Information

Overview Manuals Common Applications Product Precautions

The EDS-405A-SS-SC is a 5-port managed Ethernet switch featuring 3 RJ45 ports and 2 single-mode fiber ports with SC connectors. It provides industrial-grade reliability with IP30-rated metal housing, redundant 12/24/48 VDC power inputs, and robust vibration and shock resistance.

Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), and RSTP/STP for network redundancy
Easy network management by web browser, CLI, Telnet/serial console, Windows utility, and ABC-01
Supports MXstudio for easy, visualized industrial network management

The EDS-405A Series is designed especially for industrial applications. The switches support a variety of useful management functions, such as Turbo Ring, Turbo Chain, ring coupling, IGMP snooping, IEEE 802.1Q VLAN, port-based VLAN, QoS, RMON, bandwidth management, port mirroring, and warning by email or relay. The ready-to-use Turbo Ring can be set up easily using the web-based management interface, or with the DIP switches located on the top panel of the EDS-405A switches.

The EDS-405A-SS-SC supports DHCP Option 82 for dynamic IP address assignment based on different policies, allowing location-based network addressing. To streamline network planning, the switch supports port-based VLAN, IEEE 802.1Q VLAN, and GVRP, segmenting subnets and isolating broadcast domains. Built-in QoS (supporting IEEE 802.1p and TOS/DiffServ) ensures the priority for control commands and real-time industrial data. Additionally, it offers port mirroring for online debugging and packet analysis. Utilizing RMON for network monitoring, SNMPv1/v2c/v3 for multiple levels of network management security, and bandwidth management to prevent unpredictable network status, the EDS-405A-SS-SC protects industrial control networks against abnormal traffic spikes.

Oil & Gas Extraction

Connects remote RTUs to long-distance fiber networks on oil and gas pipelines and offshore drilling platforms to transmit field pressure and flow data back to the central control room.

Petrochemical & Refining

Utilizes single-mode fiber for explosion-proof isolation and anti-electromagnetic interference communication in hazardous refinery tank farms and hydrocracking units to build the network backbone of DCS systems.

Thermal & Nuclear Power Generation

Connects field PLCs, HMIs, and data acquisition boxes under the complex electromagnetic environments of power plant steam turbine and boiler control systems to ensure latency-free transmission of control commands.

Wind Power Generation

Installed at the base or nacelle of wind turbines, leveraging the long-distance transmission of single-mode fiber to connect the operational status of distributed turbines to the substation monitoring center.

Hydropower & Dam Monitoring

Used for long-distance data transmission in dam structural safety, water level monitoring, and hydro-generator control systems, overcoming signal attenuation caused by long cable runs in mountainous or underground environments.

Modern Mining & Extractive Industry

Deployed in underground central substations, conveyor belt lines, or surface mineral processing plants to provide a solid network backbone for automated mining equipment, gas monitoring systems, and explosion-proof video surveillance.

Ensure the power supply voltage remains within the 9.6 to 60 VDC range, and properly connect the dual redundant power inputs and grounding terminal to prevent interference. Since this model features single-mode fiber interfaces, you must use matching single-mode fiber patch cords and keep the SC connectors clean. Never exceed the operating temperature range of -10 to 60°C, and ensure the ring ports are correctly designated when configuring Turbo Ring to avoid network broadcast storms caused by misconfiguration.
