This model is no longer manufactured!

You can reaplace it with NetControl 2RU2S1A1P.


This model is specially developed for ISP (Internet Service Provider) aiming to cover the most typical needs for control and monitoring in city LANs. It is extremely convеnient for integration inside local telecommunication racks/cabinets in systems with centralized powering trough the free pairs in UTP/FTP cables (simple PoE), especially due to integrated power converter module allowing device to be directly powered from the centralized power. The integrated power converter delivers 12VDC for internal operation of device while allowing customer to use this voltage for powering external devices (12VDC voltage is available on the screw terminals panel).
