Product Overview
The 1785-LT2 is a Classic PLC-5/25 processor module in the Allen-Bradley PLC-5 family. It executes control logic, interfaces with remote and local I/O racks, and connects via Data Highway Plus and Remote I/O channels. Designed for discrete logic and analog I/O in mid-to-large industrial systems, it is applied in manufacturing lines, batch processing, and infrastructure controls. 1785-LT2 provides expandable memory and supports redundancy for high-availability systems.
