The ThinkEdge SE3 IOBOX connects to ThinkEdge SE3 via a Type-C connection, providing extra vertical IO offerings such as Power over Ethernet (PoE), Digital Input/Output, and a Serial port (RS232/422/485) offering flexibility and adaptability during Retail, Manufacturing, and Smart Building system integration. One DC cable provides voltage input to the IOBOX and PC device simultaneously, saving customers the extra burden of an AC/DC power transfer in industrial DC power supply environments.
