VOLKTEK SEN-9425P-24V-RW 4 Ports GbE Railway Certified Unmanaged PoE+ Switch with 1 RJ45 and 2 SFP Ports SEN-9425P-24V-RW is a 4-port 10/100/1000 PoE+ downlink, 1-port 10/100/1000 RJ45 downlink, and 2-port GbE SFP uplink unmanaged industrial-grade switch designed to meet the thermal requirements and environmental conditions of surveillance and WAP Railway applications. This PoE+ switch features up to 4-port PSE (power sourcing equipment) ports with plug and play features to provide power to all the powered devices (PDs) as soon as they are connected. The fiber ports allow noise-free Gigabit Ethernet transmission for fast recovery, reliable and long-distance to other switches or the control center. To keep a stable transmission of video and data the device uses rate limitation and QoS (Quality of Service) and prioritizes industrial applications using protocols like EIP, PROFINET, and GOOSE.
This switch is built with industrial-grade components, enclosed in an IP30 aluminum case with high thermal conductivity to protect the device from tools and hazards. The wide input power range from 24V to 57V enables the device to operate in many substation applications without extra power outlet installation needed. The device has two power input methods, a 2-pin Terminal Block and a 4 pin mini-DIN that attaches firmly to the device avoiding it from disconnecting during strong vibrations. Designed to withstand vibration, shock, free fall, and temperatures ranging from -40℃~75℃ (-40°F~167°F) it suits heavy industrial environments.
