4-P Gigabit + 1-TP/SFP(100/1G) combo + 1-SFP(100/1G) slot Industrial Switch,
with External DC power DIN


  • RP-ISG421A is a 4-P Gigabit + 1-TP/SFP combo + 1-SFP(100/1G) slot Industrial Switch.RP-ISG421A  is designed for supporting standard industrial applications without complex setup to make the network truly plug-and-play. RP-ISG421A can be used to connect several Ethernet devices like Ethernet I/O, IP-Camera or other Ethernet switches. In addition, RP-ISG421A provides wild power input voltage range +12 ~ + 56Vdc for application flexibility which secures equipment against unregulated voltage and makes systems safer and more reliable. RP-ISG421A accepts 3 power input sources: PW1, PW2, and Power DIN (or external power adapter.  .

    With the 5 10/100/1000Mbps Gigabit Ethernet ports, RP-ISG421A provides non-blocking switch fabric and wire-speed throughput as high as 10Gbps, RP-ISG421A performs wire-speed packets transfer without risk of packet loss.

    The protection of compact IP-30 standard metal case allows for either DIN rail or wall mounting for efficient use of cabinet space.
