Specification

The 1769-ECR ALLEN-BRADLEY is a critical component for any CompactLogix system, serving as the right-end termination cap that physically and electrically closes the I/O bus. Without this module, the system cannot operate reliably, as it prevents data reflection and ensures stable communication across the backplane. Designed for use with all 1769-series I/O modules and controllers, the 1769-ECR provides a secure mechanical latch and a compact footprint (only 14 mm wide) to maximize panel space. Its robust construction meets UL, CSA, and CE standards, making it suitable for global industrial automation projects. Below are the detailed specifications based on standard Allen-Bradley documentation.
