Moxa EDS-516A-MM-SC Managed Ethernet Switch Series

Product Introduction

Engineered for robust industrial networking, the Moxa EDS-516A-MM-SC belongs to the advanced EDS-516A Series managed industrial Ethernet switch lineup. This high-performance device delivers dependable data transmission across harsh operational environments, combining fourteen 10/100BaseT(X) ports with two multi-mode SC optical fiber ports.

Industrial automation engineers rely on this managed switch to maintain resilient ring topologies, secure VLAN configurations, and precise packet prioritization. Its IP30-rated metal housing, dual redundant power inputs, and wide operating temperature range ensure continuous uptime in factory automation, substation control, and intelligent transportation systems.

Global PLC Spare HUB Review: Integrating the EDS-516A-MM-SC into legacy plant networks minimizes packet loss during heavy traffic surges. Field commissioning engineers frequently pair this switch with distributed control systems to isolate broadcast storms without disrupting critical Modbus TCP polling loops.

Frequently Asked Questions

What recovery time does the Turbo Ring protocol achieve on the EDS-516A-MM-SC?

The embedded Turbo Ring and Turbo Ring v2 protocols achieve fault recovery times of under 20 milliseconds with a network capacity of up to 250 switches.

Can this switch handle heavy electrical noise in substations?

Yes. The unit meets rigorous industrial EMC standards, including IEC 61000-4 surge, EFT, and ESD protection, making it ideal for high-interference electrical environments.

How do I reset the device to factory default settings?

You can restore factory defaults by accessing the web-based management interface, utilizing the command-line utility via the serial console, or toggling designated configuration scripts.

What is the recommended approach for selecting multi-mode fiber patch cables?

Global PLC Spare HUB's Insight: Always match the modal bandwidth of your optical patch cords to the 100BaseFX multi-mode SC ports. For runs exceeding 2 kilometers, verify optical power budgets to prevent receiver saturation.
