Allen-Bradley 1745-LP151 Programmable Logic Controller Module

Allen-Bradley 1745-LP151 is a SLC 150 PLC processor module that combines compact control with built-in I/O capacity for small to mid-size automation tasks. It provides 20 sinking 85-132 VAC (or 170-265 VAC) inputs, 10 AC triac outputs, and 2 relay outputs, all powered from a 50/60 Hz supply. The controller stores user programs in CMOS RAM with 1200 words of memory and supports program backup/load via the optional 1745-M1 EEPROM memory module. A typical scan time of 4 milliseconds supports responsive sequencing and discrete control in industrial applications. Operating temperature range is 0 to 60 C, with storage from -40 to 85 C, and humidity tolerance of 5 to 95% non-condensing. This LP151 processor is used within the SLC 150 family as a standalone controller or in conjunction with expansion options to suit compact automation systems requiring straightforward logic, timing, and I/O virtualization without external power supplies.
