1 purpose

The relay is mainly used for switching and locking as a large capacity bistable element in DC operated relay protection and automation circuits .

2 characteristic

The relay adopts imported magnetic holding relay , It has a step-down valve inside , Show , Outlet three circuits , No setting , Convenient and intuitive . And there are various export modes .

The relay is composed of imported magnetic holding relay , Using the magnetic holding characteristic of the relay itself, the relay can realize the choice of two action positions

Switch between , The interlocking relationship between the electric shock of the relay is used to realize the restriction and protection of the reset circuit and the action circuit . Imported magnetic protector

Hold relay .

5 Usage method

RXMDl Use two digits to represent ,RXMD2 Use three digits to represent

stay 212 (11) and 211 (21) After the terminal is connected to the DC power supply, it is marked on the panel to indicate the power supply 212 (11) -211 (21) Of

Light emitting diodes give off light . Outlet relay operates , The status of the rear terminal is opposite to that of the panel . Otherwise, it indicates that the DC circuit of the relay has

fault .

stay 122 (12) and 211 (21) After the terminal is connected to the DC power supply, it is marked on the panel to indicate the power supply 122 (12) -211 (21) Of

Light emitting diodes give off light . Outlet relay operates , The status of the rear terminal is the same as that of the panel . Otherwise, it indicates that the DC circuit of the relay has

fault .

Two position relay RXMD2-1MRK001984 DC220V

Electromagnetic two position relay has voltage reset and red 、 The green sign indicates , The closed magnetic circuit is composed of two electromagnets and a common armature , One end of the armature is limited by a spring piece .

When the closing coil is energized , The armature overcomes the reaction force of the shrapnel , At this time, the signal board is red . When the closing coil is powered off , Due to the effect of shrapnel , Keep the armature in the closing position . Only when the trip coil is energized , The armature overcomes the reaction force of the spring piece and is attracted to the tripping position , At this time, the signal board is green . When the trip coil is de energized , Due to the restriction of shrapnel , The armature is still in the trip position . Therefore, the purpose of locking is realized .
