1747-L553 Central Processor Unit module

The 1747-L553 is an SLC 5/05 processor that belongs to the SLC 500 Programmable

Logic Controller (PLC) platform. This controller has the highest memory among the SLC

5/05 category which is 64 KB memory. It has integrated RS32 Sub-D 9-Pin connector for

establishing peer-to-peer communication with locally installed Human Machine Interface

(HMI) or a programming workstation. It also has an integrated Ethernet that is ideally used

for communication over a long distance, minimum of 100 meters at 10/100 mbps transmission

speed. It is also ideal for establishing connection to multiple devices at a time. These Two

(2) port may also be used simultaneously without affecting the processor’s logic execution capability.

This controller is ideal for medium to large scale application, with control requirements

ranging from manual to automatic control of Discrete or analog loops as well as implementing

complex control techniques with the utilization of a wide number of embedded instructions. It

may be used in Factory automation, Process Automation even in motion and position control requirements.

It is also capable of sending Messages to other Allen-Bradley PLC platforms such as PLC 5,

CompactLogix and ControlLogix via a specified communication protocol. Though integrated with

Ethernet and RS232 ports, this processor may be installed with communication adapters such

as Remote I/O (RIO), Data Highway Plus (DH+), DeviceNet and DH485.

It may be installed to any SLC 500 chassis. This processor module has a fixed slot assignment of slot Zero (0).
