This Allen Bradley CompactLogix packaged controller, part number 1769-L23E-QBFC1B, belongs to the 1769 CompactLogix product family. This controller has embedded functionalities that allow it to control automation requirements right out of the box. CompactLogix packaged controllers include an embedded power supply, along with sixteen (16) twenty-four (24) volts direct current (DC) sinking input channels, as well as sixteen (16) twenty-four (24) volts direct current (DC) sourcing output channels and four (4) single ended or differential analog input channels, along with two (2) single ended analog output channels and four (4) high-speed counter channels. Furthermore, this module also has one (1) RS-232 communication port for point-to-point connections and one (1) Ethernet communication port for connecting to an Ethernet network for simultaneous and multiple connectivity. This module's integrated memory is five hundred and twelve (512) kilobytes of volatile memory. Additionally, this controller includes an end cap for terminating the local Input or Output bus. This controller includes light emitting diode (LED) status indicators for each output channel, as well as indicators for operating mode and battery status. Since this module has a compact design, operators can install it in a small enclosure space, requiring only 50 millimeters, or 1.97 inches, of clearance. This spacing requirement allows for adequate airflow for the controller's natural ventilation. Following this requirement helps to ensure that the controller operates continuously and without interruption. Moreover, the Ethernet communication port on this Allen Bradley module allows it to connect to an Ethernet network by using standard RJ45 connectors installed at both ends of a Cat5 or Cat6 communication cable.
