Allen-Bradley 1747-L553 SLC 500 CPU Processor

The Allen-Bradley 1747-L553 is a SLC 5/05 CPU module in the SLC 500 family, delivering 64K words of user memory for program and data storage in a compact, rack-mountable CPU. It provides Ethernet 10BASE-T networking and RS-232 communication, enabling RSLogix 500 programming and networked device communications via both Ethernet and serial connections. Firmware revision FRN 7 accompanies performance specs that include a 0.9 ms program scan time and a 0.225 ms I/O scan time, with support for up to 4,096 discrete inputs and 4,096 discrete outputs, and an ambient operating range of 0 to 60 C. This processor is suited for modular SLC 500 systems requiring a 5/05 CPU with onboard Ethernet and serial communications to connect to HMIs, PLCs, and other networked devices.
