1785-L40C15

Overview

The 1785-L40C15 is an Allen-Bradley PLC-5 controller designed for efficient automation control. It supports a maximum of 2048 I/O points (input or output) and offers a range of communication options, including Data Highway Plus (DH+), Remote I/O (RIO), and ControlNet. It provides a high level of flexibility in memory expansion and supports redundancy for increased reliability.
