Description

Brief Product Description

The Allen-Bradley 1783-ETAP is a high-performance, three-port EtherNet/IP tap designed to integrate non-DLR devices into linear or ring network topologies. This compact module facilitates high-speed 100 Mbps data transmission while providing hardware redundancy and simplified cable management for industrial automation systems.

Advanced Device Level Ring (DLR) Integration

The Allen-Bradley 1783-ETAP serves as a critical networking interface that enables standard Ethernet devices to participate in advanced industrial topologies. By utilizing embedded switch technology, this module allows users to connect single-port devices—such as older PLCs, drives, or HMI panels—directly into a high-availability Device Level Ring (DLR) or linear network. This capability eliminates the requirement for expensive external managed switches at every drop point. Furthermore, the 1783-ETAP supports the ring supervisor function, which actively monitors the network integrity and automatically reroutes data traffic in the event of a cable break, ensuring near-zero recovery time and maximum system uptime.

Efficient Power Management and Compact Design

Rockwell Automation engineered the 1783-ETAP with a focus on energy efficiency and space optimization. The module operates on a standard 24V DC nominal power supply (ranging from 20.4 to 27.6V DC) and consumes a remarkably low 4.8 watts during full operation. This low thermal footprint allows for high-density installation in compact control cabinets where airflow might be limited. Additionally, the device features three 10/100 Mbps copper ports with RJ45 connectors, providing a familiar and robust physical interface for industrial technicians. Its rugged construction ensures that the internal electronics remain protected against the vibrations and electrical noise typically found on factory floors.

Flexible Network Architecture and Simplified Deployment

The 1783-ETAP provides immense flexibility for system integrators tasked with expanding existing automation networks. Because the module facilitates daisy-chaining, it significantly reduces the amount of total cabling required for a project, lowering both material costs and installation labor. The device integrates seamlessly with the Studio 5000 environment, allowing for rapid configuration of IP addresses and network parameters through standard software tools. Whether deployed in high-speed packaging lines, complex conveyor systems, or distributed material handling applications, the 1783-ETAP delivers a reliable and cost-effective solution for modernizing industrial communication infrastructure.
