Allen Bradley CompactLogix L1 Controller 1769-L19ER-BB2B

Product Description

The 1769-L19ER-BB2B is a compact, high-performance automation controller designed for small-to-mid-scale industrial systems. Part of the CompactLogix 5370 L1 family, it integrates controller, power supply, and I/O into a single, space-efficient unit. This makes it ideal for machine-level control where DIN-rail space is limited but fast communication and dependable logic execution are required. Expansion is handled via the 1734 POINT I/O platform, allowing scalable growth as system requirements evolve.

Technical Specifications

Application Scenarios

The 1769-L19ER-BB2B is well suited for decentralized control architectures, including conveyor sorting systems, compact packaging machines, and pump or skid-mounted control stations. Its combination of integrated I/O and Ethernet connectivity allows it to function as a localized control hub while coordinating with remote devices.

Frequently Asked Questions

Does this controller require a separate 1769 power supply?
No. The 1769-L19ER-BB2B includes an integrated 24 V DC power supply, unlike CompactLogix L2 and L3 controllers that require external 1769 power modules.

What type of I/O expansion does this model support?
This L1 controller uses the 1734 POINT I/O platform rather than standard 1769 Compact I/O modules.

Can this controller be used for motion control?
No. While it offers fast logic execution, it is intended for discrete and process control and does not support Integrated Motion over EtherNet/IP.
