Rockwell Automation has made two additions to its Allen-Bradley ControlLogix family of controllers, both leveraging the single design environment and networking protocol within the company's integrated architecture system. The ControlLogix L73 and L75 programmable automation controllers (PACs) provide advanced memory, speed and processing capabilities for a wide range of control demands, from high-performance logic and motion to information-intensive process applications.
For complex, high-performance motion applications, the ControlLogix L73 and L75 PACs interface seamlessly with motion drives through EtherNet/IP and SERCOS network interfaces. The controllers are capable of supporting as many as 100 axes, designed to further simplify synchronization of complex motion applications.
The 1 GB secure digital card that ships with each controller can provide improved data integrity and faster reads and writes than previous CompactFlash technology. The ControlLogix L73 PAC is suited for users requiring up to 16 MB of memory while the ControlLogix L75 PAC offers 32 MB of memory.
New energy storage modules that ship with each controller will eliminate the need for lithium batteries. A USB port is designed to provide faster uploads and downloads, firmware upgrades and online edits. The controllers feature an on-board display to provide enhanced controller diagnostics and run-time information. Both models are currently available for shipping.
