The Allen-Bradley 1747-L532 SLC 500 CPU Processor is a SLC 5/03 controller with 16K words of memory designed for DH-485 networks and RS-232 serial communication. It provides 4,096 inputs and 4,096 outputs, and a program scan time of 1 millisecond, enabling responsive control of small to mid-size automation tasks. Built-in DH-485 and RS-232 ports enable data exchange with other SLC-500 devices or programming tools, with Flash-based backup memory and an operating range of 0 to 60 C. Installed in a compatible SLC 500 chassis, the CPU supports up to 30 module slots and draws up to 500 mA from the backplane for stable operation.
