　　DZY-212Q intermediate relay is a DC voltage type intermediate relay, and the "DZY" in its model represents the DC voltage type intermediate relay, while "212" may be the specific model identification of the relay, and "Q" may indicate a certain specific specification or configuration. This type of relay has a wide range of applications in the power system, mainly used to increase the number of contacts, expand the control range, and achieve electrical isolation functions.

　　The main structure of DZY-212Q intermediate relay is a valve type electromagnetic relay. Its internal coil is usually installed on a "П" - shaped or "U" - shaped magnetic conductor, with a movable armature above the magnetic conductor, and two rows of contact systems on both sides of the magnetic conductor. When the excitation applied to the relay coil is equal to or greater than its operating value, the armature will be attracted to the guide magnet, and at the same time, the armature will press the contact spring, causing the contact to connect, disconnect, or switch the controlled circuit. When the coil of the relay is powered off or the excitation amount decreases to less than its return value, the armature and contact piece will return to their original positions.

　　In terms of technical parameters, the operating value of the DZY-212Q intermediate relay is usually 30% to 70% of the rated voltage, and the holding voltage should not exceed 70% of the rated holding voltage, and the holding current should not exceed 80% of the rated holding current. The return value shall not be less than 5% of the rated value, which ensures the stability and reliability of the relay during the action and return process.

　　The DZY-212Q intermediate relay has a wide range of applications and can be used in conjunction with other electrical components to achieve complex control logic and timing control. It plays an important role in fields such as industrial automation, power systems, and transportation.
