1734-ADN | Allen-Bradley POINT I/O DeviceNet Adapter Module Supplier

Introduction to the 1734-ADN DeviceNet Adapter Module

When implementing distributed I/O in industrial automation, the 1734-ADN from Allen-Bradley provides a reliable communication interface. This POINT I/O DeviceNet adapter module mounts on a DIN rail and connects up to 63 I/O modules to a DeviceNet network. With a compact design and low-density I/O capability, it suits applications requiring flexible, space-saving control.

Manufactured by Rockwell Automation, the 1734-ADN operates on 23 Volts DC input voltage and consumes 8.1 Watts of power. Its integrated DeviceNet port supports communication rates of 125K, 250K, or 500K bits/second, enabling seamless data exchange with a master controller.

Key Features & Technical Specifications

• Module Type: DeviceNet Adapter Module for POINT I/O systems.
• Input Voltage: 23 Volts DC, with a field side power draw of 400 milliamps.
• Inrush Current: 6 Amps during startup.
• Power Consumption: 8.1 Watts, with a power dissipation of 2.8 Watts at 28.8 Volts.
• POINTBus Current: 1000 milliamps to power connected I/O modules.
• I/O Capacity: Supports up to 63 powered modules and 504 I/O points maximum.
• Communication Rate: Selectable 125K, 250K, or 500K bits/second via DeviceNet.
• Location: Installed on the left side of a 1734 system.

A standout specification is the 504 maximum I/O points, which allows the 1734-ADN to handle large-scale distributed I/O configurations without requiring additional adapters. This reduces system complexity and installation costs.

Industry Applications & Use Cases

The 1734-ADN is ideal for manufacturing lines, material handling, and process control where distributed I/O is essential. For instance, in a packaging facility, this adapter can link multiple POINT I/O modules to a central PLC via DeviceNet, enabling real-time monitoring of sensors and actuators. Its ability to support up to 63 modules makes it suitable for expanding systems without redesigning the network.

Installation & Setup Guide

Mount the 1734-ADN vertically on a DIN rail by applying firm pressure until the locking mechanism engages. Attach the DeviceNet plug to the terminal and tighten the holding screws on both sides. Configure the module address using the embedded thumbwheel switch, with valid addresses from 0 to 63. The module uses this address as default on power-up. Ensure the backplane baud rate and subnet I/O module addresses are set correctly for efficient communication with DeviceNet masters.

Maintenance & Reliability Tips

Regularly inspect the 1734-ADN for loose connections or environmental contaminants. The module performs a self-test on power-up, checking program and internal memories, including status LEDs. The Auto Device Replace (ADR) feature automatically transfers configuration parameters to a replacement module, reducing downtime. For optimal reliability, follow the manufacturer's guidelines for periodic inspection.

Compatibility & Integration

The 1734-ADN integrates seamlessly with POINT I/O modules on its local bus and communicates via DeviceNet to any compatible master controller. It supports AutoBaud detection, which automatically matches the network baud rate from 125K to 500K bits/second. This adapter is designed for the left side of a 1734 system and works with up to 63 I/O modules, making it a versatile choice for new or existing DeviceNet networks.
