1769-L19ER-BB1B is a CompactLogix 5370 L1 controller. Rockwell Automation identifies 1769-L19ER-BB1B as a CompactLogix 5370 L1 controller with 1 MB user memory, 24 VDC operation, 16 sinking digital inputs, 16 sourcing digital outputs, two EtherNet/IP ports with DLR support, up to eight EtherNet/IP nodes and up to eight local POINT I/O expansion modules. The product listing states that a 1 GB SD card is included.
Before replacement, back up the project and match the complete order code, hardware series, supply, field wiring, network topology, expansion modules and firmware. Rockwell Automation currently lists 1769-L19ER-BB1B as Active. Confirm current orderability, exact series/revision and system compatibility at quotation.
The 1769-L19ER-BB1B may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
1769-L19ER-BB1B documentation and reference links.
Important Notice: Confirm the complete catalog identity, hardware revision, receiving-system configuration and required document revision before replacement.
The controller has 16 sinking 24 VDC inputs and 16 sourcing 24 VDC outputs. Verify field voltage, polarity, commons, output load and terminal wiring against the exact controller and installation instructions.
Two embedded EtherNet/IP ports support DLR network arrangements. Keep the controller IP configuration, ring supervisor settings, node count and project communications consistent with the approved network design.
Rockwell specifies support for up to eight local POINT I/O expansion modules. Confirm the expansion interface, module sequence, power budget and controller firmware in the project before adding or replacing hardware.
