The module’s front cover is removable. A jumper plug inside the front cover is used to set up the

module as a 32–point or 64–point I/O module.

Serial Ports

The front of the module has two 20–pin connectors that are used to attach the I/O Link cable.

One connector is for the cable to the previous device on the link––either the master or another

slave. The other connector is for the cable to the next slave on the link, if there is one.  See the

RX3i I/O Link Modules User’s Manual, GFK-2358 for more information. Signal levels are

RS422/485 compatible.


An I/O Link Interface Module occupies one module slot in an

RX3i backplane.  It can be installed in any available backplane slot.

The maximum number of I/O Link Interface Modules that can be

installed in the backplane depends on the power that is available

from the power supply.  To determine the exact number of

modules allowed in your system, see the information on power

supplies in chapter 3.

Usually, when there are multiple I/O Link Interface Modules in the

same RX3i system, they are on separate I/O Links.  However, it

is possible to have more than one I/O Link Interface Module in

the system connected to the same link, if that suits the needs of

the application.
