Two position relay JDP-1440/DC110V

Static guide rail two position relay is used in various protection and automatic control devices that need large capacity bistable contacts , As a switch 、 To achieve the locking effect , With position indication . It is an updated product of the old electromagnetic two position intermediate relay in power system and automation control .

Two position relay , As the name suggests, it means that the relay has two positions , At the same time, it can keep itself in both positions . actually , The two position relay is a magnetic holding relay with two coils .

coil A After power on , Relay contacts act , Even if it loses power , The contacts do not return ; coil B After power on , Relay contact return , Even if it loses power , The contacts will no longer act . in other words , If the contact position of the two position relay is reversed , There must be a coil live .

Two position relay is common in secondary circuit of substation , Mostly used to maintain status 、 In the circuit with high reliability requirements . Such as voltage switching circuit of double bus connection and voltage parallel circuit .

“ 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 make the series connection point of the two coils Set switch , The original normally closed contact is open , De energize the coil , The original normally open contact is closed , At the corresponding coil Ready to power on . Because it is held mechanically by a magnet , Therefore, after the control power supply disappears, its position will remain in the control position The state before the power supply disappears , It will not return to the original state after power loss like the electric hold relay .”
