Problems solved by technology

[0002] When the relay output contacts of the TC temperature controller are frequently turned on and off, the DT1 coil is powered on or off. Because the DT1 coil is an inductive element, there will be charging and discharging phenomena during the process of gaining and losing power. When the TC output contacts are frequently operated Adhesion or poor contact due to oxidation may occur

Abstract

The invention discloses a protection circuit of a temperature controller output contact. The protection circuit of the temperature controller output contact comprises a temperature controller, a direct current electromagnetic relay and a direct current power source are sequentially connected between the two output ends of the temperature controller in series, the direct current electromagnetic relay is further in parallel connection with a diode, and the negative electrode of the diode is connected with the positive electrode of the direct current power source. The protection circuit of the temperature controller output contact can effectively protect the relay output contact of a temperature controller, and prevent poor contact caused by contact adhesion or oxidization.

Description

technical field [0001] The invention relates to a protection circuit for an output contact of a temperature controller. Background technique [0002] When the relay output contacts of the TC temperature controller are frequently turned on and off, the DT1 coil is powered on or off. Because the DT1 coil is an inductive element, there will be charging and discharging phenomena during the process of gaining and losing power. When the TC output contacts are frequently operated Adhesion or poor contact due to oxidation may occur. Contents of the invention [0003] The purpose of the present invention is to provide a protection circuit for the output contact of a temperature controller, which can effectively protect the relay output contact of the temperature controller, and prevent contact adhesion or poor contact due to oxidation. [0004] In order to achieve the above object, the technical solution of the present invention is to design a protection circuit for the output con...
