About the Allen-Bradley 1747-L541

The Allen-Bradley 1747-L541 is the SLC 5/04 16K Controller, an SLC 500 processor with 16 K words of memory. Rockwell Automation publication 1747-IN009 gives a maximum I/O capacity of 4096 discrete inputs and 4096 discrete outputs, a local system of up to 3 chassis / 30 slots, and a typical scan time of 0.9 ms/K for a 1 K ladder logic program. The same publication lists a 5V dc power supply loading of 1.0 A and 0 mA at 24V dc, although processors made before April 2002 draw 200 mA, so check the label. Rockwell lists the lifecycle status as Discontinued.

What is the 1747-L541 used for?

The processor runs the ladder logic program and controls the I/O in an SLC 500 system, which is built from chassis and slots. It communicates over DH485, RS-232 (DF1, DH-485 or ASCII) and Data Highway Plus, and reaches Ethernet TCP/IP, ControlNet and DeviceNet through the interface modules Rockwell lists. It is programmed with RSLogix 500, and the rated operating temperature is 0...60 °C (32...140 °F).

Lifecycle and successor

Discontinued.
