Allen-Bradley 1734-ACNR Brand Introduction Allen-Bradley 1734-ACNR is POINT I/O series ControlNet network adapter developed by Rockwell Automation for distributed I/O fieldbus networking. It specializes in data exchange between ControlNet controllers and POINT I/O modules, supporting redundant coaxial media connection for industrial control network. Communication Adapter is the core unit of Allen-Bradley 1734-ACNR. Communication Adapter adopts DIN rail mounting structure for cabinet installation. Communication Adapter supports up to 63 POINT I/O modules connection. Communication Adapter realizes real-time I/O data transmission and network node management. Allen-Bradley 1734-ACNR provides stable Bus for workshop distributed automation control. Bus has dual coaxial ControlNet ports for redundant network. Bus integrates LED status indicators and node address thumbwheel switch. Bus supports network access port for on-site network diagnosis. Allen-Bradley 1734-ACNR features reliable Transmission for PLC and remote I/O interaction. Transmission follows ControlNet fieldbus protocol. Transmission works with 24VDC power supply and supplies 5V backplane current for POINT I/O base. Transmission supports high-speed time-critical signal exchange between controller and field I/O. Allen-Bradley 1734-ACNR is widely used in assembly lines, material handling equipment and legacy Rockwell ControlNet system renovation. With mature Rockwell POINT I/O bus technology, this adapter works within temperature range 0~60℃ and has strong anti-vibration and anti-interference performance. It provides full lifecycle technical support including wiring, commissioning and after-sales maintenance, serving global users as a trusted ControlNet network adapter solution.
