Get now: Allen-Bradley 1769-L16ER-BB1B CompactLogix 5370 L1 Processor
Atlantechdrives provides you the 1769-L16ER-BB1B, an entry-level packaged controller belonging to the CompactLogix 5370 L1 family. This controller is a modern, high-efficiency solution for small-scale machines, integrating a Logix CPU, a 24V DC power supply, and a dedicated bank of digital I/O into a single, compact DIN-rail mounted unit.
- User Memory: 384 KB
- Embedded I/O: 16 DC Inputs / 16 DC Outputs
- Ethernet: Dual EtherNet/IP ports (supports DLR)
- Expansion: Supports up to 6 1734 POINT I/O modules
- Axes of Motion: Supports up to 2 axes of Integrated Motion on EtherNet/IP
Technical Superiority: Modern Control in a Compact Footprint
Purchase now the 1769-L16ER-BB1B to upgrade your control system to the latest Logix standards. This processor is part of the 5370 generation, which replaces the legacy 1769-L2x series. It features dual Ethernet ports that support Device Level Ring (DLR) topologies, allowing for a resilient network where a single cable break does not stop communication. Despite its small size, the L16ER supports Integrated Motion on EtherNet/IP for up to 2 axes, making it a powerful choice for small packaging machines or conveyor systems requiring basic servo coordination. The embedded 16 digital inputs and 16 digital outputs are 24V DC rated, providing a complete «out-of-the-box» control solution. By choosing the 1769-L16ER-BB1B, you benefit from a controller that utilizes the same programming environment (Studio 5000) as the much larger ControlLogix systems, ensuring code portability and future scalability.
Installation Advice: Managing POINT I/O Expansion
A unique feature of the 1769-L16ER-BB1B is that it utilizes the 1734 POINT I/O platform for expansion rather than the standard 1769 bus. When installing expansion modules, ensure that the total current draw does not exceed the capacity of the embedded power supply. If you require more than 6 modules or high-current analog cards, you must install a 1734-EP24DC expansion power unit. Always ground the DIN rail to the panel’s common ground point to prevent communication glitches between the CPU and the POINT I/O bus. For Ethernet connectivity, the dual ports act as an internal switch, which simplifies wiring but requires careful IP address management during commissioning.
Maintenance and Lifecycle Protection
The 1769-L16ER-BB1B is a modern controller that does not require a battery for program retention, utilizing internal non-volatile energy storage instead. Maintenance is primarily focused on firmware management. We recommend keeping the controller within its 0-60°C operating temperature and periodically checking the «OK» and «NS/MS» status LEDs. Sourcing your 1769-L16ER-BB1B from Atlantechdrives ensures you get a unit with healthy I/O points and verified communication ports, ready for long-term industrial service.
FAQs
Q: Does the 1769-L16ER-BB1B require a separate power supply?
A: No, it has an integrated 24V DC power supply; it simply needs 24V DC input power to run the CPU and I/O.
Q: Can it be programmed with RSLogix 500?
A: No, all CompactLogix 5370 controllers require Studio 5000 Logix Designer software.
