Antaira's LNP-0500-24 is a 5-port intelligent unmanaged industrial Ethernet switch, compatible with IEEE-802.3at (Power-over-Ethernet Plus) on ports 1 to 4. Redundant Power Input -12 ~ 36VDC. It can also be used as a power supply (PSE) and, when used in this way, the LNP-0500-24 allows centralization of power and supplies up to 30 watts of power per port. The LNP-0500-24 can be used to power IEEE 802.3af or 802.3at compliant power devices (PD), eliminating the need for additional power. Supports IEEE 802.3 / 802.3u / 802.3x with 10 / 100BTx, full / half duplex MDI / MDI-X auto-sensing to provide an economical solution for industrial Ethernet networks. In addition, network storm protection and built-in relay warning function alert network managers when power outages or port interruptions occur.
