All Field Control I/O modules require field-side power for their I/O devices. Power supply
connections can easily be “daisy-chained” between modules with similar power requirements.
There is a 10 Amp maximum limit on any one screw. Alternatively, separate supplies can be used
on any combination of modules to provide isolation as needed.
The location of the power connection on an I/O module depends on the module type. For
information on power connection to a specific type of module, refer to its individual module
datasheet.
Power Wiring for Hot Insertion/Removal
For Hot Insertion/Removal of modules, power must be switched off to the module being inserted or
removed. A means of removing power to the module should be provided during installation.
Noise Immunity
Good wiring practices are the foundation for reliable and predictable system operation.
The electrical environmental standards listed in chapter 1 should be used as benchmarks. Uncontrolled
combinational effects in a real installation, higher levels of noise, or sources of noise with different
properties from those in the Standard can still cause problems. Therefore, it is important to follow
prudent wiring and suppression practices in the installation.
Wiring external to equipment and in cable trays should be separated following accepted practices.
