Product Overview

The Allen-Bradley 1769-L16ER-BB1B functions as a high-performance, entry-level controller within the CompactLogix 5370 L1 family. This unit integrates a powerful processor with embedded digital I/O, specifically designed for small-to-mid-sized applications that require a compact footprint without sacrificing network connectivity. We provide this controller in 100% Brand New original condition, complete with the factory-boxed 1GB SD card for non-volatile storage and firmware management.

Technical Specifications

The 1769-L16ER-BB1B combines localized I/O control with dual-port Ethernet capabilities to support Device Level Ring (DLR) topologies.

Engineering Advantages

The 1769-L16ER-BB1B addresses modern manufacturing challenges by consolidating communication, processing, and I/O into a single DIN-rail mounted housing.

• Dual-Port Ethernet for DLR: The two built-in Ethernet ports support Device Level Ring (DLR) topologies. This ensures that the system maintains communication even if a single point in the network ring fails, significantly increasing machine uptime.

• Embedded High-Density I/O: By including 16 digital inputs and 16 digital outputs directly on the base unit, this controller eliminates the cost and space required for additional I/O modules in basic logic applications.

• POINT I/O Expansion Architecture: The L1 series utilizes the 1734 POINT I/O bus for expansion. You can connect up to 6 expansion modules directly to the right side of the controller, allowing for customized digital, analog, or specialty I/O scaling.

• Energy-Efficient 24V DC Operation: The unit operates exclusively on 24V DC power. This simplifies cabinet power distribution and aligns with modern low-voltage safety standards for industrial control panels.

• Non-Volatile Storage Reliability: The included 1GB SD card preserves the user program and tag data during power loss. This eliminates the need for lithium batteries and reduces long-term maintenance requirements.

FAQs

• Does this controller require a separate power supply module?

  The 1769-L16ER-BB1B requires a 24V DC external power source connected to its integrated power terminals. It does not use the traditional 1769-PA2/PB2 bus-style power supplies used by larger L3 controllers.

• Can I use 1769 Compact I/O expansion modules with this L1 controller?

  No. The 1769-L16ER-BB1B uses 1734 POINT I/O modules for local expansion. If your application requires 1769 Compact I/O modules, you should select an L2 or L3 series controller.

• How many Ethernet IP nodes does this model support?

  The 1769-L16ER-BB1B supports up to 4 Ethernet/IP nodes. This makes it ideal for small machines that only need to communicate with a few drives, HMIs, or other PLCs.

• What is the purpose of the USB port on the front panel?

  The USB port provides a high-speed local connection for firmware updates, program uploads, and downloads via Studio 5000 Logix Designer, eliminating the need to configure an IP address for initial commissioning.
