The Rockwell module you mentioned, the 1783-EMS08T, is part of the ArmorStratix series of industrial Ethernet switches manufactured by Rockwell Automation. This specific module is an eight-port Ethernet switch module.

Features of the 1783-EMS08T module include:

1. Ethernet Connectivity: The module supports Fast Ethernet (10/100 Mbps) and Gigabit Ethernet (10/100/1000 Mbps) connectivity for seamless communication within an industrial network.

2. Eight Ports: The module has eight Ethernet ports, allowing you to connect multiple devices or network segments to the module.

3. Managed Switch: The 1783-EMS08T is a managed switch, which means it offers advanced features for network management, such as VLANs (Virtual Local Area Networks) for network segmentation and prioritization, QoS (Quality of Service) for traffic prioritization, and security features like authentication and access control.

4. Redundancy: The module supports various redundancy protocols, such as Rapid Spanning Tree Protocol (RSTP) and Device Level Ring (DLR), to ensure network availability and minimize downtime.

5. EtherNet/IP Capable: The 1783-EMS08T module supports the EtherNet/IP protocol, which is widely used in industrial automation applications for communication between devices and controllers.

6. Compact Design: The module is designed to be compact and can be easily integrated into control panels or industrial enclosures.
