1756-L73SK

The 1756-L73SK controller is a 5570 series GuardLogix controller manufactured by Allen-Bradley. Its voltage and current ratings are 800 milliamps at 5.1 Volts DC and 5 milliamps at 1.2 Volts DC. Its memory specifications are 8 megabytes of user memory, 4 megabytes of safety memory, 0.98 megabytes of input/output memory, and 1 Gigabyte of non-volatile SD memory. It weighs 55 pounds and it features a non-removable capacitor energy storage module. The 1756-L73SK controller combines the high-performance input/output control, monitoring, and communication capabilities of ControlLogix controllers with state-of-the-art safety features to provide improved motion system performance.

The 1756-L73SK GuardLogix controller is designed to work with an Allen-Bradley 1756-L7SP or 1756-L7SPK safety partner which must be installed next to it on the ControlLogix chassis. This controller supports motion integration through analog options, a SERCOS interface, or an Ethernet/IP network. It has full support for Networked Safe Torque Off for drives and Kinetix devices. The 1756-L73SK controller also supports any combination of motion axes for the following axes types: generic, CIP, virtual, potion loop drives, Servo, and Servo drive axes. The system status indicator of the 1756-L73SK GuardLogix Controller is an LED display unit. The conformal coating of this controller allows for it to be used in hazardous environments and its operating temperature range is from 0 to 60 degrees Celsius. This module has 20 outgoing unconnected messaging buffers that are used to send service messages within applications and it has 4 incoming buffers. The outgoing buffers are configurable to 40 buffers and the controller features instruction-based alarms (ALMA, ALMD) for fault conditions.
