Description

Product Overview

The Allen-Bradley 1734-ADN is a POINT I/O DeviceNet communication adapter module manufactured by Rockwell Automation. Designed for distributed I/O architectures, this compact module mounts on the leftmost position of a POINT I/O assembly, interfacing up to 63 local POINT I/O modules with a primary DeviceNet control network.

Operating on a 24 V DC nominal power supply with a 1000 mA POINTBus backplane current output, the 1734-ADN supports communication rates of 125K, 250K, and 500K bits/second with autobaud detection capability. Weighing 0.22 kg (0.49 lbs) with an estimated package shipping weight of 0.45 kg (0.99 lbs), this DIN rail-mounted adapter features built-in rotary node address switches (0–63) and Auto Device Replacement (ADR) functionality.

Core Technical Advantages

  • High Module Expansion Capacity: Drives up to 63 POINT I/O modules and up to 504 I/O points on a single backplane rack layout.
  • Auto Device Replacement (ADR): Simplifies maintenance by automatically downloading saved configuration parameters to replacement modules on power-up.
  • Flexible Communication Rates: Supports standard DeviceNet rates (125K, 250K, 500K baud) with automatic baud rate matching up to 1 Mbaud.
  • Compact DIN Rail Mounting: Features a quick snap-locking mechanism that mounts directly on standard EN 50022 DIN rails for rapid, vertical system assembly.
