Features:
- Right-Side End Cap Termination for 1769 Compact I/O System Backplane
- Provides Essential Mechanical Protection and Electrical Isolation for I/O Bus Chain
- Operates in Conjunction with the Allen-Bradley CompactLogix Controllers and 1769 I/O Modules
The Allen-Bradley 1769-ECR Controller Module operates as the right end cap in a 1769 Compact I/O system, providing critical bus termination and physical protection for all modules within the rack. It maintains proper signal integrity across the communication backplane by terminating the I/O bus at the rightmost position, ensuring reliable data exchange between the controller and distributed I/O modules. Seamless integration is standard with the 1769-ECR, however proper installation is required to prevent communication errors and electrical interference that could affect system performance. The 1769-ECR has been designed specifically for the Compact I/O platform, incorporating an open-style construction that facilitates convenient mounting and maintenance within industrial enclosures.
The 1769-ECR provides essential termination functions common to the entire rack, and is a critical component of the communication path, directly affecting the proper, normal operation of the overall I/O system. One 1769-ECR end cap is required per rack to complete the I/O bank assembly. The 1769-ECR occupies a dedicated position at the right end of the module chain and is always located at the far right position, the designated end cap slot.
For standard Compact I/O applications, the 1769 System requires the 1769-ECR end cap module installed at the terminal position. In addition to standard bus termination, the 1769-ECR also provides physical protection. The 1769-ECR configuration ensures system integrity using the mechanical and electrical specifications defined in the Compact I/O design.
The 1769-ECR Allen-Bradley Controller Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
