Antaira LMP-0800G-24 8-Port Gigabit Managed DIN Rail Ethernet Switch with 8x PoE+ (240W) and 12-55V DC Input

Mobile PoE applications and other low-voltage sources, as Antaira describes them, often offer only 12 V or 24 V DC. The LMP-0800G-24 is the standard temperature build in the Antaira LMP-0800G-24 series: a gigabit managed industrial switch with eight PoE+ ports and a built-in voltage booster for 12 V to 55 V DC input.

It has eight 10/100/1000Base-TX RJ45 ports, all IEEE 802.3af/at PoE+ at up to 30 W per port, on a 16 Gbps store-and-forward fabric with an 8K MAC table. It is a Layer 2 managed switch with IEEE 802.1Q VLANs, IEEE 802.1p QoS, IGMP v1/v2 multicast filtering, LACP, SNMP v1/v2c/v3, RMON and DHCP Option 66/67/82. ITU-T G.8032 ERPS restores a broken ring in under 50 ms, alongside STP, RSTP and MSTP, and Modbus TCP supports SCADA monitoring. Set-up is by web console, Telnet or CLI, with IEEE 802.1X, HTTPS and SSH/SSL for secure access. A PoE Ping Alarm can power-cycle unresponsive PoE devices, and a USB 2.0 port backs up the configuration.

Power arrives on 12 V to 55 V DC redundant inputs on a removable 6-pin terminal block, so either supply can carry the load. A voltage booster gives full 48 V DC PoE, and the budget depends on input voltage: 90 W at 12 V, 180 W at 24 V and 240 W from 48 V. Overload current, reverse polarity, EFT and ESD protection are built in, along with a CPU watchdog, and exceptions can trigger an e-mail or relay alert.

The LMP-0800G-24 is rated -10 °C to 70 °C, for heated cabinets and indoor plant. It has an IP30 metal housing for DIN-rail or optional wall mounting, designed to IEC 60068-2-27 shock and IEC 60068-2-6 vibration. Antaira lists FCC, CE and UL 61010-1 certifications with RoHS compliance, and the switch carries Antaira’s 5-year warranty. The LMP-0800G-24-T extends the range to -40 °C to 75 °C, and the LMP-0800G is the 48 V to 55 V DC version of the same switch. We supply the LMP-0800G-24 and can pre-configure IP addressing, VLANs and ring settings.
