Allen-Bradley 1769-L35CR CompactLogix ControlNet CPU Processor Module

Product Description

The Allen-Bradley 1769-L35CR is a high-performance CompactLogix controller with integrated ControlNet communication. It is designed for applications requiring deterministic, scheduled data exchange and high-speed I/O synchronization.
The controller supports complex control architectures with up to 30 local 1769 I/O modules distributed across three expansion banks. For proper power distribution and signal integrity, the controller must be installed within four slots of the system power supply.

Core Technical Specifications

System Integration and Reliability

The 1769-L35CR is built on the Logix control engine, enabling a common programming environment across multiple Allen-Bradley controller families.
It features battery-backed RAM for data retention during power loss and supports serial programming via 1756-CP3 or 1747-CP3 cables.
Its rugged construction ensures stable operation in industrial environments with demanding thermal, vibration, and humidity conditions.

Installation FAQ

Can multiple 1769-L35CR controllers be installed in the same local chassis?
No. Only one controller can be active in a local 1769 I/O bank. Multiple controllers may communicate over ControlNet, but each must control its own dedicated I/O configuration.
