Product Summary
The 1747-L553 SLC 5/05 processor delivers the highest memory in its class. This unit controls up to 4096 inputs and outputs. It integrates Ethernet and RS-232 ports for versatile communication. Engineers use this CPU for complex discrete and process control tasks.
Expert Technical Evaluation & Performance Review
The 1747-L553 module operates as a central processing unit for the SLC 500 platform. It provides a user memory of 64,000 words for robust program execution. This processor executes a program scan time of just 0.9 ms per kiloword. Its I/O scan time completes in only 0.225 milliseconds for rapid response.
This CPU supports a maximum of 30 module slots across 3 local chassis. It handles up to 480 local analog I/O points for precise control. The module uses battery-backed RAM to retain critical data during power loss. An optional 1747-M13 memory module provides an additional 64K of storage.
The integrated Ethernet port operates at 10/100 Mbps for fast data transfer. This port enables communication over distances up to 100 meters. The RS-232 port allows direct connection to an HMI or programming workstation. Both ports function simultaneously without degrading logic execution performance.
This processor includes an advanced instruction set based on the PLC-5 platform. It supports online programming and flash memory upgrades for easy updates. The built-in real-time clock and calendar provide accurate time-stamping for events. A key-switch offers three positions for mode selection and security.
The 1747-L553 communicates with other Rockwell platforms like ControlLogix and CompactLogix. It can send messages via specific protocols to PLC-5 controllers. Additional communication adapters support Remote I/O and DeviceNet networks. This flexibility makes the module ideal for distributed SCADA system architectures.
This controller operates reliably in temperatures from 0 to 60 degrees Celsius. It withstands a 30G operating shock for demanding industrial environments. The module draws 1 Amp at 5 Volts DC from the backplane. Its bit-instruction execution time is a fast 0.37 milliseconds for efficient logic.
Product Procurement & Buyer Guide
Procurement teams should verify the 1747-L553 fits their existing SLC 500 chassis. This processor must occupy slot zero for correct system configuration. It supports up to 3 local I/O chassis for scalable system expansion. Engineers can install up to 30 module slots across these chassis.
The 1747-L553 requires a 1747-BA battery for memory backup during power outages. Users should order the 1747-M13 memory module for additional storage capacity. This CPU works with the 1761-NET-AIC converter for advanced network connections. It supports Remote I/O and DeviceNet scanner modules for expanded I/O control.
This processor is ideal for medium to large scale automation applications. It handles manual to automatic control of discrete and analog loops. The unit implements complex control techniques using numerous embedded instructions. It suits factory automation, process control, and motion control requirements.
The module has a fixed slot assignment and cannot be moved to other positions. Its backplane current draw is 1 Amp at 5 Volts DC only. The unit does not draw any current at 24 Volts DC. This specification helps engineers calculate total power supply requirements accurately.
Buyers should confirm the operating environment is clean and dry. The 1747-L553 operates within a 0 to 60 degrees Celsius temperature range. It withstands a 30G operating shock for reliable performance. These environmental tolerances ensure long-term durability in industrial settings.
