RS8H-2S-D18 is a type of power relay categorized as "Over 2 Amps" of which its application field and working principle can be best understood by diving deep into the fascinating features that it brings with itself. In particular, this power relay is designed especially for use in motor applications. Its 8 amp contact ratings are perfect for the medium motor rating applications.

Essentially, the RS8H-2S-D18 is a Schmitt-trigger type relay, and can thus be used to control switching with extreme precision. Its built-in input circuit includes a low-power transistor amplifier, which translates to high amplification of electric signals. As a result, the power relay is more accurate in sensing electrical inputs and is particularly suited for applications where a motor needs to accelerate and decelerate effectively.

The RS8H-2S-D18 power relay is suitable for use in both hard and soft switching conditions. In hard switching conditions, it is capable of switching up to 8 amps of power in about 4 milliseconds, which works out to 4,000 amps for a 10-second period. In soft switching conditions, it takes up to 15 milliseconds for the power relay to switch on 8 amps of power. Thus, even in soft switching conditions, it still takes 1,500 amps for a 10-second period.

Apart from switching electrical signals, the RS8H-2S-D18 power relay also offers good protection against overvoltage, short circuits and current peaks. Due to its built-in quenching circuit, it is capable of automatically protecting itself from any overvoltage or current peaks issues, thereby providing total protection to the motor from any damages due to any of these factors.

Another great feature of the RS8H-2S-D18 power relay is its high mechanical durability. It is designed to withstand prolonged contact with the different parts of the machines and its contacts are made from stronger materials, which makes them more resistant to wear. The mechanical life of the relay is estimated to last up to 10 million operations, making it highly suitable for low-maintenance applications.

In conclusion, the RS8H-2S-D18 power relay is an excellent choice in the field of motor applications due to its excellent features and effective working principle. Because of its excellent protective mechanisms, it is highly reliable in protecting the motor and its parts from damage caused by overvoltages and short circuits. Besides, its high switching speeds, mechanical durability, and low-maintenance requirement make it an ideal choice for different motor applications.
