Chapter 3 Input Module Features
Short Circuit Protection
Short Circuit Protection helps prevent damage to a test output on a 5069-IB8S
or 5069-IB8SK module that can result when more current is present at the
output than it can handle.
The diagnostic is supported on all module outputs, that is, the Test Output
points and the Test Output/Muting Output points.
Table 18 describes what happens when a short circuit condition is detected.
To correct the issue, remove the short.
Table 19 describes what happens when the short circuit condition is
corrected.
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
