Description
5 Port Unmanaged Ethernet Switches with 4 IEEE 802.3bt PoE++ Ports
The HES5A-4E60 series are smart, 5-port, unmanaged Ethernet switches supporting 4 PoE++ ports, with each port can provide up to 60 watts of DC power. The switches can be used for the indicators, LEDs, cameras and media screens in railway or other industrial Internet ap?plications. Compliant with IEEE802.3bt and the optional power class feature, HES5A-4E-60 allows the PD to indicate its power requirements at different voltages. The compact design makes HES5A-4E60 suitable for limited installing space. The switches can be easily installed on a DIN-rail or multi-directional panel mounting, and wide temperature models are optional. The minimum 9VDC power input is designed for the emergency circumstances that the train starts its standby battery which is 9VDC output.
