ALLEN BRADLEY 1769-ECR Compact I/O

System Termination with the Allen-Bradley 1769-ECR Right End Cap Module

The Allen-Bradley 1769-ECR is an essential part of the CompactLogix system, designed specifically to serve as the right end cap module. Its primary function is to safely terminate the I/O bus, ensuring reliable communication and electrical performance. Compact in design, it's easy to install and perfect for space-limited applications.

Designed for seamless compatibility with Allen-Bradley CompactLogix controllers, the 1769-ECR provides a secure termination point for your module assembly. It helps maintain signal integrity and supports system stability even in complex industrial environments. Its open-style enclosure design allows for flexibility in mounting and setup.

This right end cap module draws only 5 mA at 5.1V DC and does not require any current from a 24V DC source. This makes it an energy-efficient choice that adds negligible load to your system while still performing a critical function in bus architecture.

The module is rated for operation in altitudes up to 2000 meters or 6562 feet, making it suitable for various industrial settings, including high-elevation facilities. Its robust temperature handling ensures consistent performance in environments ranging from 0 to 60°C (32 to 140°F).

Allen-Bradley has built this unit to last, with support for operating vibrations of 5g between 10 and 500 Hz. The unit is stable under mechanical stress and meets industrial standards for shock resistance. It can withstand up to 20g shock when DIN rail mounted and up to 30g when panel mounted.

Even though the module is not designed for removal and insertion under power (RIUP), it still delivers dependable performance when handled under proper installation conditions. This promotes both safety and longevity of your automation setup.

With a power consumption of 33.6 Watts and power dissipation of 7.5 Watts, the 1769-ECR remains thermally stable during normal operations. These values reflect the efficiency of the module in managing energy while performing its termination role.

The 1769-ECR is available in both Series A and B versions, giving users flexibility when building or upgrading their CompactLogix systems. Both versions maintain compatibility and offer similar reliability in the field.

This module comes with shipping dimensions of 8x8x5 inches and a lightweight build of approximately 130 grams (or 0.286 lbs), which reduces shipping costs and simplifies handling. Despite its compact form factor, it provides heavy-duty functionality for industrial use.

As part of the Rockwell Automation family, this Allen-Bradley module guarantees high-quality performance and durability. It is backed by the company’s reputation for delivering dependable automation solutions.

The 1769-ECR features no external enclosure rating, as it is meant for installation in a protected control cabinet or industrial panel. This aligns with its open-style classification, which is common for end cap components.

This component also complies with IEC and North American temperature codes T4 and T3C, respectively, ensuring it meets international standards for thermal classification. This makes it a globally accepted part for industrial control panels.

By maintaining proper bus termination, the 1769-ECR contributes to noise-free and interference-resistant signal transmission. This is particularly important in large or complex automation systems with multiple interconnected modules.

Whether you're setting up a new CompactLogix configuration or extending an existing one, the 1769-ECR is an indispensable part of your I/O system. Its simple, rugged design makes it a “set-it-and-forget-it” solution in your control cabinet.

With the right end cap in place, you help safeguard your communication bus from open ends and signal reflection. This is crucial for data integrity and minimizes risks of downtime or signal loss in your control architecture.

Since it supports CompactLogix modularity, it fits neatly at the end of your module lineup and locks into place securely. This provides peace of mind that your setup is properly closed and protected.

System designers and engineers prefer the 1769-ECR not just for its function, but also for its ease of installation and minimal maintenance. It adds reliability without complicating your overall setup.

When integrated into your Allen-Bradley architecture, the module helps complete the system in a professional, standards-compliant way. It reflects the high-performance engineering that users expect from Rockwell Automation products.

Because of its low power draw and passive role, the 1769-ECR rarely needs replacement or repair, adding to its cost-effectiveness over the life of the system. It's a small but critical component for long-term operational integrity.

In summary, the Allen-Bradley 1769-ECR is a smart investment for any CompactLogix user. It’s designed to close off your module chain securely, enabling efficient system performance, durability, and safety.

If you're looking for reliable bus termination without adding unnecessary complexity or power drain, the 1769-ECR delivers just that. Compact, efficient, and built to endure tough conditions, it stands as a trusted solution in industrial automation.
