General
Number of RJ45 ports	14
Relay voltage	24 VDC

The Moxa EDS-316-MM-SC is an unmanaged Industrial Ethernet switch with 14 10/100BaseT(X) RJ45 ports and two 100BaseFX Multi-Mode LWL ports in SC connector format. It is specifically designed for use in industrial environments exposed to high mechanical, thermal, and electrical stresses. The series is characterised by a robust design and high reliability, ensured by a 100% burn-in test before shipment. The devices are designed for use in harsh operating environments, including facilities in manufacturing, power supply, or transportation sectors.

Applications

The EDS-316-MM-SC is suitable for industrial networks requiring a stable, low-maintenance connection. Typical use cases include networking of control systems, sensors, actuators, and other field devices in production plants, factories, or rail transport. The integrated relay alarm function enables rapid response to faults by triggering an alarm relay signal in case of power failure or port interruption. This supports process safety and minimises downtime.

Functions and Equipment in Detail

The switch features an integrated relay alarm function with an alarm relay activated during faults. The relay output specification is 1 A at 24 VDC. The automatic speed negotiation ensures that ports automatically set the optimal transmission rate (10 or 100 Mbit/s). The Auto MDI/MDI-X mode automatically detects cable connections and adjusts pin assignment, enabling direct connections between switches or end devices without crossover cables. Support for half- and full-duplex operation allows flexible adaptation to the network environment.

Technology Explained Simply

The two LWL ports in SC connector format enable fibre cable connection with a transmission rate of 100 Mbit/s in multi-mode format. This interface is suitable for longer distances within industrial facilities, where copper cables are insufficient due to interference or length limitations. The broadcast storm protection function prevents networks from being overloaded by uncontrolled data floods under high data loads, ensuring network stability even under stress. The operating temperature of the standard model ranges from -10 °C to 60 °C, sufficient for use in typical industrial rooms.

Compatibility and Accessories

The EDS-316-MM-SC is part of the EDS-316 series and can be combined with other models in the series to create a comprehensive network. Alternatively, the unmanaged model EDS-316 without LWL ports is available. The LWL ports are compatible with multi-mode fibre cables in SC connector format. Certifications according to FCC, UL, CE, as well as compliance with ATEX Zone 2 and Class I Division 2, make the switch suitable for use in explosive environments.

Mounting and Installation

Mounting is done on a DIN rail or in a distribution box. Installation is simple and requires no special tools. The devices are designed for use in enclosures and can be directly integrated into existing industrial infrastructures.

Operational Advantages

The EDS-316-MM-SC provides a reliable, low-maintenance network connection without complex configuration. The integrated alarm function and broadcast storm protection enhance network security. The certifications enable use in demanding environments, including explosive zones. The robust construction and high operating temperature make the device suitable for use in harsh industrial conditions.
