Rockwell Automation Publication 1715-UM001J-EN-P - December 2020 65
Chapter 2 Installation Instructions
that only I/O modules appropriate to the termination assembly type can be
installed.
Each redundant I/O subsystem supports a maximum of 24 I/O module slots,
which can be configured with 24 simplex I/O termination assemblies, 12
duplex I/O termination assemblies, or any combination in between.
Once the base units and termination assemblies have been installed, the
insertion and removal of modules does not disturb other electrical
connections.
Mount Termination Assemblies
Termination assemblies connect to I/O base units. A combination of duplex
and simplex Termination Assemblies may be mounted. A duplex Termination
Assembly may be mounted across two I/O base units. The combination that is
used depends on the specific configuration requirements of the system.
To connect termination assemblies to I/O base units, follow these steps.
1. Insert the termination assembly (TA) retaining clip on the back of the
termination assembly into the slot on the I/O base unit.
2. Press in and slide the assembly upward as far as it goes until it locks in
place.
