Overview
The Allen-Bradley 1761-L16AWA is a compact programmable logic controller (PLC) in the MicroLogix 1000 series, designed for small to mid-sized industrial automation and discrete control applications. This controller features 16 total I/O channels, with 10 AC input points and 6 relay output points. It includes an EEPROM memory with 1K capacity, supporting approximately 737 instructions and 437 data words. The unit is powered by an AC source rated 85-264VAC, making it compatible with standard industrial power supplies.
