One 、 purpose

Two position relay RXMVB2 R251 204 110DC It is used in industrial control and other general control occasions that require large capacity bistable contacts

Two 、 characteristic

Small volume , Easy to assemble and disassemble , It can be installed in places with limited position . It is used in industrial control and other controls that need large capacity bistable contacts , Multiple switching is required on the secondary side and tripping of current transformer . The coil circuit is connected in series with a cut-off contact . Eliminates persistent power consumption , Thus, the heat accumulation is limited and the load of the control power supply is reduced . Coil excitation can be AC or DC .

3、 ... and 、 Action principle

DCS-10(RXMVB2) Series large capacity locking relay makes the bistable relay locked by permanent magnet . The relay consists of a magnetic system , Contact system , The support consists of three parts , The magnetic system consists of two coils , The middle column permanent magnet and iron core form a double port magnetic circuit , When one of the left and right coils is energized , The magnetic field produced by the coil repels the permanent magnet , The armature is switched to the other side, which is locked by the magnet and drives the contact to switch . The contact adopts bridge contact , Large breaking capacity . The shell adopts imported

Combi?ex Protruding modular insertion structure .

Ordering instructions

The relay model and specification must be indicated when ordering Structural form code Wiring mode before or after the board .

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 .

advantage ：

1、 After the state transition, it is no longer necessary to maintain the electromagnet attraction and consume energy , There is also no noise and magnetic field influence that may be emitted when the electromagnet works continuously .

2、 Structural complexity reduces energy consumption and environmental protection .

3、 It can be seen as a relay with holding magnets in both positions , Even if there is no electricity , The relay will also maintain its current state ; Unlike ordinary relays , When the power is on NO（normalopen）, Power off and return to NC（normalclose）.

4、 Energy saving , Switching takes only a few milliseconds to power up
