The Atop EHG2316C series includes 16-port industrial Gigabit Ethernet switches in non-PoE and PoE/PoE+ versions. The EHG2316C-16PoE complies with IEEE 802.3af and IEEE 802.3at. It delivers up to 15W per port for PoE or 30W per port for PoE+, subject to a 240W total PoE budget.

Four DIP switches provide LLDP packet forwarding/blocking, Strict QoS/non-QoS selection, port isolation, and Broadcast Storm Control.

Designed for rugged industrial environments, the EHG2316C series features:

• Model-specific input: 12-58VDC (non-PoE); 48-57VDC (PoE); 51-57VDC (PoE+)
• Required source rating: 1A min (non-PoE); 6A min (PoE); 5A min (PoE+)
• Dual power inputs with reverse-polarity and over-current protection
• IP40 fanless housing; DIN-rail installation and optional wall mounting
• -40°C to 70°C operation; IEC/EN/UL 62368-1, CE and FCC Class A compliance.

The series is suited to industrial automation, transportation, energy, surveillance, and other harsh-environment networks.
