Multi-bus industry field controller assembly structure

The utility model provides a multi-bus industry field controller assembly structure which comprises a circuit installation box and an interface installation seat. A pin structure is arranged on the lower end of the circuit installation box. A bus bar structure is arranged on the upper end of the interface installation seat. DB15 interfaces are respectively arranged on opposite positions on left and right sides of the interface installation seat. The DB15 interface on one side is a male interface. The DB15 interface on the other side is a female interface. Two to six RJ45 interfaces are arranged at the bottom of the interface installation seat. The multi-bus industry field controller assembly structure has the advantages that Ethernet communication redundancy, CAN communication redundancy, serial communication redundancy and other various redundancy technologies are integrated in a field control device; communication interfaces of various bus protocols are integrated into a whole body; a control circuit and the communication interfaces are independently arranged; circuit replacement and upgrade are convenient; and parallel expansion of multiple controllers can be realized.
