Abstract

The utility model discloses a bus-based waterproof digital quantity input module, which comprises a shell, a main board wrapped inside the shell, and a coupler plug. The bus-based waterproof digital quantity input module is characterized in that the shell served as the outer shell of the module is made of waterproof aluminum material. A PCB substrate connected with both the main board and a slave board, and having the redundancy function is arranged in the shell. The coupler plug is an aviation plug. The waterproof digital quantity input module also comprises a state indicating unit. The protection grade of the bus-based waterproof digital quantity input module is as high as IP 65 and the bus-based waterproof digital quantity input module can be applied to outdoor or hostile environments. The bus-based waterproof digital quantity input 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 analog quantity input module, the state indication in the form of digital input 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.

Description

Water proof type digital quantity input module based on bus

Technical field

The utility model relates to the digital quantity input module based on bus, more particularly, relates to a kind of mainboard of parcel in housing, the housing and water proof type digital quantity input module based on bus of an attachment plug of comprising.

Background technology

At present, the existing general digital quantity input module based on bus adopts plastic casing, does not have water-proof function, is not suitable for comparatively using under the rugged environment at outdoor or environment.

Summary of the invention

The purpose of this utility model is, a kind of degree of protection that can improve existing product is provided, the water proof type digital quantity input module based on bus of reduce trouble.

The technical scheme that its technical problem that solves the utility model adopts is as described below: a kind of water proof type digital quantity input module based on bus, comprise mainboard and an attachment plug of parcel in housing, the housing, it is characterized in that, described housing is the shell body of Water-proof aluminium material.

Described attachment plug is aviation plug.

According to the utility model of said structure, further, it is characterized in that, comprise also in the described housing that one is connected and connects the PCB substrate with redundancy feature of a slave plate with mainboard.
