Moxa EDS-316-MM-ST-T , 14 10/100BaseT(X) ports content_copy

The EDS-316-MM-ST-T is an industrial unmanaged Ethernet switch from the brand Moxa, designed for use in demanding environments with high requirements for reliability and operational safety. The device features 14 copper ports (RJ45) with 10/100BaseT(X) and two fiber optic ports (100BaseFX, SC, Single-Mode), enabling a range of up to 80 km. This combination makes the switch particularly suitable for connecting over long distances, for example in infrastructure applications such as railway infrastructure, power supply, or pipeline systems, where a stable, long-distance network connection is required.

Applications

The switch is designed for use in industrial environments where high mechanical and thermal stress resistance as well as a secure network connection are necessary. Certifications according to ATEX Zone 2 and Class I Div. 2 allow use in potentially explosive areas, where the devices meet the requirements for safety and functionality in such environments. Mounting is flexible on DIN rail or in an enclosure, facilitating integration into existing industrial control and monitoring systems.

Functions and Equipment in Detail

The switch supports automatic port negotiation (Auto-Negotiation), half- and full-duplex mode, as well as Auto MDI/MDI-X, enabling a compatible connection to various network devices without manual settings. An integrated relay output with a specification of 1 A @ 24 VDC serves to signal power failures or port interruptions, enabling a quick response to network disturbances. The Broadcast Storm Protection ensures that the network remains stable even under high data load by limiting uncontrolled broadcast transmissions.

Technology Explained Simply

The two fiber optic ports (Single-Mode, SC connector) enable data transmission over fiber optic cables with a range of up to 80 km, which is particularly advantageous for connecting remote sites in industrial networks. The copper ports (RJ45) provide a standard connection for local devices and are designed for 10/100 Mbit/s. The -T version of the device features an extended operating temperature range of -40 to 75 °C, enabling use in extreme climatic conditions, such as in arctic or desert regions. The devices undergo a 100 % Burn-In test to ensure reliability under realistic operating conditions.

Compatibility and Accessories

The switch is compatible with standard network devices using RJ45 connectors or single-mode fiber optic cables with SC connectors. As an alternative, the model EDS-316 is offered, which is also unmanaged but features exclusively 16 copper ports (10/100BaseT(X)) without fiber optic ports.

Mounting and Installation

Mounting is either on a DIN rail or in an enclosure, with no additional mounting accessories required. Installation is performed by connecting the network cables to the RJ45 or fiber optic ports, where automatic functions such as Auto-Negotiation and Auto MDI/MDI-X enable easy commissioning.

Advantages in Operation

Operation of the switch is characterized by high stability and reliability. The integrated alarm function via the relay output enables quick fault detection, while the Broadcast Storm Protection safeguards network integrity during peak loads. Certifications according to FCC, UL, CE, ATEX Zone 2, and Class I Div. 2 guarantee compliance with international safety and performance standards. The -T version offers additional robustness through the extended temperature range, expanding the range of applications in critical environments. The devices are designed for continuous operation and are suitable for applications where network downtime is not tolerable.
