Power relays are switches used to control the power to an electrical circuit. An RV8H-L-D12 is an example of such a relay that is rated for currents of over two amps. It is a latching type relay that will hold its position until released by an electronic pulse.

The RV8H-L-D12 is a two pole double throw (2PDT) power relay with a contact rating of up to 8A at 250VAC. It has a mechanical travel of 1.2mm, a shock resistance of up to 100G and an operating life of up to 300,000 cycles. The coil voltage range is 3V DC to 24V DC and the coil resistance range is 60Ω - 1000Ω. The contact material is silver-nickel alloy.

The basic working principle of an RV8H-L-D12 relay is fairly simple. When there is no current passing through the coil, the two polarities of the relay are in the neutral state and no power is transferred. When electric current passes through the coil, a magnetic field is created which draws the armature, moving the contacts to either an activated or deactivated position. This enables the transfer of power to a load or device.

In addition to this, relays are also used to provide isolation between two circuits. In this case, power may flow in one direction, but not the other. The RV8H-L-D12 provides this isolation as well as the ability to react quickly to changes in electrical signals. This makes it especially suited for use in autmotive applications, such as relays for controlling lights or electric windows.

For high power applications, RV8H-L-D12 relays are ideal. They are designed with robust construction and heavy duty contact material to handle higher current loads. The latching type design extends their life with minimal power requirements and the two pole, double throw switch provides greater flexibility than standard single pole switches.

In conclusion, the RV8H-L-D12 is a reliable and robust two pole double throw (2PDT) power relay that is suited for high current applications and provides isolation as well as quick response to changes in electrical signals. Its heavy duty construction and robust contact material can handle high currents, while its latching mechanism ensures a long service life and requires minimal power. It is ideal for use in automotive, industrial and commercial applications.
