The Allen-Bradley 1745-LP101 is a sophisticated member of the SLC 100 programmable controller series, designed to efficiently handle industrial computations with its array of integrated features such as relays, timers, shift registers, and counters. With its user-friendly ladder diagram format, this PLC excels in applications like material handling and machine tool operations. The unit offers a built-in auto/manual switch for seamless recovery after power losses, an electrical disconnect to guard against power surges, and the capability to expand I/O capacity through a dedicated expansion port, all while operating within a robust range of 85-132V AC at 50-60 Hz.
