Allen Bradley 1738-ACNR ArmorPoint I/O DeviceNet Network Adapter

Product Overview

The Allen Bradley 1738-ACNR functions as a high-durability interface between a DeviceNet network and ArmorPoint I/O modules. Designed specifically for "On-Machine" applications, this adapter eliminates the need for a separate electrical enclosure by providing a fully sealed, chassis-mounted solution. We supply this module in 100% Brand New, original factory condition, ensuring maximum protection for your decentralized control architecture in the most demanding environments.

Technical Specifications

The 1738-ACNR incorporates ruggedized hardware to maintain network stability under extreme physical stress:

Engineering Advantages

• Extreme Washdown Protection: The IP69K rating ensures the module withstands high-pressure, high-temperature washdown procedures. This capability solves the industry-wide pain point of hardware failure in food, beverage, and pharmaceutical processing areas where sanitation is frequent.

• Reduced Cabinet Costs: Because the 1738-ACNR mounts directly to the machine frame, you eliminate the expense of large control cabinets, cooling systems, and long cable home-runs. This "On-Machine" philosophy speeds up deployment and reduces the total footprint of the automation system.

• M12 Quick-Disconnect Efficiency: The use of industry-standard M12 connectors prevents wiring errors and drastically reduces installation time. Technicians can replace cables or sensors in seconds without opening a junction box, minimizing Mean Time to Repair (MTTR).

• Subnet Scalability: The integrated M12 subnet expansion port allows for modular growth. Engineers can extend the I/O backplane to accommodate additional modules without redesigning the primary network drop, providing high flexibility for machine retrofits.

FAQs

Q: Does the 1738-ACNR require a protective enclosure?

A: No. The 1738-ACNR features a fully sealed design with an IP69K rating. You mount it directly onto the machine's framework, as it resists water, dust, and heavy vibrations without additional shielding.

Q: What is the primary difference between IP67 and IP69K for this module?

A: IP67 protects against temporary immersion in water. IP69K specifically certifies that the module survives high-pressure steam cleaning and jet sprays, making it far superior for sanitary food-grade environments.

Q: Can I expand the number of I/O points connected to this adapter?

A: Yes. The M12 subnet expansion port enables you to link additional ArmorPoint I/O modules, allowing the adapter to manage a distributed cluster of inputs and outputs via a single DeviceNet node address.

Q: Is the 1738-ACNR compatible with standard DeviceNet scanners?

A: Yes. It integrates seamlessly with any Allen Bradley or third-party DeviceNet scanner. You simply configure the node address and baud rate to match your existing network parameters for immediate communication.
