Allen-Bradley 1747-L532 Programmable Logic Controller Module

Allen-Bradley 1747-L532 is a SLC 5/03 CPU Processor for the SLC 500 modular PLC family, delivering 16 KB of memory and supporting DH-485 and RS-232 serial communications for rack networking and programming. As a Series C controller running 1747-OS302 firmware (Series C, FRN 5, 6, or 7), it can handle up to 4096 digital I/O points and up to 480 analog I/O channels, with a typical program scan time around 1 ms, making it suitable for mid-range control tasks, sequencing, timers, and simple analog control in legacy automation setups. It operates from a 5/24 VDC supply and draws up to about 500 mA from the backplane, reflecting the standard power requirements of SLC 500 processors. The 1747-L532 is designed for installation in an SLC 500 rack and remains compatible with common Rockwell Automation communication and programming workflows, enabling reliable operation in discrete and basic analog control applications across manufacturing environments.
