The Allen-Bradley 1734-AENT, also cataloged as the 1734-AENT Ethernet Adapter Module, operates as a dedicated hardware component for network interface execution within Allen-Bradley Point I/O 1734 platforms.
The 1734-AENT network interface module links backplane expansion racks directly to EtherNet/IP deterministic networks, sustaining 10/100 Mbits/s throughput across half and full-duplex operation. Designed to manage backplane bus communication velocity across local Point I/O modules, the adapter coordinates continuous I/O packet scanning and diagnostic transfers. High-density I/O expansion is supported via an integrated field power bus supplying up to 10 A of continuous current, while maintaining 1800 VDC isolation integrity between control networks and local power circuits.
Frequently Asked Questions
Q: What is the maximum current capacity supported on the 1734-AENT field power bus?
A: The internal field power bus supports a maximum supply current of 10 A across an operating range of 10 to 28.8 VDC.
Q: What level of electrical isolation does the 1734-AENT adapter provide?
A: The module isolation design is factory tested to withstand 1800 VDC for 60 seconds between network circuits and field power lines.
Field Installation Guidelines
Mount the 1734-AENT adapter onto the DIN rail first to serve as the primary network interface head for the Point I/O assembly.
Connect the main 24 VDC control power supply to the adapter terminals, ensuring inrush current capacity supports up to 6 A for 10 ms during initial startup.
Plug standard RJ45 Ethernet cabling into the front port, verifying network switches support 10/100 Mbits/s auto-negotiation in full or half-duplex configuration.
Ensure power distribution wiring to the field bus stays strictly within 10 to 28.8 VDC to maintain system isolation and prevent thermal overload.
