Overview
Product FunctionAllen-Bradley 1769-ECL CompactLogix Left-End Cap
The Allen-Bradley 1769-ECL is a left-end cap for the CompactLogix 1769 Compact I/O system. It closes the left end of the communication bus and provides the correct termination for the I/O assembly. Unlike a right-end cap, this model has a specific left-side position. In addition, it draws only 5 mA at 5.1 VDC.
Product Function
The 1769-ECL closes the left end of the 1769 Compact I/O communication bus. It serves as an end termination component rather than an active I/O module. Therefore, it does not provide input or output channels.
Furthermore, its position distinguishes it from a right-end cap. When selecting a replacement, check the existing bus layout to ensure that the component matches the required termination side.

Installation and Configuration
Install the 1769-ECL at the left end of the 1769 Compact I/O communication bus. Meanwhile, make sure the assembly uses the correct end-cap type for its layout. A left-end cap and a right-end cap serve different positions, so they should not be treated as interchangeable parts.
Frequently Asked Questions
Q: What does the Allen-Bradley 1769-ECL do?
A: The 1769-ECL closes the left end of the 1769 Compact I/O communication bus. It provides bus termination and does not function as an I/O channel module.
Q: Can the 1769-ECL replace a right-end cap?
A: No. The 1769-ECL is designed for the left end of the bus. Therefore, check the required installation position before ordering a replacement.
Q: What is the current draw of the 1769-ECL?
A: It draws 5 mA at 5.1 VDC and 0 mA at 24 VDC. These values describe its current requirements at the two specified supply voltages.

Installation and Configuration
The 1769-ECL is intended for the left end of the 1769 Compact I/O communication bus. In addition, its termination function distinguishes it from other end-cap configurations. When replacing an existing component, check the installation position and confirm that the replacement matches the required left-end configuration.
Frequently Asked Questions
Q: What is the function of the Allen-Bradley 1769-ECL?
A: The 1769-ECL terminates the left end of a 1769 Compact I/O communication bus. It provides the designated end connection for the I/O assembly.
Q: Is the 1769-ECL a left-end or right-end cap?
A: It is a left-end cap. It should not be confused with a right-end termination component.
Q: What is the current consumption of the 1769-ECL?
A: Its current draw is 5 mA at 5.1 VDC and 0 mA at 24 VDC.
