Product Overview

The Allen-Bradley 1769-L18ER-BB1B serves as a high-density, high-performance controller within the CompactLogix 5370 L1 family. This unit integrates a powerful CPU with a comprehensive suite of embedded digital I/O, specifically optimized for small-to-mid-scale automation projects that demand robust networking and a reduced panel footprint. We supply this controller in 100% Brand New original condition, including the factory-shipped 1GB SD card for non-volatile data storage and system recovery.

Technical Specifications

The 1769-L18ER-BB1B architecture combines centralized processing with extensive communication capabilities to support modern smart manufacturing environments.

Engineering Advantages

The 1769-L18ER-BB1B resolves complex cabinet space constraints while providing the high-speed connectivity required for distributed control.

• High-Density Integrated I/O: By embedding 16 digital inputs and 16 digital outputs directly into the chassis, this controller drastically reduces the need for external I/O modules. This consolidation saves DIN rail space and lowers total system hardware costs.

• Resilient Dual-Port Ethernet: The dual Ethernet ports support Device Level Ring (DLR) topologies. This allows the system to withstand a single cable break without losing communication, ensuring continuous production for mission-critical packaging and assembly lines.

• Scalable POINT I/O Architecture: The controller utilizes the 1734 POINT I/O backplane for local expansion. You can add up to 8 expansion modules to the right of the CPU, providing a highly customizable I/O mix within a very narrow physical width.

• Maintenance-Free Data Security: The inbox 1GB SD card provides non-volatile storage for the user program and tag values. This technology eliminates the reliance on internal batteries, reducing long-term maintenance cycles and preventing program loss during extended power outages.

• Unified Engineering Environment: Using Studio 5000 Logix Designer, engineers can program, configure, and manage the 1769-L18ER-BB1B alongside larger ControlLogix systems. This common software environment accelerates development time and simplifies cross-platform integration.

FAQs

• Does this controller require a separate 1769 power supply?

  No. The 1769-L18ER-BB1B features integrated power terminals that accept a direct 24V DC input. It does not utilize the 1769-PA2 or 1769-PB2 bus-style power supplies.

• How does the 1769-L18ER-BB1B differ from the L16 model?

  The L18 model offers expanded performance, specifically supporting up to 8 Ethernet/IP nodes and 8 local POINT I/O expansion modules, compared to the 4 nodes and 6 modules supported by the L16 series.

• Can I use standard 1769 Compact I/O expansion modules?

  The L1 series controllers exclusively support 1734 POINT I/O modules for local expansion. For applications requiring 1769 Compact I/O modules, you must select a 5370 L2 or L3 series controller.

• What is the maximum number of programs this unit can handle?

  The 1769-L18ER-BB1B supports up to 1,000 programs per task, providing ample logic depth for complex machine sequences and multi-stage process control.
