Frequently asked questions

What is the maximum I/O capacity for an Allen Bradley 1747-L40E SLC 500 processor?

The 1747-L40E is a fixed I/O processor and does not have expansion slots for additional I/O modules. Its I/O is integrated directly into the processor unit. For systems requiring more I/O, a different SLC 500 controller with expansion capabilities would be needed.
