Withstand voltage type PLC controller with alarm function

Abstract

The invention discloses a voltage-withstanding PLC controller with an alarm function, which comprises a controller main body capable of programming, two groups of wiring ports used for connecting data wires are arranged at the lower end of the front side of the controller main body in a bilateral symmetry manner, and the wiring ports are connected with the data wires. A metal material outer protective shell for protecting the controller main body is arranged on the outer side of the controller main body, a heat dissipation plate is movably mounted in the outer protective shell, and a mounting plate is arranged on the rear side of the outer protective shell. According to the pressure-resistant PLC controller with the alarm function, a novel structural design is adopted, so that the device can rapidly dissipate heat by using an internal heat dissipation plate and a heat dissipation fan in the use process, and a damping effect is achieved by using an elastic effect of an extrusion spring, so that an internal controller main body is protected, and the service life of the controller main body is prolonged. And when the controller is stolen, an internal anti-theft gear is clamped by a movable rack, so that the controller main body cannot be taken out, and meanwhile, a buzzer gives out an alarm sound.

Description

technical field [0001] The invention relates to the technical field of PLC controllers, in particular to a pressure-resistant PLC controller with an alarm function. Background technique [0002] PLC controller is a kind of programmable logic controller, which is widely used in the field of industrial control. Users can edit the corresponding programs according to their own needs to achieve different control effects.
