Allen-Bradley 1745-LP101 Programmable Controller

Allen-Bradley 1745-LP101 SLC 100 Programmable Controller is the 16-point CPU module in the SLC-100 family, delivering 10 inputs and 6 outputs in a single processor unit for compact discrete-control tasks. It is powered from 85–132 V AC (50/60 Hz) and uses battery-backed CMOS RAM to retain the control program during power interruptions, helping protect logic and settings in environments with unstable power. A built-in Auto/Manual switch provides straightforward handover between automatic operation and manual control, a feature commonly used during setup or maintenance. Programming follows the familiar ladder logic paradigm used by SLC-100 controllers, making it part of the broad Rockwell Automation SLC-100 ecosystem for simple, reliable control. The LP101 variant designation indicates the 16-point I/O configuration, making it appropriate for compact control tasks in small-scale automation projects where a single processor with integrated I/O is sufficient.
