Abstract
The utility model discloses a bus-based redundancy type digital quantity input module, which comprises a shell, a main board wrapped inside the shell, and a coupler plug. A redundancy module connected with both the main board and a slave board is arranged in the shell. The redundancy module is formed by a PCB substrate. The shell served as the outer shell of the module is made of waterproof aluminum material. The coupler plug is an aviation plug. The digital quantity input module also comprises an LED served as a state indicating unit. The bus-based redundancy type digital quantity input module has the hardware redundancy function. Therefore, when the main board malfunctions, the slave board can continue to work. The protection grade of the bus-based redundancy type digital quantity input module is as high as IP 65 and the bus-based redundancy type digital quantity input module can be applied to outdoor or hostile environments. Due to the adoption of the 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
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 the waterproof based on bus, redundancy-type digital quantity input module of an attachment plug of comprising.
Background technology
At present, the existing general digital quantity input module based on bus does not have redundancy feature, and when module failure, whole control system must be shut down maintenance, greatly reduces yield-power; And the employing 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, provides a kind of and can improve existing product production efficiency and degree of protection, the redundancy-type digital quantity input module based on bus of reduce trouble.
The technical scheme that its technical matters that solves the utility model adopts is as described below: a kind of redundancy-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, comprise also in the described housing that one is connected and connects the redundant module of a slave plate with mainboard.
Described redundant module is a PCB substrate.
