HE1AN-S-DC12V Application Field and Working Principle

The HE1AN-S-DC12V on-off power relay is a normally open type (NO) multipole latching relay designed to switch “big” currents at up to 2 Amps per contact. It is applied mainly in the field of Heavy Duty Load Control. With quick and reliable switching capabilities, the HE1AN-S-DC12V is an ideal choice for applications where switching time is not a major consideration.

Overview of HE1AN-S-DC12V

Designed for cost efficiency and reliability in mission-critical Heavy Duty Load Control applications, the HE1AN-S-DC12V is a multiple contacts latching relay that can switch big current loads of up to 2 Amps. This kind of relay also features a self-latching coil system that can certainly contribute to an improved power efficiency and a streamlined, self-powered, low-power/small-footprint circuit design.

Application Field

Typical applications of the HE1AN-S-DC12V include motor switching, reversing, and controlling; contactor switching and controlling; DC motor speed control; lighting control and management; industrial robotic control; remote control operating power switch; door and gate locking and unlocking; heater switching and controlling; and dimmer and resistor control. It is also ideal for applications needing fast, reliable and silent switching of high current loads, such as those found in medical and industrial automation, communications, and semiconductor processes, where downtime, safety and production efficiency are critical plants.

Working Principle

Basically, the “on” and “off” states of the HE1AN-S-DC12V can be switched by a pulse voltage of 350 mV or more applied to the coil latching terminal. The types of coils with which the HE1AN-S-DC12V can work are DC or AC coils; for the DC case the coil can be energized either from a DC source or AC source.

In order to protect the HE1AN-S-DC12V against an excessive current flowing in the coil, its current sensing unit limits it to 175 mA. This ensures the relay is both efficient and reliable. Also, the HE1AN-S-DC12V can be triggered with a low voltage (under 350 mV) This will make the HE1AN-S-DC12V even more versatile, as it can be controlled from any low-voltage source, ensuring the best combination of reliability and cost-effectiveness.

Conclusion

The HE1AN-S-DC12V multipole latching relay is an ideal choice for applications where switching time is not a major consideration. It is reliable and efficient when it comes to switching “big” current loads up to 2 Amps and is suited mainly for mission-critical Heavy Duty Load Control applications. With its self-latching coil system, the HE1AN-S-DC12V contributes to an improved power efficiency and a streamlined, self-powered, low-power/small-footprint circuit design.
