Engineering Advantages

The 1738-AENT optimizes decentralized control strategies by solving harsh-environment connectivity issues:

Elimination of Control Cabinets: The IP69K-rated sealing allows engineers to mount this adapter directly on the machinery. This drastically reduces wiring costs and simplifies the mechanical footprint of the system.

Resilience Against High-Pressure Washdowns: The hardware survives the intense high-temperature, high-pressure cleaning cycles common in food, beverage, and pharmaceutical processing. It prevents moisture ingress that typically causes short circuits in standard PLC components.

Simplified Network Commissioning: The module supports BootP/DHCP for rapid IP address assignment. This feature speeds up initial setup and reduces the time required for device replacement during maintenance windows.

Shock and Vibration Mitigation: Unlike standard rack-mounted adapters, the 1738-AENT architecture absorbs the mechanical stress of machine-mounted environments, preventing intermittent communication drops in heavy-duty applications.

FAQs

What is the significance of the IP69K rating for the 1738-AENT?

The IP69K rating confirms that the module withstands high-pressure (up to 1450 psi) and high-temperature (80°C) washdowns. This makes it ideal for sanitary environments where equipment requires frequent, aggressive cleaning.

Does this adapter support a specific number of I/O modules?

Yes. The 1738-AENT manages up to 63 ArmorPoint I/O modules, though the actual limit may depend on the total power consumption and network traffic requirements of your specific configuration.

Is this a Brand New unit or a surplus item?

We guarantee this 1738-AENT is 100% Brand New. Even though the manufacturer has discontinued the series, our new stock ensures you receive a component with zero wear and full original performance specifications.

Which connectors do I need for the EtherNet/IP ports?

The 1738-AENT typically utilizes M12 D-coded connectors for Ethernet and 7/8-inch (Mini) or M12 connectors for power, ensuring a waterproof seal that maintains the module's IP rating.
