Description
LMP-1204G-SFP series – High-performance 12-port Gigabit PoE+ managed Ethernet switches for demanding industrial environments
The LMP-1204G-SFP series offers reliable and flexible network solutions with 8x 10/100/1000Tx Ethernet ports that support IEEE802.3at/af PoE+ for up to 30 W per port. Connectivity is complemented by 4x 100/1000Fx SFP fiber ports that can accommodate both single and multi-mode modules, opening up a wide range of possible applications.
Advanced management and high network security
These fully manageable Layer 2 switches feature an intuitive web management interface and support ring network redundancy based on the ITU-T G.8032 ERPS protocol. With a network recovery time of less than 50 ms, they are ideal for critical applications. Additional functions such as IGMP, VLAN, QoS, SNMP, RMON, Modbus TCP and 802.1X / HTTPS / SSH / SSL offer comprehensive security and optimization options for industrial networks.
Robust and reliable in any environment
The LMP-1204G-SFP series is equipped with a metal housing that complies with protection class IP30. Thanks to the DIN rail mounting option, the switches are easy to install. Two model variants are available for use in different conditions: one for standard temperatures from -10 °C to 70 °C and one for extended temperatures from -40 °C to 75 °C. High EFT and ESD protection ensures reliable operation in demanding environments.
