Allen-Bradley 1762-L24BWA Programmable Logic Controller – MicroLogix 1200 Series
Imagine a bottling line halted mid-shift, a conveyor frozen, or a packaging cell throwing fault codes with no clear path to recovery — all because the central controller has failed and no replacement is on hand. In modern industrial environments, the programmable logic controller is not a peripheral device; it is the nervous system of the entire operation. Without a reliable, spec-matched replacement like the Allen-Bradley 1762-L24BWA, every hour of downtime translates directly into lost production, missed delivery windows, and escalating maintenance costs.
The 1762-L24BWA sits at the heart of the MicroLogix 1200 family — Rockwell Automation’s proven mid-range PLC platform trusted across tens of thousands of installations worldwide. With 24 onboard I/O points, relay output capability, and AC power supply input, this controller strikes the optimal balance between compact footprint and robust functionality. It is the go-to choice for OEM machine builders, system integrators, and plant engineers who need deterministic control, broad communication options, and long-term parts availability in a single, field-proven package.

- Expandable I/O Architecture: Support for up to 6 MicroLogix 1762-series expansion modules enables seamless scaling — add analog inputs, thermocouple modules, or additional digital I/O as your application grows.
- Built-In Real-Time Clock: Enables time-stamped data logging, scheduled operations, and shift-based control logic without external hardware.
- High-Speed Counter Inputs: Supports encoder feedback and pulse-train counting for motion-adjacent applications such as conveyor indexing and fill-level measurement.
- RS-232 Multi-Protocol Port: Native support for DF1 Full-Duplex, DF1 Half-Duplex, DH-485, ASCII, and Modbus RTU protocols provides broad SCADA and HMI connectivity out of the box.
- Compact DIN-Rail Form Factor: Optimized for space-constrained control panels; mounts directly on standard 35mm DIN rail.
- Long Product Lifecycle: The MicroLogix 1200 platform has an extensive installed base and Rockwell Automation’s long-term parts support commitment, protecting your maintenance investment.

Frequently Asked Questions
Q: Is the 1762-L24BWA still in production by Rockwell Automation?
A: The MicroLogix 1200 series has reached end-of-life status with Rockwell Automation. However, the platform remains widely installed and supported through authorized spare-parts channels. Konmask.com maintains access to new-surplus and refurbished stock to support ongoing maintenance needs.
Q: What is the difference between 1762-L24BWA and 1762-L24BXB?
A: The primary differences are power supply and output type. The L24BWA uses an AC power supply (100–240V AC) with relay outputs, while the L24BXB uses a DC power supply (24V DC) with transistor (sourcing) outputs. Choose based on your panel power architecture and load switching requirements.
Q: Can I use RSLogix 500 to program the 1762-L24BWA?
A: Yes. RSLogix 500 is the native programming environment for all MicroLogix 1200 controllers. The free RSLogix Micro Starter Lite version supports basic programming; the full RSLogix 500 license is required for advanced features such as online editing and data trending.
Q: How many expansion modules can I connect?
A: The 1762-L24BWA supports up to 6 expansion modules from the 1762 series. Total I/O expansion capacity depends on the module types selected and the controller’s power budget.
Q: Do you provide a warranty on this product?
A: Yes. All units sold by Konmask.com carry a minimum 90-day functional warranty covering defects identified under normal operating conditions. Extended warranty options are available upon request.
Q: Can you assist with cross-referencing to a newer Rockwell platform?
A: Absolutely. Our engineering team can advise on migration paths to the MicroLogix 1400 or CompactLogix 5370 platforms if you are planning a system modernization project.
