This module is required to terminate the communication bus of a 1769 I\/O bank, ensuring signal integrity and proper backplane operation. Without the 1769-ECR, the controller will not be able to communicate with the I\/O modules in the bank, making it an essential piece for system startup and stability.\u003c\/p\u003e\n\u003ch2 id=\"technical-configuration\"\u003eTechnical Configuration\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Rockwell Automation \/ Allen-Bradley\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e CompactLogix \/ 1769 Compact I\/O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e \u003cspan style=\"color: #2e86c1;\"\u003e\u003cstrong\u003e1769-ECR\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Type:\u003c\/strong\u003e Right End Cap \/ Terminator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Draw:\u003c\/strong\u003e 5 mA at 5V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackplane Current:\u003c\/strong\u003e 1.4 Amps at 24V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Type:\u003c\/strong\u003e Open-style Rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 id=\"technical-specifications\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #cccccc; margin-bottom: 20px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc; background-color: #f9f9f9;\"\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc;\"\u003e\u003cstrong\u003e0.13 kg (approx.)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc; background-color: #f9f9f9;\"\u003e\u003cstrong\u003eOperating Temp\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc;\"\u003e0-60°C (32-140°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc; background-color: #f9f9f9;\"\u003e\u003cstrong\u003ePower Dissipation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc;\"\u003e7.5W\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc; background-color: #f9f9f9;\"\u003e\u003cstrong\u003eVibration Resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc;\"\u003e5 g (10-500 Hz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid #cccccc; background-color: #f9f9f9;\"\u003e\u003cstrong\u003eTemp Codes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd colspan=\"3\" style=\"padding: 10px; border: 1px solid #cccccc;\"\u003eNorth American T3C; IEC T4; Altitude Limit 2000m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2 id=\"installation-guide\"\u003eInstallation \u0026amp; System Roles\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e1.

Power Considerations:\u003c\/strong\u003e While the 1769-ECR has a minimal bus current draw of 5 mA at 5V DC, it is rated for a total power consumption of 33.6W. Ensure your 1769 power supply has adequate headroom to support the entire bank including this termination module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.

Attempting to remove or install the end cap while the system is powered may result in a major controller fault or damage to the I\/O backplane connectors.\u003c\/p\u003e\n\u003ch2 id=\"engineering-advantages\"\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eThe 1769-ECR provides a mechanical and electrical finish to the 1769 platform. Its robust vibration resistance (5 g) ensures it maintains bus contact even in high-vibration machinery environments. By meeting T4 IEC temperature codes, it is suitable for a wide range of global industrial applications, ensuring the communication signals within the CompactLogix backplane remain noise-free and properly balanced.\u003c\/p\u003e\n\u003ch2 id=\"technical-faqs\"\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: Can I use a left end cap instead of a 1769-ECR?\u003c\/strong\u003e\u003cbr\u003eA1: No, the 1769-ECR is specifically designed for the right side of the bank. Left-side termination is typically handled by the controller or a power supply module depending on the rack configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Why is my controller showing an I\/O fault after assembly?\u003c\/strong\u003e\u003cbr\u003eA2: A common cause is a missing or improperly seated 1769-ECR. Ensure the end cap is firmly snapped into the last module to complete the bus circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Does this module require any software configuration?\u003c\/strong\u003e\u003cbr\u003eA3: No, the 1769-ECR is a passive electrical terminator and does not require a software identity or configuration in Studio 5000.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":51050792779908,"sku":"1769-ECR","price":201.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1769-ECR_2.jpg?v=1776092370","url":"https:\/\/www.etowonauto.com\/az\/products\/1769-ecr-allen-bradley-compact-i-o-right-bus-terminator","provider":"Etowon Auto","version":"1.0","type":"link"}
