Information About 1769-ECR

The 1769-ECR is part of the Allen-Bradley CompactLogix product line, designed to be installed at the right end of a module assembly. It draws 5 mA at 5.1V DC and provides no current draw at 24V DC. This end cap ensures proper termination of the FlexBus circuitry, making it a required component for valid CompactLogix configurations. The module features an open-style enclosure and weighs approximately 130 g (0.286 lb), with a shipping weight of 2 lbs. It operates at altitudes up to 2000 m (6562 ft), within a temperature range of 0–60 °C, and tolerates relative humidity up to 95% non-condensing. Shock and vibration ratings include 20g when DIN rail mounted and 30g when panel mounted, with vibration resistance up to 5 g at 10–500 Hz. For safety, the 1769-ECR must be installed or removed only when system power is off to avoid controller faults or stoppage.

Key Features:

  • Function: Right End Cap module that terminates the FlexBus and completes CompactLogix assemblies.
  • Power draw: Requires only 5 mA at 5.1V DC, with no current draw at 24V DC.
  • Installation: Mounted at the rightmost position of the chassis; engages with a bus lever to ensure secure connection.
  • Environmental ratings: Operates between 0–60 °C (32–140 °F), with storage capacity from -40 to 85 °C (-40 to 185 °F).
  • Humidity tolerance: Supports 5–95% relative humidity, non-condensing, for stable performance in various environments.
  • Shock resistance: Rated 20g when DIN-rail mounted and 30g when directly enclosure-mounted.
  • Vibration tolerance: Withstands up to 5 g vibration at 10–500 Hz, ensuring durability in industrial settings.
  • Weight & dimensions: Weighs 130 g (0.286 lb), shipping weight of 2 lbs with dimensions of 8 × 8 × 5 in for transport.

The 1769-ECR delivers the reliability and precision required for secure termination and safe operation of CompactLogix controller systems.

Frequently Asked Questions about 1769-ECR
Question: What is the primary function of the 1769-ECR module?
Date Update:23/05/2025
Answer:

The 1769-ECR serves as a right-end cap for CompactLogix and MicroLogix 1500 systems. It terminates the communication bus, ensuring proper signal integrity across the I/O modules. Without this module, the system may experience communication errors or instability. Its installation is crucial for the reliable operation of the controller assembly.

Question: Does the 1769-ECR require any specific mounting considerations?
Date Update:23/05/2025
Answer:

The 1769-ECR can be mounted on a DIN rail or directly onto a panel. When mounted on a DIN rail, it can withstand shocks up to 20 g; panel mounting allows for shocks up to 30 g. Ensure that the mounting method chosen aligns with the environmental conditions of the installation site. Proper mounting ensures the module's durability and performance.

Question: Is the 1769-ECR module required in a CompactLogix system?
Date Update:23/05/2025
Answer:

Yes, the 1769-ECR is required for all CompactLogix and MicroLogix 1500 systems that use 1769 I/O modules. It terminates the FlexBus communication line at the end of the I/O module chain and is essential to ensure data integrity and proper system operation. Without the ECR, the system may experience communication errors or fail to recognize the final module. Therefore, it must be installed on the rightmost side of the last I/O module.

Question: What is the difference between 1769 and 5069 series modules?
Date Update:23/05/2025
Answer:

The 1769 series belongs to the CompactLogix platform, designed for mid-range automation tasks and widely used in legacy or transitional systems. In contrast, the 5069 series is part of the CompactLogix 5380 and Compact GuardLogix 5380 platforms, offering faster processing, higher I/O density, improved diagnostics, and enhanced security features. 5069 modules use a newer backplane protocol and are not backward-compatible with 1769. The shift to 5069 reflects Rockwell’s focus on modernizing control systems with more performance and scalability.

Question: What is the physical size and weight of the 1769-ECR module?
Date Update:23/05/2025
Answer:

The module measures approximately 118 mm (4.65 inches) in height, 32 mm (1.26 inches) in width, and 85 mm (3.35 inches) in depth. It weighs around 130 grams (0.286 pounds). Its compact size allows for easy integration into control panels with limited space. The lightweight design simplifies handling during installation.

Question: Is the 1769-ECR module still in production?
Date Update:23/05/2025
Answer:

Yes, according to Rockwell Automation, the 1769-ECR module is currently active and available for purchase. It remains a supported component within the CompactLogix product line. For the most up-to-date information, refer to the official Rockwell Automation product page. Regularly checking the product status ensures compatibility with future system expansions.
