AB 1747-L552 32 K USER MEMORY SLC-5/05 CONTROLLER 32 K USER MEMORY
About 1747-L552 :
The AB 1747-L552 is a processor that is part of AB'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. 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).

Power must be turned off when adding or removing a module. Status LEDs are available for this processor and these let you monitor its current state. The 1747-L552 processor has an open-type enclosure and is mounted via a chassis.
The entire processor measures 145 x 35 x 142 millimeters. The Ethernet connection of this processor is BOOTP enabled and it supports up to 48 incoming or outgoing connections. Outgoing connections can only establish one connection per destination node. Multiple MSG instructions will share the same connection if they use the same destination node.
This processor also has an RS-232 port and a flash backup memory. It has a user-replaceable lithium battery that lasts an average of two years.
The 1747-L552 processor has a capacitor and this lets the processor run for at least 30 minutes using the battery back-up while the battery itself has been disconnected. The battery must be connected to the processor within 30 minutes to avoid losing data in the RAM.
