Moxa EDS-316-MM-SC-T , 14 10/100BaseT(X) ports, -40 to 75 °C content_copy

The Moxa EDS-316-MM-SC-T is an unmanaged Ethernet switch designed for use in industrial networks. It features 14 ports with 10/100BaseT(X) copper connections and two fiber optic ports with 100BaseFX technology in multi-mode format, connected via SC connectors. The device is designed for operation in extreme environments and supports an extended temperature range of -40 to 75 °C, making it particularly suitable for applications in harsh industrial environments. Mounting is either on a DIN rail or in an enclosure, enabling flexible integration into existing infrastructures.

Applications

The switch is intended for production environments, automation networks, and infrastructure projects where a reliable, low-maintenance network connection is required. Certification for use in hazardous areas (ATEX Zone 2, Class I Div. 2) extends its application range in sensitive installations, for example in petrochemical or mining industries. The 100%-burn-in test, to which all devices are subjected, ensures high operational reliability and minimizes failure risks.

Functions and Equipment in Detail

The switch operates completely passively, without management functions, simplifying installation and maintenance. It features an integrated relay output that triggers an alarm in case of power failure or port disconnection. The relay output specification is 1 A at 24 VDC. Additionally, a Broadcast Storm Protection function safeguards the network against data flooding caused by uncontrolled broadcast or multicast traffic. The Auto MDI/MDI-X function enables automatic connection adaptation regardless of cable type, and half-/full-duplex as well as automatic speed negotiation ensure optimal adaptation to connected devices.

Technology Explained Simply

The 14 copper ports support data rates of 10 or 100 Mbit/s and are designed for standard network cables (Cat5e or higher). The two fiber optic ports enable connection via optical cables in multi-mode format, with the SC connector ensuring a secure and robust connection. The fiber optic connections are suitable for use in environments with high electromagnetic interference, as they do not transmit electrical signals. The operating temperature range of -40 to 75 °C makes the switch suitable for outdoor use or in machine rooms with significant temperature fluctuations. Certifications FCC, UL, and CE confirm compliance with applicable electromagnetic compatibility and safety standards.

Compatibility and Accessories

The switch is compatible with other models in the EDS-316 series, particularly variants that also support multi-mode fiber optic connections. The model designation EDS-316-MM-SC-T indicates the combination of multi-mode fiber (MM) and SC connector. Alternatives include models with single-mode fiber or a mix of single- and multi-mode connections, which can be selected based on network architecture. The unmanaged architecture requires no additional configuration or network management software, simplifying integration into existing systems.

Mounting and Installation

Mounting is either on a DIN rail or in an enclosure, allowing flexible placement in various industrial environments. Installation requires no special tools, as connections are made directly via RJ45 and SC connectors. The passive nature of the device means no network management software or configuration is required — devices are ready for use immediately after physical cabling.

Operational Advantages

Operation of the switch is low-maintenance and reliable, as no management functions are required. The integrated alarm function via relay output enables quick response to disruptions. The high operating temperature and certification for hazardous areas extend the application range in demanding environments. The combination of copper and fiber optic connections offers flexibility in network design, with fiber optic connections being suitable for longer distances or interference-prone environments.
