Product Overview
The Allen-Bradley 1734-ADNX is a POINT I/O DeviceNet Adapter Module designed to bridge POINT I/O modules with DeviceNet networks. As a starter module, it installs on the left side of a 1734 system and acts as both a scanner/master for subnet modules and a slave to DeviceNet masters. This dual role ensures seamless data exchange and control in distributed automation architectures.
Part of the POINT I/O series, the 1734-ADNX supports I/O and explicit connections, using I/O mapping to define data flow. Its Auto Start Mode simplifies commissioning, while the Auto Catalog Replace feature prevents errors when backplane modules are swapped incorrectly. With a 24 Volts DC input and a power consumption of 8.1 Watts, this adapter delivers reliable performance in demanding industrial environments.

The 24 VDC input voltage aligns with standard industrial control voltages, ensuring compatibility with existing power infrastructure. The 400 mA field-side power supports connected sensors and actuators, while the 6 A inrush current capability handles momentary surges during startup. The 1000 mA POINTBus current provides ample power for multiple I/O modules, and the 8.1 W power consumption keeps energy costs low.
Industry Applications
The Allen-Bradley 1734-ADNX excels in applications requiring distributed I/O control over DeviceNet. Common use cases include:
-
Manufacturing Assembly Lines: Coordinate sensors and actuators on a production line, where the adapter's master/slave capability enables efficient data collection and control.
-
Material Handling Systems: Manage conveyor controls and sortation equipment, leveraging the adapter's reliable communication to reduce downtime.
-
Process Automation: Integrate POINT I/O modules into a DeviceNet network for monitoring and controlling process variables, ensuring accurate data acquisition.
In each scenario, the 1734-ADNX provides a dependable link between the control system and field devices, contributing to improved operational efficiency.
Installation & Setup Guidance
Installing the 1734-ADNX is straightforward. Mount the adapter at the leftmost position of a 1734 system and connect it to the DeviceNet network. Use a Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV) power supply with a 24 VDC nominal rating to meet CE Low Voltage Directives. Ensure proper termination and grounding per DeviceNet guidelines to avoid communication errors. The adapter's status indicators—3 red/green for network status and 2 green for power—simplify diagnostics during setup.
Maintenance & Reliability
Routine maintenance of the 1734-ADNX involves periodic inspection of the status LEDs and checking for loose connections. The adapter's robust design minimizes failure points, but environmental factors like extreme temperatures or humidity can affect performance. Keep the enclosure clean and ensure adequate ventilation. By proactively monitoring the adapter's health, you can prevent unexpected downtime and extend service life, reducing total cost of ownership.
Compatibility & Integration
The 1734-ADNX is fully compatible with POINT I/O modules and DeviceNet devices. It supports both I/O and explicit connections, making it versatile for various control architectures. The adapter integrates seamlessly with Rockwell Automation controllers that support DeviceNet, such as CompactLogix and ControlLogix. Its ability to reside on both the subnet and primary DeviceNet network allows for flexible system design.
Buying Guide
When purchasing the Allen-Bradley 1734-ADNX, verify the part number and ensure it matches your system requirements. Check the input voltage and power specifications against your existing power supply. Consider the number of I/O modules you plan to connect to confirm the POINTBus current is sufficient.
