1734-ACNR | Allen Bradley | POINT I/O ControlNet Adapter Module

Product Overview

The Allen Bradley 1734-ACNR functions as a high-performance communication interface for the POINT I/O™ platform. This adapter enables seamless data exchange between a ControlNet network and up to 63 POINT I/O modules. We supply this unit as 100% Brand New and Original, featuring dual BNC connectors to support redundant media topologies. It bridges the gap between your central controller and distributed field devices, ensuring deterministic I/O performance in complex automation architectures.

Technical Specifications

The 1734-ACNR manages power distribution and network traffic within the following parameters:

Engineering Advantages

• Redundant Media Support: The 1734-ACNR features dual BNC ports. If the primary ControlNet cable sustains damage or signal loss, the adapter instantly switches to the redundant path. This prevents system downtime and maintains continuous process control.

• High-Density Power Management: An integrated power supply provides 1000 mA of POINTBus current. This capacity allows the adapter to power a significant number of I/O modules directly from the backplane, reducing the need for additional 1734-EP24DC expansion power supplies.

• Rugged Electrical Protection: Built-in reverse polarity protection prevents hardware failure during installation errors. The module also handles high inrush currents (up to 6A), ensuring stability during system power-up cycles in large-scale industrial racks.

• Deterministic Networking: ControlNet protocol ensures that time-critical I/O data arrives exactly when the processor expects it. This eliminates network jitter, which is essential for high-speed packaging or assembly lines.

• Tool-Free Installation: The module snaps directly onto a standard DIN rail. Its compact vertical orientation saves significant cabinet space, making it ideal for distributed junction boxes where interior room is limited.

FAQs

• What is the maximum number of I/O modules this adapter can support?

  The 1734-ACNR supports up to 63 POINT I/O modules. However, you must calculate the total current draw to ensure it does not exceed the 1000 mA POINTBus limit.

• Does this unit arrive in original factory packaging?

  Yes. We guarantee this 1734-ACNR is 100% Brand New and Original. It ships in the manufacturer's sealed box with the unique GTIN (10612598283702) and quality control stamps intact.

• Can I use this adapter in a non-redundant ControlNet setup?

  Yes. While the "R" in ACNR stands for Redundant, the module functions perfectly in a single-cable configuration. Simply connect your network to Port A and leave Port B available for future expansion or redundancy.

• What type of power supply should I use for the input voltage?

  Use a regulated 24V DC power supply. Ensure the supply can handle the 6A inrush current to prevent voltage drops during the initial power-on sequence.
