This Allen Bradley 2711T-JBIP20DC supplied by Hanyite is an industrial junction box. Its task is very pure, which is to serve as a connection hub to link the operator terminal (HMI) of the MobileView series with the on-site power supply, network and other USB devices. It is like a porous socket board, neatly gathering various cables together and then connecting them to the HMI host through a main cable.
