CTC UNION 4 Port Gigabit Managed PoE Switch. -10C ~60C.

Model: IGS-402SM-4PH24

CTC UNION 4 Port Gigabit Managed PoE Switch. -10C ~60C. 4x 10/100/1000Base-T(X), plus 2x100 /1000Base-X SFP.PoE+ power budget 120W. Power consumption V DC/W: 24/135.2, 48/132.5. Din-kit incl.

This series models are managed industrial grade gigabit PoE (Power over Ethernet) switches with 4/8/16 10/100/1000Base-T PoE ports and 2/3/8 Gigabit/Fast SFP ports that provide stable and reliable Ethernet transmission. With dual power input design, the series models can provide redundant mechanisms for critical applications that need always-on connections. These switches can also operate either at a standard operating temperature range (-10°C  to 60°C) or at a wide operating temperature range (-40°C  to 75°C) so as to fulfil the special needs of industrial automation applications.
