9/Series Adapter Modules for
1771 and 1746 I/O Devices
This section discusses using I/O adapter modules for the 9/Series I/O ring.
These adapter modules allow you to use Allen-Bradley’s 1746 I/O or 1771
I/O modules in the 9/Series I/O ring. This is accomplished by placing an
adapter module in the I/O chassis that will interface to the 9/Series fiber
optic I/O ring. These modules always reside in the first slot of the I/O
chassis and replace the logic controller CPU or ASB adapter module that
would typically reside in the first slot.

Use the 1771 I/O Ring Adapter Module to interface an Allen-Bradley 1771
series B I/O chassis with the control. The 1771 I/O ring adapter module
provides the system installer with the option of using a 1771 series B I/O
chassis for discrete inputs and discrete outputs to the control (only discrete
I/O cards are compatible with the 1771 adapter module). Use page 10B-10
to calculate how many ASRN chips are required for each I/O chassis.
The adapter module must be placed in the first slot of the 1771 series B I/O
chassis. The 1771 series B I/O chassis is then interfaced with the
fiber-optic I/O ring of the control using the fiber optic connectors on the
adapter module. Refer to the Allen-Bradley 1771 I/O Ring Adapter
Module Product Data Sheet, publication 8500-4.5.1, for additional
information on this module. No more than 16 1771 I/O adapter modules
can exist on the 9/Series I/O ring.
