1734-AENT POINT I/O EtherNet/IP Adapter 1-Port | Allen-Bradley

The Original New Allen-Bradley 1734-AENT POINT I/O EtherNet/IP Adapter is a single-port communication adapter designed to connect POINT I/O modules to Rockwell Automation controllers over standard EtherNet/IP networks. It serves as the network interface for distributed I/O systems, enabling seamless data exchange between up to 63 POINT I/O modules and the master controller.

Core Engineering Highlights:
Single RJ45 Ethernet port | 10/100 Mbps auto-negotiation | Supports up to 63 POINT I/O modules | Star and Tree topologies | 24V DC nominal input | CIP messaging for online parameter access | Series C module compatibility required
