The HE1AN-P-DC48V is part of Omron\'s series of power relays, intended for control or switching circuits requiring more than 2 Amps of current in their applications. While it features a wide variety of different models with varying operating voltages, capacities, and coil ratings, the HE1AN-P-DC48V is unique in that its operating voltage is 48V DC. The device is a single-pole double-throw (SPDT) relay, with up to 48V DC power to the coil.

Application Field

Since the HE1AN-P-DC48V is capable of carrying more than 2 Amps of current, it is suitable for a variety of industrial and commercial applications, such as motor control, thermostats, heating and cooling, and even consumer electronics. Additionally, its low-voltage handling ability makes it suitable for low-voltage motor control and other similar applications.

Working Principle

The HE1AN-P-DC48V is a latching relay, which means that once an electric current is applied to coil, the relay stays in its current position, even if the power is subsequently removed from the coil. This type of relay is useful in applications such as temperature control, where it is important to maintain a constant temperature in the environment.

The device\'s internal design is based on a single-pole double-throw (SPDT) contact configuration. In this design, two sets of contacts are used for control. When the coil is energized, the contacts maintain their current position, keeping the control circuit in its current state.

The device\'s operation is relatively simple; the coil requires a voltage of 48V to be fully energized. When this voltage is applied, the input circuit of the device is closed, allowing the contacts to take their current position.

The current rating of the device depends on various factors, such as the type of contact material used, the contact area, and the temperature of the environment. The maximum rated current of the HE1AN-P-DC48V is 4.5A. Additionally, the device can support a wide variety of contact materials, and can operate at a temperature range of -25°C to 70°C.

Conclusion

The HE1AN-P-DC48V is a power relay intended for applications requiring high current and low voltage. It is available in a wide variety of sizes, and can support a wide variety of contact materials. Its single-pole double-throw (SPDT) contact configuration makes it suitable for a variety of applications. Additionally, it\'s latching design ensures that the control circuit will remain in its current state, even if the power is removed from the coil. The HE1AN-P-DC48V is an excellent choice for applications requiring reliable, high-current relay switching.
