Ethernet Switches Work in DC
Adam Ethernet switches accept any voltage 10-30 VDC and have surge protection to 3,000 VDC. Model 5521 connects four copper and one fiberoptic networks, while model 6520 has five RJ45 Ethernet ports. Both automatically sense 10 or 100 Mbps speeds, and provide full or half-duplex control. They mount on DIB rails, walls, and piggyback, and have diagnostic LEDs on the front panel for power and networking status.
