Allen-Bradley 1747-L532 16-Point Analog Input Module

Allen-Bradley 1747-L532 is a SLC 5/03 System Processor for the SLC 500 family, delivering 16 KB of battery-backed RAM and up to 16,000 words of user memory to support program data and logic in discrete and process-control applications. It supports up to 4,096 digital I/O points and up to 480 local analog I/O points, enabling mixed workloads within a compact backplane. Key performance specs include a 1 ms program scan time and a 0.225 ms I/O scan time, helping maintain responsive control in medium-scale systems. The CPU fits into a 30-slot backplane and can drive up to 3 I/O chassis, with a backplane current capacity of 500 mA at 5 V. Communications options include DH-485 and RS-232 interfaces for programming, monitoring, and network integration. The module is rated for an ambient operating range of 0 to 60 degrees Celsius, suitable for many industrial environments. As a legacy SLC 500 processor, it interoperates with standard Allen-Bradley backplanes and networking hardware, making it a viable option for sustaining or upgrading existing installations that rely on the SLC 500 platform.
