Abstract
The utility model discloses a bus-based waterproof digital quantity input and output module, which comprises a shell, a main board wrapped inside the shell, and a coupler plug. The shell served as the outer shell of the module is made of waterproof materials. The coupler plug is an aviation plug. A redundancy module connected with both the main board and a slave board is arranged in the shell. The shell served as the outer shell of the module is made of waterproof aluminum material. The redundancy module is formed by a PCB substrate. The waterproof digital quantity input and output module also comprises an LED state indicating unit. The protection grade of the waterproof digital quantity input and output module is as high as IP 65 and the waterproof digital quantity input and output module can be applied to outdoor or hostile environments. The bus-based waterproof digital quantity input and output module also has the hardware redundancy function. Therefore, when the main board malfunctions, the slave board can continue to work. Due to the adoption of the module, the state indication in the form of digital input and output is provided, so that workers can conveniently know the running state. Meanwhile, the connection is realized by means of the aviation plug, so that the connection is reliable.
