CIS-300 series are designed for industrial-grade Ethernet, and particularly for facilities of rugged industry and infrastructure. CIS-300 series are tailored to perform various features, such as wide temperature, relay output alarm, surge protection...etc. Thus, CIS-300 series is the best choice for facility management, sewage treatment, power utility, telecommunication, transportation and all other mission-critical applications that require reliable Ethernet connectivity.

Redundant Power Input
CIS-300 series offer three different power inputs to enhance its reliability, two supplied by terminal block, and one by power jack. When the primary DC power input fails, the backup power input will take over immediately to guarantee a non-stop operation.

Relay Output Alarm by Power Failure
CIS-300 series provide technicians with relay contact outputs for a warning while the power fails. It makes them to quickly respond appropriate procedure, and handle any emergent situation.

High ESD Protection
CIS-300 series feature on electrical surge  protection. This unique design perform high ESD protection which meets EN61000-4-2 standard and the surge protection which meets EN61000-4-5 standard. This remarkable feature guarantees you the best quality of communication under various critical conditions.
