The Allen-Bradley 1745-LP101 is a SLC 100 Series processor unit that serves as the central control for a SLC 100 PLC system. It combines a CPU with 16 I/O points (10 input terminals and 6 outputs) and is powered from 85-132 V AC at 50/60 Hz, with battery-backed CMOS RAM memory to retain program data. An EEPROM Memory Module can plug into the processor for program loading and storage. SLC 100 systems support expansion; pairing the LP101 with compatible expansion modules increases I/O capacity up to 112 points, enabling scalable control for small to mid-size automation tasks.
