116 BIT GPIO: Industrial computer come with 2 x 18PIN phoenix terminal GPIO interfaces, supporting 16 inputs and 16 outputs 2OPTOCOUPLER ISOLATION FUNCTION: Optocoupler isolation circuit, so that there is no direct electrical connection between the two isolated circuits, preventing interference caused by electrical connections, especially between low voltage control circuits and external high voltage circuits 3SUPPORT 4 WAY POE: 5 x for Intel Gigabit Ethernet ports, support 4 way 802.3af standard POE network ports. POE (Power Over Ethernet) refers to the transmission of data signals for some IP based terminals (such as IP telephones, wireless LAN access points AP, network cameras, etc.) without making any changes to the existing Ethernet Cat.5 cabling infrastructure. At the same time, can also provide DC power supply technology for such equipment 4SAFE AND EFFICIENT: POE technology can ensure the normal operation of the existing network while ensuring the safety of the existing structured cabling, providing efficiency and cost saving 5NO FAN, NO NOISE: The whole machine has no fan design, all aluminum chassis and heat dissipation teeth dissipate heat, the heat dissipation effect is more outstanding, and also dustproof, shockproof, electromagnetic and interference resistant 6QUALITY ASSURANCE: Before leaving the factory, each machine will undergo a strict high temperature aging test for more than 24 hours to ensure that each machine is qualified
