Product Overview
When a control panel needs a compact PLC that handles 120VAC field devices directly, the Allen-Bradley 1762-L24AWA is a practical answer. Part of the MicroLogix 1200 line, this programmable controller packs fourteen 120VAC inputs and ten relay outputs into a DIN-rail-mount package. It suits oil, gas, and industrial automation panels where AC pilot devices and relay-driven loads are common.

The 14 AC inputs accept 120VAC signals, so you can wire pushbuttons, selector switches, and limit switches without interposing relays. The 10 relay outputs handle 24-125VDC or 120-240VAC loads, giving direct control of solenoids, small contactors, and indicator lamps. The embedded serial port supports DF1, DH-485, ASCII, and MODBUS, which keeps integration with existing control networks straightforward.
Buyer’s Guide: Is the 1762-L24AWA Right for Your Panel?
Start with I/O count and type. Fourteen AC inputs and ten relay outputs fit applications with moderate discrete devices and mixed AC/DC loads. If your panel runs mostly DC sensors or needs high-speed counting, a different MicroLogix 1200 variant may fit better. For AC pilot devices and relay-switched loads, this model is a strong match.
Next, confirm power. The controller runs on 120-240VAC nominal supply. Inrush current reaches 25A for 8 ms at 120VAC and 40A for 4 ms at 240VAC, so size upstream protection and wiring accordingly. Operating temperature spans 0 to 55 degrees Celsius, and the unit should be mounted horizontally in a clean, dry location.
Finally, check communication. The 8-pin mini-DIN port supports DF1, DH-485, ASCII, and MODBUS. If your network uses a different protocol, plan for an external gateway or connection module and confirm cables with your supplier before ordering.
Installation and Maintenance
Mount the 1762-L24AWA horizontally on a DIN rail, leaving clearance for airflow. Wire AC inputs and relay outputs per the manufacturer’s terminal assignments, and keep high-voltage routing separated from communication cabling. For maintenance, inspect terminals periodically for tightness and signs of heat, and keep the enclosure free of dust and moisture. The relay outputs are rated for 20,000,000 mechanical cycles, so contact wear is rarely the first failure point in a well-protected panel.
