Order now the 2080-LC50-24AWB, a professional-grade 24-point controller from the Allen-Bradley Micro850 series. This PLC is uniquely designed for applications requiring 120V AC inputs and relay outputs, providing a direct interface to high-voltage industrial control signals without the need for interposing hardware.
What Is the 2080-LC50-24AWB?
The 2080-LC50-24AWB is a high-performance programmable logic controller intended for large-scale standalone machine control and distributed I/O systems. It features 14 inputs rated for 120V AC and 10 relay outputs. Unlike the Micro830, the Micro850 series includes an integrated 10/100 Base-T Ethernet port, making it a «Connected Enterprise» ready device. It supports EtherNet/IP for peer-to-peer messaging and remote programming. Its architecture is highly expandable, supporting up to three 2085-series expansion I/O modules in addition to three 2080-series plug-in modules. This makes the 2080-LC50-24AWB an incredibly flexible platform for building automation, HVAC, and power management applications where 120V AC logic is the plant standard.

Industrial Connectivity and Expansion
The 2080-LC50-24AWB is engineered for connectivity. The embedded Ethernet port allows for seamless integration into factory networks, supporting communication with HMI, SCADA, and other PLCs. Its expansion capability is its greatest strength; by adding 2085 expansion modules, the I/O count can be increased significantly while maintaining the same control logic. The architecture also supports Automatic Device Configuration (ADC) in some configurations, facilitating easy module replacement. This controller is perfect for retrofit projects where legacy 120V AC field devices are still in use, providing a modern, networked brain for older machine designs.
Installation Advice
When installing the 2080-LC50-24AWB, pay close attention to the separation of AC input wiring and low-voltage communication cables. High-voltage AC lines can induce noise into the Ethernet and Serial buses. Ensure the PLC is mounted on a grounded DIN rail to provide a reference for the internal surge protection components. Since this model includes an internal 120/240V AC power supply, verify that the supply voltage is stable and within the ±15% tolerance to prevent intermittent power cycles or processor resets.
Frequently Asked Questions
Q: Does the 2080-LC50-24AWB support high-speed counters?
A: No. Because this module uses 120V AC inputs, it is not suitable for high-speed pulse detection. For HSC tasks, a 24V DC input model (QBB/QWB) is required.
Q: Can I use 2085 expansion modules with this PLC?
A: Yes, the Micro850 series is specifically designed to support the 2085 line of high-density expansion I/O, allowing you to scale the system as your machine requirements grow.
