Allen-Bradley 1747-L552 SLC 500 PLC Processor Module

Product Description

The Allen-Bradley 1747-L552 is a high-performance programmable logic controller (PLC) processor module belonging to the SLC 500 product family, designed for medium-to-large industrial automation applications requiring reliable and deterministic control. Engineered for rugged industrial environments, this processor features a robust industrial-grade architecture, wide temperature tolerance, and excellent electromagnetic interference (EMI) resistance, ensuring stable operation in harsh factory floor conditions with vibration, dust, and electrical noise. It offers expanded memory capacity and fast instruction execution speeds compared to lower-tier SLC 500 processors, while maintaining full compatibility with the SLC 500 I/O system and Rockwell's RSLogix 500 programming software. The 1747-L552 supports multiple communication protocols for seamless integration with HMIs, SCADA systems, and other PLCs, making it a versatile and cost-effective solution for discrete and process control applications across diverse industrial sectors.

Key Functions

As the core of the SLC 500 PLC system, the 1747-L552 processor executes real-time control logic including discrete ladder logic, sequential function charts (SFC), and analog control algorithms with fast instruction execution speeds (0.8 μs per boolean instruction). It supports up to 4096 digital I/O points and 256 analog I/O points, with expandable memory (32 KB user program memory, 16 KB data memory) for complex control strategies. The module features built-in RS-232 and DH-485 communication ports for connectivity with programming terminals, HMIs, and other SLC 500 processors, and supports optional communication modules for Ethernet/IP, ControlNet, and DeviceNet connectivity. It provides comprehensive diagnostic functions for self-monitoring and fault detection, including memory integrity checks, I/O communication diagnostics, and power supply monitoring, with alarm generation for proactive maintenance. Additionally, it supports online program editing without system shutdown, data logging for process optimization, and password protection to prevent unauthorized access to control logic.

Application Scenarios

The Allen-Bradley 1747-L552 SLC 500 processor is widely deployed in medium-scale industrial automation applications across multiple sectors. In manufacturing industries (automotive, food & beverage, packaging), it controls assembly lines, conveyor systems, and packaging machinery, managing discrete I/O for sensor/actuator control and analog I/O for temperature/pressure regulation. In water and wastewater treatment plants, it oversees pump station control, valve actuation sequences, and water quality monitoring systems, with sufficient memory for complex sequencing logic. For material handling and logistics operations, it controls automated storage and retrieval systems (AS/RS), conveyor networks, and palletizing robots in distribution centers. The processor is also ideal for HVAC and building automation systems, managing temperature, humidity, and air handling units in commercial and industrial facilities. Additionally, it is used in power generation auxiliary systems (boiler feedwater control, cooling tower operation), in mining equipment control (crusher and screening plant automation), and in pharmaceutical manufacturing for batch process control and compliance reporting.
