Machine & Process Automation Solution — Allen-Bradley 1764-24BWA | MicroLogix 1500 Series
Where This Product Is Used
The Allen-Bradley 1764-24BWA MicroLogix 1500 is a compact, high-performance programmable logic controller deployed across a wide range of industrial automation environments. Engineers and system integrators specify this controller for:
- Discrete Machine Control — Assembly lines, stamping presses, injection molding machines, and CNC auxiliary control panels requiring reliable I/O sequencing and ladder logic execution.
- Conveyor & Material Handling Systems — Sortation conveyors, accumulation lines, and palletizing stations where deterministic scan times and robust digital I/O are critical.
- HVAC & Building Automation — Air handling units, chiller plant sequencing, and pump control panels in commercial and industrial facilities.
- Packaging Machinery — Form-fill-seal machines, labelers, and case erectors requiring coordinated motion and sensor integration.
- Water & Wastewater Treatment — Pump stations, chemical dosing systems, and filtration control panels operating in harsh environments.
- Food & Beverage Processing — Mixing, batching, and filling lines where washdown-rated I/O and recipe management are required.
- OEM Panel Builders — Compact control panels where DIN-rail footprint, integrated power supply options, and broad communication support reduce BOM complexity.

Why Engineers Specify This Model
- Relay Output Durability — The 24BWA’s relay outputs handle resistive and inductive AC/DC loads without external interposing relays, reducing panel wiring cost and failure points.
- AC Power Input — Direct 100–240V AC supply eliminates the need for a separate 24V DC power supply in many panel designs, saving space and cost.
- Dual Serial Ports — Simultaneous HMI communication on Channel 0 and Modbus RTU or DH-485 network on Channel 1 without additional communication modules.
- Modular Expansion — Up to 8 expansion I/O modules (1762-series) support analog, thermocouple, RTD, and specialty I/O for complex process applications.
- RSLogix 500 / Studio 5000 Compatibility — Familiar programming environment for Rockwell-trained engineers; extensive function block and ladder logic library.
- Long Product Lifecycle — Rockwell Automation’s extended support commitment makes this platform a safe long-term investment for OEM machine builders.

Application-Specific FAQ
Q: Can the 1764-24BWA operate without the 1764-LRP processor module?
A: No. The 1764-24BWA is a base unit only. The 1764-LRP (or 1764-LSP) processor module must be installed to execute a user program. The base unit provides I/O, power supply, and communication ports.
Q: What is the maximum number of expansion I/O modules supported?
A: The MicroLogix 1500 supports up to 8 expansion modules from the 1762-series, providing up to 256 additional I/O points depending on module selection.
Q: Is Modbus TCP supported natively?
A: The 1764-24BWA supports Modbus RTU over the serial ports natively. Modbus TCP requires an Ethernet communication module (e.g., 1761-NET-ENI) added to the system.
Q: Can this controller be used in a Class I, Division 2 hazardous location?
A: The standard 1764-24BWA is rated IP20 and is not certified for hazardous locations. For Div 2 applications, consult Rockwell Automation for approved enclosure and purge/pressurization solutions.
Q: What programming software is required?
A: RSLogix 500 (v8.0 or later) is the standard programming environment. RSLogix Micro (free) supports basic ladder logic. Both are available from Rockwell Automation’s Software Portal.
Q: Do you provide warranty on used or refurbished units?
A: All units sold by Konmask carry a 90-day functional warranty. Extended warranty and repair services are available — contact us for details.
