The 1756-L84EK controller is an Allen-Bradley ControlLogix controller. This conformally-coated unit offers a scalable controller solution to address I/O points and it can withstand harsh environmental conditions. It is used to monitor and control I/O access across the ControlLogix backplane and to control local network links. This controller comes with 20 MB of user memory. The controller is efficient and it supports different programming languages including the sequential flow chart, ladder diagram, and functional diagram languages. The 1756-L84EK controller can work with 128,000 total I/O and 4000 analog I/O. The processor draws 5 milliamps and 1.20 Amps of current with 1.2 and 5.1 Volts DC, respectively. The isolation voltage of the controller is 50 Volts continuous with basic insulation from the USB to the  backplane, the USB to the Ethernet, and from the Ethernet to the backplane. It is tested with 1000 Volts for 60 seconds. The controller has a slot width of 1.

For communication, the Allen-Bradley 1756-L84EK controller is equipped with a single USB port that supports communication speeds of up to 12 MB, an Ethernet port that has communication speeds of 10, 100, or 1000 Mbps. The USB port is used for the configuration, programming, and firmware updates of the controller. The 1756-L84EK controller comes with an open enclosure design and it can be installed on any I/O slot of the ControlLogix system. The front side has LED indicators and a 4-character alphanumeric display panel. The surrounding air temperature should be in the 0 to 60 degrees Celsius range for appropriate operation. The controller can handle vibrations of 2 g with 10 to 500 Hertz frequency, and shocks of 30 G for both operating and non-operating conditions.

The Allen-Bradley 1756-L84EK controller is a ControlLogix series industrial controller. It is conformally coated.
