PT-PIS4PB1S-AC is an AC to DC industrial-rated 4-port PoE switch that has one SFP uplink offers a unique solution to powering long-range installations, where the data input comes over fiber, such as special scenarios, like highway side, exurb applications.  Enclosed in an IP40 high-impact metal case but can work outdoor by being covered with a waterproof case. All the Ethernet copper ports have 4KV surge protection.

It works with a wide input voltage of 100-240Vac and operates from -40℃ to 75℃. This model includes 1 SFP fiber slot at 1000BASE-X, 1 power input terminal block and 4 PoE ports, providing 90W each port power for remote PDs over 4 pairs output at 10/100/1000Mbps of data speed. Each PoE port is compliant with BT standard and backward compatible with 802.3af/at. Such as power for Pan Tilt Zoom cameras/IP cameras, VoIP video phones, building/access control equipment, WiFi access devices, POS terminals, thin clients, kiosks, and IP print servers. 

It can also be fed by 48-55Vdc. That is two power AC and DC inputs of the terminal block, you can choose either one to go ahead. Do not connect both AC and DC power simultaneously, otherwise, there will be a risk of damage to the unit. 

For planning purposes, the effective distance is 100 meters over Cat5e/Cat6 cables. This model is equipped with a standard DIN rail mounting bracket, which can easily jam into the guide rail.
