Allen-Bradley 1769-L16ER-BB1B CompactLogix 5370 L1 Controller

Product Overview

The Allen-Bradley 1769-L16ER-BB1B functions as a high-performance entry-level Programmable Automation Controller (PAC) within the CompactLogix 5370 L1 family. This controller integrates processing, power supply, and local I/O into a single, space-efficient unit. It targets small to medium-scale machine control applications requiring integrated motion over EtherNet/IP and high-density onboard digital signals. We supply this unit as 100% brand new and original, ensuring the highest level of firmware compatibility and hardware longevity for your control system.

Technical Specifications

The 1769-L16ER-BB1B utilizes a sophisticated multi-tasking architecture to execute complex logic:

• Embedded I/O: 16 Digital DC Inputs and 16 Digital DC Outputs

• Ethernet Communication: 2 Ports (Supports Linear and Device Level Ring topologies)

• USB Interface: 1 USB Port (Programming and Configuration)

• Controller Tasks: Supports up to 32 Tasks

• Task Capacity: 100 Programs per Task

• Connection Capacity: 256 Controller Connections

• Socket Support: Maximum 32 Sockets

• Local Expansion: Supports up to 6 Bulletin 1734 POINT I/O Modules

• Operating Temperature: -20°C to 60°C (-4°F to 140°F)

• Storage Temperature: -40°C to 85°C (-40°F to 185°F)

• Weight: 1.50 lbs (0.68 kg)

Engineering Advantages

• Integrated I/O Consolidation: The onboard 16-point DC input and 16-point DC output array eliminates the need for separate I/O modules in basic machine designs. This consolidation reduces the physical footprint of the control system and lowers total hardware costs.

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

• Seamless POINT I/O Expansion: The 1769-L16ER-BB1B utilizes the 1734 POINT I/O backplane for local expansion. This allows engineers to add up to 6 specialized modules (analog, safety, or specialty I/O) directly to the right of the controller without increasing cabinet depth.

• Battery-Free Operation: This 5370 series controller employs an internal energy storage module to write data to non-volatile memory during power loss. This eliminates the maintenance requirement for lithium batteries and prevents program loss in long-term storage.

• Broad Environmental Tolerance: With an operating range of -20°C to 60°C, the controller survives in unheated field enclosures and high-temperature manufacturing zones. The ruggedized internal components resist the thermal cycling common in industrial environments.

FAQs

• What software do I need to program the 1769-L16ER-BB1B?

  You must use Studio 5000 Logix Designer software. The specific version depends on the firmware revision of the controller, typically requiring version 20 or higher to access the full feature set of the 5370 L1 family.

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

  No. The L1 series (1769-L1x) specifically uses 1734 POINT I/O for local expansion. If your application requires 1769 Compact I/O modules, you should select an L2 or L3 series CompactLogix controller instead.

• How many axes of motion does this controller support?

  The 1769-L16ER-BB1B supports up to 4 axes of Integrated Motion on EtherNet/IP, though it only allows for 2 "Position Loop" axes. Always check your specific application timing and CPU utilization when configuring motion tasks.

• Does the unit include the power supply?

  Yes. The 1769-L16ER-BB1B features an integrated 24V DC power supply that powers the controller, the embedded I/O, and the local 1734 expansion modules, simplifying your cabinet power distribution.
