Product Introduction
The Allen-Bradley 1769-ECR is a Right End Cap (ECR) module designed for the CompactLogix controller series. This 1769-ECR functions as a bus terminator, terminating the FlexBus circuitry and signaling the end of a CompactLogix assembly. It is a necessary component to qualify the CompactLogix configuration, ensuring reliable communication between modules.
Installation & Setup Guidance
Installing the Allen-Bradley 1769-ECR requires careful alignment. First, lift the bus lever from its engaged position. Then, align the 1769-ECR with the guide slots on the last CompactLogix module and gently push it until fully seated. Engage the bus lever to connect the 1769-ECR and close the FlexBus. If resistance is felt during lever engagement, inspect alignment. Note that the 1769-ECR must only be installed or removed when power is removed from the system to avoid controller errors.
Compatibility & Integration
The Allen-Bradley 1769-ECR is compatible with all CompactLogix systems that use the 1769 bus architecture. It works with Series A and B modules, and is required to complete the physical and electrical bus. Ensure your system has an available slot at the right end of the module assembly. The 1769-ECR does not require additional configuration; it automatically terminates the bus when installed.

When ordering the Allen-Bradley 1769-ECR, verify that your system is a CompactLogix platform and that the end cap is needed for your specific module count.
