Information About 1747-L531
The 1747-L531 is part of the SLC 5/03 processor series from Allen-Bradley, providing an 8K-word memory structure divided between logic and data storage. It supports a maximum of 4096 inputs and 4096 outputs, enabling large system configurations through its multi-chassis architecture. The controller features dual communication channels: Channel 0 for DF1/ASCII/DH-485 and Channel 1 dedicated to DH-485 networking, offering flexible integration with HMIs, programming terminals, and distributed I/O. It includes battery-backed RAM and flash storage for program retention, and supports advanced functions such as remote I/O scanning using 1747-SN or DeviceNet control via 1747-SDN. With fast scan performance, robust electrical isolation, and environmental ratings suitable for industrial use, the 1747-L531 remains a dependable processor for legacy systems and long-term automation support.
Key Features:
- 8K User Memory: Provides 4K words for logic and 4K words for data, supporting moderately complex control programs.
- Dual Communication Ports: Includes DH-485 and DF1/ASCII communication for networked devices and programming access.
- Scalable Architecture: Supports up to 30 module slots per chassis and three local chassis for high I/O density.
- High I/O Capacity: Accommodates up to 4096 inputs and 4096 outputs, including up to 480 local analog points.
- Programmability & Backup: Battery-supported RAM and flash memory options ensure program retention and simple recovery.
- Electrical Protection: Offers 500 VDC channel isolation and 1500 VAC backplane isolation for system safety.
- Industrial Durability: Rated for operation from 0–60 °C with vibration and shock resistance appropriate for plant environments.
- Flexible Expansion: Compatible with modules such as 1747-SN (remote I/O) and 1747-SDN (DeviceNet) to extend system capabilities.
The 1747-L531 provides stable, expandable control performance required for industrial processes and legacy SLC 500 automation systems.
