Allen-Bradley 1747-L552 SLC 5/05 CPU Processor Module

Allen-Bradley 1747-L552 is an Ethernet-enabled SLC 5/05 CPU module for the SLC 500 family, delivering 32,000 words of user memory and dual-channel communication that includes a built-in RS-232 port and a 10BASE-T Ethernet interface. It supports up to 4,096 inputs and 4,096 outputs, enabling a sizable discrete I/O footprint within a backplane system. The processor offers a typical program scan time of 0.9 milliseconds and an I/O scan time of about 0.225 milliseconds, providing mid-range performance for automation tasks. Channel 0 RS-232 supports DF1, DH-485, or ASCII protocols, while the Channel 1 Ethernet port enables network connectivity for remote monitoring, HMI integration, and data exchange in legacy or retrofitted control environments.
