RXMVB2 HEAVY-DUTYLATCHING RELAY

1 APPLICATION The relay is used in industrial and other general control where heavy-duty double-stable contacts are needed.

1 APPLICATION

The relay is used in industrial and other general control where heavy-duty double-stable contacts are needed.

2 FEATURES

2.1 The relay’s bulk is small which can be mounted in the limited place. It’s convenient to dismantle and load.

2.2 The real is used in industrial and other control where heavy-duty double-stable contacts are needed. It requires more switching in CT secondary side and tripping circuit.

2.3 Break-off contact is in series in coil which can avoid continuous power consumption . So it restricts thermal accumulate and reduces load of control power supply.

2.4 Coil power includes DC and AC.

3 PRINCIPLE OF OPERATING

Series DCS-10 heavy-duty latching relay is double stale relay which relies on permanent magnet latching. are two self-governed signal relay in a smallest case. The relay is electromagnetism beaten-combined type, which is made up of electromagnetic system, contact system and signal display. After add stimulant magnitude to the coil of the relay, gag bit keep in the place of sucked-combined because of magnetic force of magnet. And contact close target displays four horizontal stripes, red and yellow and fluorescence color target. When add short time reset voltage to reset coil, the relay will come back to release.
