Reducing Installation Costs with Distributed I/O
In modern industrial automation, minimizing wiring and cabinet space directly lowers project costs. The Allen-Bradley 1734-ADN POINT I/O DeviceNet communication module enables distributed I/O architectures that reduce expensive point-to-point cabling. By placing I/O modules closer to sensors and actuators, engineers save on material and labor while improving signal integrity.
Introducing the 1734-ADN DeviceNet Adapter
Petro Auto Tech now offers the Allen-Bradley 1734-ADN, a DeviceNet adapter module from the POINT I/O series. This module acts as the communication interface between a DeviceNet master controller and up to 63 POINT I/O modules on the local bus. It requires 23 Volts DC input voltage and draws 400 milliamps from the field side, with an inrush current of 6 amps. The adapter consumes 8.1 Watts of power and dissipates 2.8 Watts at 28.8 Volts, making it energy-efficient for continuous operation.
Technical Specifications That Drive Value
The 1734-ADN supports a maximum of 504 I/O points across 63 powered modules, allowing scalable system design. Its DeviceNet communication rate can be set to 125K, 250K, or 500K bits/second, matching network speed requirements without overprovisioning. The POINTBus current of 1000 milliamps ensures reliable backplane power distribution. These specs translate to lower per-point costs and reduced energy waste compared to traditional centralized I/O.
Real-World Applications and Cost Savings
In a packaging line, the 1734-ADN connects remote sensors and actuators to a central PLC via DeviceNet, eliminating long cable runs. A material handling system benefits from the module's ability to support 63 I/O modules, reducing the need for multiple adapters. For a water treatment plant, the 1734-ADN's low power consumption of 8.1 Watts minimizes operational electricity costs over the system's lifetime.
Customer Case Scenario: Upgrading a Legacy System
Consider a factory with an aging DeviceNet network using separate communication modules for each I/O rack. By replacing them with a single 1734-ADN adapter and POINT I/O modules, the facility reduces hardware costs by 30% and cuts installation time by half. This illustration shows how the 1734-ADN delivers immediate ROI through simplified wiring and reduced component count.
Compatibility and Integration
The 1734-ADN integrates seamlessly with any DeviceNet master controller and supports Auto Device Replace (ADR) for quick module swaps. It mounts on a DIN rail and must be installed on the left side of a 1734 system. The module's autobaud feature detects network baud rates from 125K to 500K bits/second, ensuring plug-and-play compatibility without manual configuration.
