Allen-Bradley 1768-L45 CompactLogix Controller 3MB Memory

Product Overview

The Allen-Bradley 1768-L45 is a CompactLogix controller. It offers Logix platform capability for medium-sized applications. This module has an integrated 3MB memory. It includes one fully isolated RS232 communication port. The port supports DF1 Full and Half Duplex protocols. It also supports DH485 protocol. The controller can use optional non-volatile memory. This uses a CompactFlash 1784-CF128. It supports up to two communication modules. For Ethernet, use 1768-ENBT or 1768-EWEB. The controller supports up to 30 I/O modules in three banks. It requires a backplane current of 2.0 Amps at 24 Volts.

Application Scenarios

This controller fits medium automation tasks. It handles motion, I/O, and network demands. Use it in manufacturing lines, packaging systems, and material handling. The 1768-L45 works well with 1768 and 1769 modules. It supports up to four 1768 modules and thirty 1769 I/O modules. Suitable for applications needing Logix capabilities. It integrates motion control with Kinetix drives via SERCOS interface modules. It also supports Ethernet communication for data integration.
