- Wide Temperature Range: -10 to 60°C continuous operation without forced cooling
- High MTBF: 1.32 million hours — minimizes unplanned downtime in 24/7 production environments
- Industrial EMC Compliance: Hardened against electrical noise from VFDs, servo drives, and high-current switching
- Auto MDI/MDI-X: Eliminates crossover cable errors during field installation
System Architecture & Signal Flow
The EDS-208A operates as a Layer 2 store-and-forward switch. Incoming Ethernet frames are buffered, error-checked (CRC), and forwarded to the destination port based on the 1K MAC address table. Auto-negotiation on all 8 RJ45 ports allows mixed 10/100 Mbps device connections without manual speed configuration. The dual-input power architecture accepts two independent DC sources; if the primary source fails, the secondary takes over instantly with a fault relay signal output to the supervisory system. The IP30-rated steel enclosure and DIN-Rail clip allow direct mounting inside IEC 60439-compliant control panels.

Technical FAQ
Q: Does the EDS-208A support VLANs or QoS?
A: No. As an unmanaged switch, it does not support VLANs, QoS, or SNMP. For managed features, consider the Moxa EDS-308 or EDS-510A series.
Q: Can it operate at -40°C?
A: The standard EDS-208A is rated to -10°C. For -40°C operation, specify the EDS-208A-T wide-temperature variant.
Q: What is the maximum cable length per port?
A: 100 m (328 ft) per IEEE 802.3 standard using Cat5e or better UTP/STP cable.
Q: Is the EDS-208A compatible with Profinet or EtherNet/IP?
A: Yes. As a transparent Layer 2 switch, it is fully compatible with Profinet, EtherNet/IP, Modbus TCP, and all standard industrial Ethernet protocols.
Q: Does it support fiber uplink?
A: The base EDS-208A is all-copper RJ45. Fiber port variants (SC/ST connectors, single/multi-mode) are available in the EDS-208A-MM-SC and EDS-208A-SS-SC models — contact us for availability.
