CompactLogix Ethernet Processor 1769-L35E Allen Bradley

Product Description

The 1769-L35E is a high-performance CompactLogix controller designed for small to medium-scale industrial automation applications. It offers integrated EtherNet/IP communication, modular I/O expansion, and versatile connectivity via an RS-232 port. Ideal for complex process control, motion systems, and data-intensive applications, the L35E provides robust memory and I/O capacity while maintaining a compact footprint.

Technical Specifications

Key Features

• High Memory Capacity: 1.5 MB allows for more extensive logic, tagging, and instruction sets compared to the L32E (0.75 MB).

• Dual Connectivity: Built-in EtherNet/IP and RS-232 for modern and legacy system integration.

• Modular I/O Support: Connect up to 30 1769 I/O modules directly to the CPU without a separate chassis.

• Battery Backup: 1747-BA lithium battery preserves program and tag data during power outages.

Application Scenarios

• Automated assembly lines

• Packaging machinery

• Water treatment and chemical processing systems

• Complex PID control for temperature, pressure, or flow regulation

Frequently Asked Questions

Q: How does the L35E compare to the L32E?
A: The L35E offers triple the memory (1.5 MB vs 0.75 MB), supporting more extensive programs and tags. Both have similar EtherNet/IP connectivity, but the L35E is better suited for larger, more complex control systems.

Q: Does it require a battery?
A: Yes, the 1747-BA lithium battery is required to retain memory during power loss.

Q: How many I/O modules can I connect?
A: Up to 30 local 1769 modules across 3 I/O banks, within the 4-slot distance rating from the power supply.
