About the Allen-Bradley 1747-L552

The Allen-Bradley 1747-L552 is the SLC 5/05 32K Controller, a processor with 32 K words of memory. Rockwell Automation publication 1747-IN009 gives a maximum I/O capacity of 4096 discrete inputs and 4096 discrete outputs, and a local system of up to 3 chassis and 30 slots. The same publication lists 107 programming instructions, a typical scan time of 0.9 ms/K for a 1 K ladder logic program, and bit execution (XIC) of 0.37 µs. Rockwell lists the lifecycle status as Discontinued, and the processor is programmed with RSLogix 500.

What is the 1747-L552 used for?

The 1747-L552 is the processor in an SLC 500 system. It runs the ladder logic program and handles the discrete inputs and outputs in the local chassis, and it communicates over DH485, RS-232 (DF1, DH-485 or ASCII) and Ethernet TCP/IP. Rockwell's publication 1747-IN009 rates it for operation at 0...60 °C (32...140 °F) and 5 to 95% humidity without condensation, which sets the conditions of the installation.

Lifecycle and successor

Discontinued.
