The Allen-Bradley 1747-L542 is a high-performance SLC 5/04 CPU Controller Processor Module belonging to the renowned Rockwell Automation SLC 500 small chassis-based modular programmable logic controller (PLC) family. Tailored specifically for complex industrial automation, process control, and machine management, this mid-range controller handles heavy ladder logic execution efficiently.
Positioned in Slot Zero of an SLC rack, the 1747-L542 features powerful on-board communication capabilities. The inclusion of a 9-Pin RS-232 port combined with a high-speed DH+ port enables seamless pass-through messaging, legacy networking, and data exchanges with systems like PLC-5 or ControlLogix controllers. Built with physical toggles on the front panel, operators can easily switch between RUN, REM, and PROG modes with a secure manual key switch to guarantee onsite parameter safety.
• High-Speed Execution: Delivers a rapid typical scan time of approximately 0.9 milliseconds per K for real-time industrial processing.
• Dual Integrated Communication Ports: Features a 9-Pin RS-232 port and a Data Highway Plus (DH+) interface, allowing direct connection to computer-based HMIs, SCADA systems, or programming terminals.
• High-Density I/O Capacity: Capable of controlling up to 4,096 discrete inputs and 4,096 discrete outputs.
• Generous 32K Word User Memory: Equipped with 32 KB words of user memory to effortlessly manage complex, data-heavy ladder logic configurations.
• Flexible Expansion & Chassis Design: Supports modular installations across up to 3 chassis or 30 total slots, installing securely into Slot 0 of any standard SLC rack
