Power Relays, Over 2 Amps: R10-R2W2-V700 Application Field and Working Principle

R10-R2W2-V700 is a type of power relay with an AC and DC rated voltage of 600V. This type of power relay is designed for applications such as air conditioning, refrigerator, water heater, and air compressor/motor controlling. It is part of OMRON’s R10 series of relay devices, which are designed for power control applications.

The R10-R2W2-V700 is designed for operation in temperatures between -20°C and 70°C (Rated temperature: 30°C). It can be used in environments with humidity levels up to 85% relative humidity. The relay is designed for an electrical connection configuration of two poles, two throws, and a single coil.

Mechanical Design

The mechanical design of the R10-R2W2-V700 is composed of a main contact, two movable contacts, and a metallic enclosure with an integrated switching coil. The relay is constructed from polyamide resin and fitted with silver-nickel alloy contacts to increase contact stability. For improved insulation from electromagnetic fields, the enclosure has an enclosed magnetic sheet.

The mechanical design position of the contacts is vertical, which minimizes the contact bounce time generated when the contacts open. The contacts can switch between the two poles and can activate a single coil. The contact type of the R10-R2W2-V700 is a normally open contact, meaning that the circuit is open until it is activated.

Electrical Design

The electrical design of the R10-R2W2-V700 includes a rated voltage of 600V (AC and DC) and a rated current of 2A. The contact resistance of the relay is 10 mΩ and it has switching capacity of 1000 operations per minute. It also has a high dielectric strength (2500V AC) and a thermal endurance of 85°C (176°F).

Frequently Used Applications

The R10-R2W2-V700 power relay is used in various applications, such as:

• Air conditioning
• Refrigerator
• Water heater
• Air compressor/motor controlling

Working Principle

When the coil of the relay is activated, it creates an electromagnetic field, which attracts the movable contacts towards the main contact. As the contacts approach each other, they close and make an electrical connection. The contacts continue to remain closed as long as the coil remains activated. When the coil is deactivated, the electromagnetic field is removed, and the movable contacts are released back to their original position by the tension of the springs in the mechanism.

In the R10-R2W2-V700, the contacts open and close by the action of software controlled electrical current, and the movement of the contact is smooth and controlled. The contacts are connected to the electrical circuit when they close and the current flows, while opening will stop the flow of electricity to the circuit. This enables the R10-R2W2-V700 to be used in applications requiring precise switching and controlling.

Conclusion

The R10-R2W2-V700 is an AC and DC rated voltage of 600V power relay that is designed for applications such as air conditioning, refrigerator, water heater and air compressor/motor controlling. It is designed with silver-nickel alloy contacts, a single coil, and two poles with two throws. The mechanical contact position is vertical, which minimizes contact bounce time. It also has a rated current of 2A, contact resistance of 10 mΩ, switching capacity of 1000 operations per minute and a thermal endurance of 85°C (176°F). The relay is activated when an electrical current activates the coil, which creates an electromagnetic field and closes the contacts.

The R10-R2W2-V700 power relay is used for a number of applications where precise switching and controlling are required and with its efficient electrical and mechanical design, it is sure to meet the needs of many industrial and consumer applications.
