SEN-9425-24V-SS is a 4-port 10/100/1000 PoE+ downlink, 1-port 10/100/1000 RJ45 uplink, and 2-port GbE SFP uplink unmanaged industrial grade switch designed to work in Substation environments. 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.

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.


Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.

Innovative Power Boost Technology
24V to 57V DC power boosting with DC-to-DC converter for high-power requiring PoE/PoE+ devices.

High-Power Budget for PoE Devices
Up to 30W per port (IEEE 802.3af/at) powering to PoE+ devices.

DIN-Rail mountable Power Adapter (AC to DC) 
DIN-Rail mountable power adaptor with 4-pin mini-DIN power connector.
