Allen-Bradley 1768-L45 CompactLogix Controller 3MB Memory

Product Overview

The 1768-L45 is a CompactLogix controller from Allen-Bradley. It offers a 3MB integrated memory. This module supports up to 30 I/O modules across 3 banks. It has one RS232 fully isolated communication port. The controller is designed for medium-sized automation tasks. It can expand with up to four 1768 modules. An optional CompactFlash adds non-volatile memory. The RS232 port supports DF1 and DH485 protocols at 38.4 Kbps. Use the 1747-CP3 or 1756-CP3 cable to connect.

Application Scenarios

This controller suits manufacturing lines and packaging systems. It works well for material handling and motion control. The 1768-L45 can manage I/O, network, and motion demands. It supports Kinetix drives via SERCOS interface modules. It is ideal for medium-sized automated production environments.
