The 1761-L20AWA-5A MicroLogix 1000 Controller from Rockwell Automation is a compact 20-point programmable logic controller (PLC) designed for small-scale industrial automation and OEM machine control applications.
This controller combines:
- CPU
- Power supply
- Digital I/O
- Analog I/O
- Communication interface
into a single compact housing, making it ideal for space-saving automation systems.
The 1761-L20AWA-5A features:
- 12 × 120V AC digital inputs
- 8 relay outputs
- 4 analog inputs
- 1 analog output
- Built-in RS-232 DF1 communication
It is commonly used in packaging machines, conveyors, HVAC systems, pump stations, and general industrial automation systems. The model has been officially discontinued by Rockwell Automation but remains widely used in legacy systems.
