Product Introduction
The Allen-Bradley 1734-ADN is a DeviceNet Adapter Module from the POINT I/O series. It enables distributed I/O by connecting POINT I/O modules to a DeviceNet network. This module uses 23 Volts DC input voltage and draws 400 milliamps field side power with a 6 Amp inrush current. It mounts on a DIN rail and serves as the leftmost adapter in a 1734 system.

These specifications ensure reliable operation in industrial environments. The 1734-ADN supports up to 63 I/O modules and 504 I/O points, making it suitable for large distributed systems.
Industry Applications
The Allen-Bradley 1734-ADN is ideal for upgrading existing DeviceNet installations. It replaces older adapters with a compact DIN-rail design. Use it in manufacturing lines, packaging machinery, and material handling systems where distributed control is required. For example, a factory with multiple POINT I/O racks can consolidate communication using this single adapter.
Installation & Setup Guidance
Install the 1734-ADN vertically on a DIN rail. Push firmly until the locking mechanism engages. Connect the DeviceNet plug and tighten the holding screws. Set the node address using the thumbwheel switch (addresses 0 to 63). The autobaud feature detects network baud rate automatically, supporting 125K, 250K, or 500K bits/second. The module performs a self-test on power-up and uses non-volatile memory for default settings.
Selection Guide & Purchasing Advice
Before purchasing, verify that your system uses DeviceNet communication. The 1734-ADN requires 23VDC power and fits POINT I/O racks. Ensure you have compatible base units and terminators. For reliable supply, consider UBEST Automation as your source for genuine Allen-Bradley parts.
