Abstract

The present invention relates to the technical field of control devices, and in particular to an explosion-proof loop controller, comprising a assembly housing, an upper cover body and a control module, the assembly housing has an opening, the upper cover body is disposed at the opening of the assembly housing, the control module includes a first PCB board, a control module, and a wiring mechanism, the first PCB board is disposed in the assembly housing, the control module is disposed on the PCB board, the wiring mechanism is disposed at the opening of the assembly housing and electrically connected to the PCB board, the wiring mechanism is used for electrically connecting an external cable and the PCB board, and inside of the wiring mechanism and the assembly housing is jointly enclosed to form with a encapsulation area. Electronic components such as the first PCB board and the control module are enclosed in an explosion-proof sealant, so that even if the electronic components such asthe first PCB board and the control module generate arcs and sparks during operation, flammable gas around the explosion-proof loop controller will not be ignited, significantly improving service safety of the explosion-proof loop controllers.

Description

technical field [0001] The invention belongs to the technical field of control equipment, in particular to an explosion-proof loop controller. Background technique [0002] As a process control device that receives multiple input signals and outputs a single signal, the loop controller is widely used in metallurgy, chemical industry, petroleum, electric power and other industries, especially the connection control of lighting equipment in the petrochemical industry. [0003] In the petrochemical industry, flammable gas and dust often exist in the service environment of the loop controller. Once the internal control module and other electrical components have arcs and sparks, it is easy to ignite the surrounding flammable gas and dust. There are security risks. Contents of the invention [0004] The object of the present invention is to provide an explosion-proof loop controller, aiming to solve the technical problem in the prior art that there are potential safety hazards...
