Rockwell Allen Bradley 1747-L541 SLC 500 Module

About 1747-L541

The Allen-Bradley 1747-L541 processor is an industrial processor module from the Allen-Bradley/Rockwell Automation SLC 500 series. It is listed in the SLC 5/04 product line within the broader SLC 500 series. The hardware components of the 1747-L541 processor include a memory module, a battery, a jumper, a keyswitch, and LED status indicators.  The battery acts as the backup for the processors’ CMOS RAM. The jumper is an operating system download protection jumper that should not be moved unless the users are updating the operating system firmware in the 1747-L541 processor. The keyswitch is used to change the mode that the 1747-L541 processor is operating in and it is located on the front of the processor directly above the connection ports.

The LED status indicators on the Allen-Bradley 1747-L541 SLC 500 processor are the “RUN” indicator, the “FLT” indicator, the “BATT” indicator, the “FORCE” indicator, the “DH+” indicator, and the “RS-232” indicator. These LEDs make it easy for the users to determine when the 1747-L541 processor is powered on and running properly and they let the users know exactly what kind of errors the processor is experiencing when something goes wrong. The 1747-L541 processor supports the Remote I/O network and it can connect to other devices on this network through a Belden 9463 cable. It also supports backplane voltage ratings of 5 Volts DC or 24 Volts DC, and it can draw 1 Amp of backplane current at 5 Volts DC but no current at 24 Volts DC. Its operating temperature range is 0 to 60 degrees Celsius.

SLC 500 System Overview

The Allen-Bradley SLC 500 is a small chassis-based family of programmable controllers,discrete, analog, and specialty I/O, and peripheral devices. The SLC 500 family deliverspower and flexibility with a wide range of communication configurations, features, andmemory options. The RSLogix 500 ladder logic programming package provides flexibleeditors, point-and-click I/O configuration, and a powerful database editor, as well asdiagnostic and troubleshooting tools to help you save project development time andmaximize productivity.
