About 1747-L552:

TheAB 1747-L552is an SLC 500 modular processor.This module has amaximum user memory of 32K words, with 28K words for the data or program and 4K wordsfor the data only. The processor also has an absolute maximum number of I/O at 4096 each,forboth inputs and outputs. It also has a maximum local analog of 480. One hundred and sevenprogramming instructions, as well as three chassis and thirty slots, are available with this processor; this unit maximum current of 1A at 5 Volts DC and 0A at 24 Volts DC. It comes with a typicalprogram scan time of 0.9 milliseconds/K, an I/O scan time of 0.225 milliseconds, and an XIC bit execution of 0.37Ohms. Depending on the power supply loading, this processor has a program scan hold-up time of 20 milliseconds to 3s seconds after a loss of power. It has an operating vibration of 0.015 inches, a peak-to-peak displacement at 5 to 57 Hertz, and 2.5G acceleration at 57 to 2000 Hertz. This processor also has an operating shock of 30G and a non-condensing relative humidity of 5 to 95%. The operating temperature range of this processor is 0 to 60 degrees Celsius and the storage temperature range is -40 to 85 degrees Celsius.

The only compatible memory module for this processor is the M13 for the Series C OS501 or higher firmware version. 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 48incomingor outgoing connections. You can also configure the processor manually using the RSLogix 500 programming software, aside from a BOOTP/DHCP request. Do note that 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-232port 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 thebattery 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.
