1756-L72SK

|

The 1756-L72SK controller is one of the GuardLogix and ControlLogix controllers that are available from Allen-Bradley/Rockwell Automation. Because it is both a GuardLogix and a ControlLogix controller, the 1756-L72SK controller can handle safety applications and functions as well as standard controller applications and functions. It cannot be used as part of a controller redundancy system but can be connected to a compatible safety partner module. The 1756-L72SK controller can be installed in any available slot in a module chassis, but if it is used with a safety partner module, the safety partner module needs to be installed in the slot immediately to the right of it. The 1756-L72SK controller has a rated current draw of 5 milliamps at 1.2 Volts DC and 800 milliamps at 5.1 Volts DC.
