Moxa EDS-408A-3M-SC-T , 5x 10/100BaseT(X) ports, -40 to 75 °C content_copy

The EDS-408A-3M-SC-T from Moxa is an industrial 8-port managed Ethernet switch designed for use in automation systems, power supply, and infrastructure environments. The device features a robust metal housing construction with IP30 protection rating, providing dust and shock protection, and is designed for operation in a temperature range of -40 to 75 °C, making it suitable for demanding industrial environments. Mounting is standard on DIN rail, with optional wall mounting available. The devices are designed for high network availability and support Turbo Ring and Turbo Chain with a recovery time of less than 20 milliseconds for up to 250 switches, complemented by RSTP and STP for redundant network topologies.

Applications
This switch is specifically designed for industrial applications requiring reliable and interference-resistant network connections. It is suitable for use in manufacturing automation, power supply, rail transport, and other critical infrastructures. Certifications including EN 50121-4 for rail, ATEX/IECEx for explosive environments, and marine approvals from DNV, NK, LR, and ABS highlight its suitability for demanding environments. The MTBF (mean time between failures) is up to over 1.3 million hours depending on the model, indicating high reliability.

Functions and Features in Detail
The EDS-408A-3M-SC-T provides five 10/100BaseT(X) copper Ethernet ports and three 100BaseFX fiber optic ports with SC connector in multi-mode format. The fiber ports enable flexible connections over longer distances, with the SC connector ensuring a secure and standardized optical connection. The switches support VLANs according to IEEE 802.1Q, port-based VLANs, GVRP, IGMP Snooping, and Quality of Service (QoS) to prioritize critical data streams. This is particularly important in real-time systems where latency must be minimized.

Technology Explained Simply
The support for Turbo Ring and Turbo Chain enables rapid network recovery after a failure, with recovery time under 20 milliseconds. This is crucial to avoid production downtime. The RSTP and STP functions ensure redundant paths in the network, preventing loops and enhancing network security. The QoS function allows prioritization of data traffic, ensuring time-critical control or sensor data is processed before other data streams. Integrated SNMPv1/v2c/v3 support enables centralized network monitoring, while Port Mirroring and bandwidth control facilitate network analysis and management.

Compatibility and Accessories
The switches are manageable via a web interface, CLI, Telnet, serial console, a Windows utility, and the configuration module ABC-01. Graphical network analysis is supported by MXstudio. Models from the EIP and PN series support EtherNet/IP or PROFINET directly from the factory, enabling seamless integration into existing industrial control systems. The devices are equipped with RJ45 protective caps to protect connectors from dust and contamination.

Mounting and Installation
Mounting is standard on DIN rail, with optional wall mounting available. The robust metal housing construction ensures safe operation in industrial environments. The devices are designed for operation in a temperature range of -40 to 75 °C, enabling broad applicability across various climatic conditions.

Operational Advantages
The EDS-408A-3M-SC-T offers high network availability, easy management via multiple interfaces, and flexible port configuration with copper and fiber optic connections. Support for industrial protocols such as EtherNet/IP and PROFINET, along with certifications for explosive environments and rail transport, makes this switch a reliable solution for critical applications. The long MTBF and robust construction ensure low-maintenance operation over an extended period.

Scope of Delivery
The scope of delivery includes: 1x EDS-408A switch (model-dependent), 1x RJ45-to-DB9 console cable, 4x RJ45 protective caps.
