Product Overview
The 1769-ECL a CompactLogix Allen Bradleys 1769 CompactLogix family of controllers. This component is installed after the leftmost module of the chassis to terminate the bus voltage, signaling the last module in the CompactLogix chassis.
The 1769-ECL function is comparable to a terminating resistor. It is a passive device that does not require a power supply or communication cable. The component consumes the excess voltage present in the communication bus. Similarly, the 1769-ECL establishes Processor communication and allows the controller to identify the end of the chassis by terminating the communication bus. Without the 1769-ECL, communication to the chassis will not be possible.
The component is sensitive to electrostatic discharge as it contains electronic components. Before installing, touch a grounded object to discharge static potential, wear an appropriate wrist strap, do not touch conductors and electronic components, store in a static safe location and work on a static safe station.
When installing, locate the last module of the chassis and slide the component from the top using the slot guide from the adjacent module. Push down until proper alignment is reached. Switch the bus lever to establish connection to the bus and terminate the excess voltages.
The component does not support hot-swap feature. Do not attempt to install and uninstall the component on a powered or functioning system. Doing so may render the system not operational, switch to an uncontrollable state or completely shut down the process.
The modules dimension is 3.43 Inches wide, 4.6 inches long and depth of 0.59 inches. VIIIVThe 1769-ECL is a CompactLogix component that belongs to the End Caps and terminator accessories. It is used to terminate the communication bus. This module is installed after the leftmost module of the chassis.
