The Allen-Bradley 1761-L32AWA is an integrated MicroLogix 1000 PLC controller with built-in digital I/O points. It executes ladder-logic control programs for small-scale automation equipment, collecting field sensor signals and driving actuators to complete sequential interlock and logic control for manufacturing machinery.

This compact all-in-one unit features AC power supply, 20-point input and 12-point relay output, RS-232 communication port and status LED indicators. It is widely used in packaging, conveying and general-machinery automation. It serves as important aftermarket spare for maintenance, overhaul and retrofitting of legacy factory automation control cabinets.
