The EDS-408A-2M1S-SC from Moxa is an industrial-grade, managed Ethernet switch designed for use in demanding environments such as automation technology, transportation infrastructure, or utility sectors. The device features a robust metal construction and is designed for DIN rail mounting, with optional wall mounting available. The IP30 protection rating ensures protection against solid foreign objects and splashing water, making it suitable for use in enclosed but not fully protected industrial environments. The operating temperature range is -10 to 60 °C, enabling use in standard industrial facilities. Power supply is provided via a voltage of 9.6 to 60 VDC or ±19 to ±60 VDC, depending on the model variant, allowing flexible integration into existing power networks.

Applications

The switch is specifically developed for industrial networks requiring high availability and reliability. It is suitable for applications in manufacturing automation, rail transport, energy supply, and other areas where continuous network connectivity is critical. Support for industrial protocols such as EtherNet/IP, Modbus TCP, and PROFINET IO (on applicable models) enables direct integration into existing control and monitoring systems. Certifications according to UL 508, EN 62368-1, ATEX, IECEx, EN 50121-4, and NEMA TS2 highlight its suitability for safety-critical and specialized application areas, including railway and marine technology.

Functions and Features in Detail

The EDS-408A-2M1S-SC features five 10/100BaseT(X) RJ45 ports, enabling data transfer rates of up to 100 Mbit/s. Additionally, two multi-mode fiber optic ports with SC connectors are integrated, allowing connection via fiber optic cables. The interfaces support Auto-Negotiation, full-duplex and half-duplex operation, as well as Auto MDI/MDI-X, ensuring flexible and automatic adaptation to connected devices. Network functions include Turbo Ring and Turbo Chain with a recovery time of under 20 ms, ensuring high network availability even during disruptions. Additionally, RSTP/STP, IGMP Snooping (v1/v2), VLAN according to IEEE 802.1Q, port-based VLANs, and GVRP are supported to create a structured and secure network environment.

Technology Explained Simply

The integrated redundancy protocols Turbo Ring and Turbo Chain enable rapid restoration of network connectivity after a failure, with a recovery time under 20 ms. This is particularly important in applications where communication interruption could lead to production downtime or safety risks. Support for VLANs (Virtual Local Area Networks) according to IEEE 802.1Q allows logical separation of network segments, enabling traffic isolation and enhanced network security. QoS functions (Quality of Service) according to IEEE 802.1p and TOS/DiffServ ensure that critical data streams such as control or monitoring information are prioritized. Port Mirroring and bandwidth management support network monitoring and optimization.

Compatibility and Accessories

The switch is compatible with a variety of network protocols, including EtherNet/IP, Modbus TCP, and PROFINET IO (on models with PN designation). Management is performed via multiple interfaces: web browser, CLI, Telnet, serial console, Windows Utility, or the ABC-01 module. Support for MXstudio enables visual network analysis. Integrated functions such as DHCP (including Option 82), SNMPv1/v2c/v3, and RMON support network monitoring and management. E-mail and relay notifications enable quick response to network events.

Mounting and Installation

Mounting is standard on a DIN rail, enabling easy integration into existing enclosures. Wall mounting is optionally available. Dimensions are 53.6 mm (height) × 135 mm (width) × 105 mm (depth), allowing the switch to fit into compact enclosures. Weight ranges from 650 to 890 g. Power supply is via an external DC source in the range of 9.6 to 60 VDC or ±19 to ±60 VDC, depending on the model. Installation requires no special tools, as connections are standardized.

Operational Advantages

The EDS-408A-2M1S-SC offers high network availability through integrated redundancy functions, flexible configuration via multiple interfaces, and comprehensive support for industrial protocols. Its robust construction and certifications for specialized applications such as railway and marine technology make it a reliable partner in critical applications. Integrated monitoring functions such as SNMP, RMON, and e-mail notifications simplify network administration and enable proactive fault resolution.

Scope of Delivery

The scope of delivery includes the EDS-408A-2M1S-SC switch, an RJ45-to-DB9 console cable, four RJ45 protective caps, as well as instructions, certificates, and warranty card.
