PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1769-ECR is a CompactLogix Right End Cap bus terminator. It terminates the 1769 Compact I/O communication backplane on the right side. This accessory attaches directly to the rightmost module of the rack. It functions as an open-style component without a separate enclosure.
The unit draws 5 mA at 5.1V DC and 0 mA at 24V DC. It operates across a temperature range of 0 to 60 degrees Celsius. Supported relative humidity spans 5 to 95 percent in non-condensing environments. The terminator supports DIN rail mounting or direct panel mounting configurations.
