Universal Input module
•
away from sources of electrical noise such as hard-contact switches,
relays, and AC motor drives
•
away from modules which generate significant radiated heat, such
as the 1769-IA16. Refer to the module’s heat dissipation
specification.
In addition, route shielded, twisted-pair analog input wiring away from
any high voltage I/O wiring.
Power Supply Distance
You can install as many modules as your power supply can support.
However, all 1769 I/O modules have a power supply distance rating.
The maximum I/O module rating is 8, which means that a module may
not be located more than 8 modules away from the system power
supply.
System Assembly
The module can be attached to the controller or an adjacent I/O module
before or after mounting. For mounting instructions, see Panel
Mounting Using the Dimensional Template, or DIN Rail Mounting. To
work with a system that is already mounted, see Replacing a Single
Module within a System.
The following procedure shows you how to assemble the Compact I/O
system.
