Allen-Bradley 1764-DAT MicroLogix 1500 Data Access Tool

Product Overview

The Allen-Bradley 1764-DAT serves as a specialized operator interface for the MicroLogix 1500 controller platform. This Data Access Tool mounts directly onto the processor, allowing maintenance personnel and operators to monitor and adjust internal data without a separate laptop or HMI. It provides instant visualization of controller status and allows for the modification of integer and bit elements in real-time. We guarantee this unit is 100% Brand New original factory stock, ensuring crystal-clear display contrast and responsive button actuation for your legacy automation systems.

Technical Specifications

The 1764-DAT integrates seamlessly with the MicroLogix 1500 bus, utilizing the following electrical and functional parameters:

Engineering Advantages

• Real-Time Fault Diagnostics: The 1764-DAT displays controller faults instantly on the monochrome screen. This eliminates the need to connect a programming PC to identify simple hardware or software trips, drastically reducing Mean Time to Repair (MTTR) on the plant floor.

• On-the-Fly Parameter Adjustment: This tool permits direct access to 48 integer and 48 bit elements. Operators can adjust timers, counters, or setpoints through the integrated keypad, enabling fine-tuning of machine performance without halting production or modifying the ladder logic.

• Maintenance Flexibility: The module supports "Removal Under Power," allowing technicians to move one 1764-DAT between multiple MicroLogix 1500 processors for troubleshooting. This hot-swappable capability ensures you only need one tool to service an entire bank of controllers.

• Zero-Footprint Installation: The 1764-DAT plugs directly into the front of the 1764-LSP or 1764-LRP processor. It requires no additional DIN rail space or external 24V DC wiring, as it draws its power directly from the MicroLogix backplane bus.

FAQs

• Q: Does the 1764-DAT require external software to function?

• A: No. The tool functions as a plug-and-play device. You define which data elements (bits or integers) are accessible through the standard RSLogix 500 programming environment, but the tool itself operates autonomously once connected.

• Q: Can I leave the 1764-DAT permanently attached to the processor?

• A: Yes. Many engineers leave the unit attached to provide local status monitoring. It features an industrial-grade enclosure that withstands continuous operation within the specified temperature range of 0–55 °C.

• Q: Will this tool work with MicroLogix 1000, 1100, or 1200 models?

• A: No. The 1764-DAT utilizes a physical connection port exclusive to the MicroLogix 1500 (1764) processor series. Other MicroLogix families require different HMI or communication solutions.

• Q: Is this unit a used "pull" from a decommissioned panel?

• A: Absolutely not. We supply only 100% Brand New units. Purchasing new ensures the LCD backlight remains at full brightness and the membrane buttons have not suffered tactile degradation from years of shop-floor use.
