The Allen-Bradley 1747-L552 is a processor that is part of Allen-Bradley's SLC 500 series of controllers. The 1747-L552 provides users with high bandwidth networking for systems, bringing 10 Mbps Ethernet connectivity to the popular SLC 500 family of programmable controllers.  The 1747-L552 is well-rated for its user-memory backup of 64k in the C series or later.  Additionally, it has a maximum user memory of 32K words total (28K words of information or programmed, 4K words for information only). The processor features 4096 inputs and 4096 outputs.  The 1747-L552 has a standard RAM and a flash backup memory. The 1747-L552 supports communication speeds of 100 Mbps over the Ethernet with Auto-Negotiation, increased Ethernet connections (48 connections for the 1747-L552), and provides HTTP server capabilities.

The 1747-L552 has a built-in 10Base-T Ethernet channel, 10 Mbps communications through support of TCP/IP protocol, and it utilizes many widely available Ethernet devices and cabling. Another great feature of this processor is the availability of online programming over Ethernet with RSLogix 500 Programming Software, and the processor also supports Simple Network Management Protocol (SNMP) for management of your networks. Through the SLC 500 message instruction, the 1747-L552 achieves high-speed peer-to-peer communication. 

Additional features of the 1747-L552 include 3 maximum chassis with 30 slots, LED operating indicators, and a typical scan time of 0.9 ms/K. The processor has power supply loading at 5V dc of 1A and power supply loading at 24V DC of 200 mA.  In case of power loss, the 1747-L552 has a program scan hold-up time ranging from 20 milliseconds to 3 seconds dependent on power supply loading.  Built for industrial environments, the processor has great immunity to noise with the NEMA standard ICS 2-230, ambient operating temperatures ranging from 0-60˚C (32-140˚F) and a storage temperature ranging between -40-85˚C (-40-185˚F).
