Short Circuit Protection
Short Circuit Protection helps prevent damage to the output that can result
when more current is present at the output than it can handle.
Short Circuit Protection with Standard Output Modules
describes what happens when a short circuit
condition is detected
on
a Compact 5000 I/O standard output module.
To correct the issue, you must remove the short circuit condition.
describes what happens when the short circuit
condition is corrected
on a Compact 5000 I/O standard output module.
For more information on the maximum current that you can apply to an
output, see the Compact 5000 I/O Modules and EtherNet/IP Adapters
