Configured for DeviceNet communication between POINT I/O modules and controller networks, the Allen-Bradley 1734-ADN (1734-ADN DeviceNet Network Adaptor) provides direct physical network interface execution.

Model Identification

The 1734-ADN is a POINT I/O communication adaptor designed for DeviceNet networks. The module provides the interface between distributed POINT I/O terminal modules and the DeviceNet fieldbus infrastructure. The device supports modular I/O expansion with a DeviceNet communication rate range from 125 Kbit/s to 500 Kbit/s.

Hardware Specifications

EtherNet/IP and Industrial Network Integration

The POINT I/O platform uses modular communication adaptors to connect remote I/O assemblies with industrial controller networks. The 1734-ADN performs DeviceNet protocol communication, managing data exchange between field-connected I/O modules and the network master.

The module supports I/O density scaling by allowing multiple POINT I/O modules to be installed on a common backplane assembly. DeviceNet communication parameters are determined by the selected network baud rate and controller configuration.

Ordering Information

The shipment configuration includes:

• 1 x Allen-Bradley 1734-ADN POINT I/O DeviceNet Network Adaptor
• 1 x Standard product housing assembly
• 1 x Terminal connection interface

Additional POINT I/O terminal modules and DeviceNet accessories are installed separately according to system configuration requirements.

Field Installation Guidelines

DIN Rail Mounting

• Install the adaptor on a compatible DIN rail section with proper mechanical locking.
• Confirm module alignment before connecting adjacent POINT I/O modules.
• Maintain sufficient clearance for wiring access and maintenance operations.

DeviceNet Wiring

• Use DeviceNet-compatible cable and follow network topology requirements.
• Separate communication wiring from high-voltage power conductors.
• Connect shield grounding according to the installation design of the control cabinet.

Power Connection

• Verify the 24 VDC supply polarity before energizing the module.
• Check current loading when additional POINT I/O modules are connected.
• Confirm network addressing before controller communication testing.
