The EDS-316-M-SC is an unmanaged Ethernet switch from the brand Moxa, specifically developed for industrial networking applications. It features 16 ports, including 14 copper ports with RJ45 connectors and 2 fiber optic connections in Single-Mode SC format, enabling a transmission range of up to 80 km. This configuration makes the switch particularly suitable for applications requiring long distances, such as in transportation infrastructure, utility operations, or energy-intensive production facilities. The fiber optic connections utilize the 100BaseFX technology, designed for high data transfer rates and minimal interference from electromagnetic fields.

Applications

The switch is designed for use in demanding environments, particularly in areas with high environmental requirements. The -T version of the device supports an operating temperature range of -40 to 75 °C, making it suitable for outdoor use, climatically extreme regions, or industrial process environments with high heat or cold loads. Certification according to Class I Division 2 and ATEX Zone 2 also allows use in explosive atmospheres, with the devices meeting international safety standards.

Functions and Equipment in Detail

The EDS-316-M-SC offers a range of features that simplify integration into existing networks. These include Auto-Negotiation, automatic adjustment of transmission rate and duplex mode, as well as Auto-MDI/MDI-X, which enables direct connection between switch and end device without additional crossover cables. Support for half- and full-duplex operation ensures flexible use depending on the network environment. The Broadcast Storm Protection safeguards the network against overloads caused by uncontrolled broadcast traffic waves.

Technology Explained Simply

Processing occurs in Store and Forward mode, where entire data packets are received, checked, and then forwarded, ensuring high data integrity. The MAC table with 1,000 entries enables efficient addressing and routing within the network. The buffer size of 512 kbit supports data packet processing under high loads. The integrated relay output function (1 A @ 24 VDC) allows control of external signals, such as during power failure or port interruption, enabling the switch to perform reliable diagnostic functions in safety-critical installations. Port failure detection configuration is done via DIP switches, allowing simple, hardware-based settings.

Compatibility and Accessories

The switch is compatible with standards IEEE 802.3, 802.3u, and 802.3x, ensuring interoperability with a wide range of network devices. As an alternative, the unmanaged EDS-316 with 16 copper ports (10/100BaseT(X)) is available, although it does not offer fiber optic connections.

Mounting and Installation

Mounting is done via DIN rail or in a distribution cabinet, enabling flexible installation in industrial enclosures. The robust metal housing protects the switch from mechanical impacts and supports heat dissipation. The 100 % Burn-In test performed during manufacturing ensures high reliability and minimizes the probability of early failures.

Operational Advantages

The EDS-316-M-SC offers high operational reliability due to its robust construction, wide operating temperature range, and integrated diagnostic function. The combination of copper and fiber optic connections enables a flexible network architecture, where local devices are connected via copper cables and long-distance connections are realized via fiber optics. Certifications according to FCC, UL, and CE ensure compliance with applicable safety and emission standards.
