Product Overview
The 1785-L40C is an Allen-Bradley PLC-5 series ControlNet processor. It functions as a microprocessor control module that resides in the left-most slot of a 1771 I/O chassis and manages discrete and analog I/O via ControlNet network communication. The 1785-L40C supports peer-to-peer or scheduled I/O updates in industrial automation systems, typically applied in process control, material handling, or machine automation where ControlNet integration within a PLC-5 legacy system is required. This description refers specifically to part number 1785-L40C.
