One 、 purpose

DLS Two position relay ( Hereinafter referred to as product ) Used in various protective devices , To achieve mechanical locking , With position indication .

Two 、 working principle

3.1 structure

The product consists of two interconnected electromagnetic mechanisms 、 Interlock slider mechanism 、 Position indicator and contact system . Each electromagnetic mechanism consists of a yoke 、 Coil and armature , Interlock

The sliding block mechanism is composed of two sliding blocks and a tension spring .

3.2 working principle

The principle of the electromagnetic mechanism is the same as the clapping relay of the same section , When one of the electromagnetic mechanisms is excited , Its electromagnetic coil generates electromagnetic torque , Snap the armature , The armature drives the interlock

Slider mechanism , When the incentive amount is removed , Due to the function of the interlock mechanism , Keep the armature in one position , meanwhile , The armature drives the contact system , Keep the contact at

In one place . When another electromagnetic mechanism is excited , Keep the armature and contact system in another position . The two electromagnetic mechanisms cannot apply the excitation amount at the same time . Title

Iron action , It drives the position indicator , Indicate where the product is located . The green card indicates the tripping position , The red card indicates the closing position .

Two position relay DLS-34A DC0.5A 220VDC

Working principle of two position relay ; Two coils , Each coil is connected with a contact in series , One normally open and one normally closed , The force exerted by a magnet when there is no electricity , Fix the armature in the initial position , When the coil of normally closed contact station is powered on , When the coil is energized, the armature moves , After the action, the magnet will fix it at the position after the action , At the same time, the armature acts to switch the position of the series contact of the two coils , The original normally closed contact is open , De energize the coil , The original normally open contact is closed , The corresponding coil is ready for power on . Because it is held mechanically by a magnet , Therefore, after the control power supply disappears, its position will remain in the state before the control power supply disappears , It will not return to the original state after power loss like the electric hold relay .
