Product Description

The 1761-L32AWA is designed for small-scale automation tasks where space is at a premium but high I/O count is required. The “32” in the model number signifies its 32 I/O points, and the “AWA” indicates it runs on AC Power, has AC Inputs, and features Relay Outputs. It uses a master-slave communication architecture and is programmed using RSLogix 500 software.

Technical Parameters

Product Advantages

• High I/O Density: Offers 32 points in a very small footprint, making it one of the most efficient “micro” PLCs for its generation.
• Reliable Relay Outputs: The electromechanical relays allow for switching both AC and DC loads with different voltage levels on the same controller.
• Ease of Use: Uses the industry-standard RSLogix 500 programming environment, which is well-documented and familiar to most maintenance engineers.
• Cost-Effective: As an “all-in-one” unit, there is no need to purchase separate power supplies or I/O racks.

Key Considerations & Precautions

• Legacy Status: The MicroLogix 1000 series is End-of-Life (discontinued) by Rockwell Automation. It has been replaced by the Micro800 series. New units are hard to find and expensive; most are sold as “Refurbished.”
• Memory Limits: With only 1K of memory, this PLC is not suitable for complex data handling or large-scale math operations.
• Communication Hardware: Programming requires a specific 1761-CBL-PM02 cable. Modern computers will also need a high-quality USB-to-Serial adapter.
• Relay Life: Mechanical relays have a finite lifespan (number of cycles). For high-speed switching (e.g., several times per second), a transistor-output model is preferred.

Product Applications

The 1761-L32AWA is typically found in simple, standalone machinery:

• Conveyor Control: Simple start/stop logic and jam detection.
• HVAC Systems: Controlling fans, dampers, and pumps based on thermostat inputs.
• Lighting Control: Automated scheduling for industrial facilities.
• Material Handling: Small lift stations or pallet dispensers.
• Packaging: Basic labeling or bag-sealing machines.
