Allen-Bradley 1747-L30C SLC 500 Processor Module

Allen-Bradley 1747-L30C SLC 500 Processor Module is a fixed-I/O CPU for the SLC 500 family, designed to fit in a standard SLC 500 rack and drive up to 30 I/O points. It provides 18 input channels and 12 output channels, enabling compact automation of machines, conveyors, and sensors in light-load control tasks. The module operates on 120/240 VAC power and supports 50/60 Hz, making it compatible with a wide range of industrial power environments. For communication and programming, it offers DH-485 and RS-232 serial interfaces, allowing configuration and diagnostics within legacy SLC networks. The 1747-L30C can be used with a 2-slot expansion chassis to grow I/O capacity as needed, supporting straightforward expansion within existing SLC 500 systems. In a typical setup, it serves as the central controller for simple ladder-logic programs, providing reliable performance in standalone controllers or as part of a broader SLC 500 configuration with additional I/O modules.
