Allen-Bradley 1756-L73XT ControlLogix5573 XT Processor with 8MB Memory

Description

The Allen-Bradley 1756-L73XT ControlLogix5573 XT Processor is a member of the Logix 5570 product family, designed as a rugged programmable automation controller (PAC) for harsh industrial environments. Featuring 8MB user memory and 0.98MB I/O memory, it delivers core ControlLogix controller functionality with enhanced environmental resilience, thanks to a protective coating that resists harsh and corrosive conditions. When paired with FLEX I/O-XT components, it operates reliably across a temperature range of -20 to 70 degrees Celsius.

Key electrical specifications include a power draw of 800mA at 5.1V AC and 5mA at 1.2V AC, with a total power consumption of 2.5W and heat dissipation of 8.5 BTU/hr. It offers robust isolation: 30V continuous isolation voltage, plus insulated USB-to-backplane connections tested to withstand 500V AC for 60 seconds. The processor supports both single and high-availability (redundant) configurations, and can handle up to 128,000 digital I/O signals and 4,000 analog I/O signals, enabling both local and distributed I/O topologies. It is compatible with multiple communication protocols, including Ethernet I/P, DeviceNet, ControlNet, Synchlink, Data Highway Plus (DH+), Remote I/O (RIO), and third-party protocols, making it suitable for large-scale factory and process automation applications.
