Installation and Wiring
Group your modules to minimize adverse effects from radiated electrical
noise and heat. Consider the following conditions when selecting a
location for the module. Position the 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 wiring away from any high
voltage I/O wiring.
You can install as many modules as your power supply can support.
However, all 1769 I/O modules have power supply distance rating. The
maximum power supply distance rating is 8, which means that a module
may not be located more than 8 modules away from the system power
supply. The illustration below shows how power supply distance is
determined.
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 on page 3-6, or DIN Rail Mounting on
page 3-7. To work with a system that is already mounted, see Replacing a
Single Module within a System on page 3-7.
