Product Overview: 1747-L532/E SLC 5/03 Processor
The Allen-Bradley 1747-L532/E is a Series E SLC 5/03 processor for the SLC 500 modular platform. It provides 16K words of user memory and installs in slot 0 of a 1746 chassis. Because the 1747-L532/E is discontinued as of 2024-03-31, each remaining unit represents a cost-effective path to extend the service life of an existing SLC 500 installation without a full platform migration.
Key Specifications of the 1747-L532/E
- User memory: 16K words for program and data storage.
- Communication ports: one DH-485 port and one RS-232 port.
- I/O capacity: supports up to 4096 I/O points.
- Backplane supply: 24V DC via the 1746 chassis backplane.
- Scan time: 1 ms/K for deterministic control execution.
- Operating temperature: 0 to 60 C.
- Chassis compatibility: 1746-A4, -A7, -A10, and -A13, panel-mount.
The 1 ms/K scan time directly reduces machine cycle variance, which in turn lowers scrap and rework costs on high-throughput lines. The 24V DC backplane architecture also keeps field wiring simple and reduces external power supply count.
Cost Implications of the 1747-L532/E Platform
Because the 1747-L532/E draws logic power from the 1746 chassis backplane, no separate 5V DC logic supply is required. Consequently, panel build cost and wiring labor decrease. The 16K word memory capacity supports moderately complex programs without immediate hardware upgrades, which defers capital expenditure. Additionally, the DH-485 and RS-232 ports allow existing operator interfaces and programming terminals to remain in service, avoiding replacement cost.
Integration and Compatibility Notes
The 1747-L532/E operates in slot 0 of a 1746 chassis. It is not hot-swappable; therefore, always remove power before installation, removal, or wiring. The DH-485 port supports multi-drop networks, while the RS-232 port serves programming and point-to-point communication. When integrating into a plant network, confirm cable and gateway requirements with the supplier. Field-side load power for I/O modules requires an external supply.
Maintenance and Reliability Considerations
Periodic inspection of terminal connections and chassis ventilation helps maintain reliable operation. Because the 1747-L532/E is discontinued, stocking spare processors reduces unplanned downtime cost. The 0 to 60 C operating range suits most industrial environments, provided humidity remains between 5 and 95 percent non-condensing.
