Power Relays, Over 2 Amps

Introduction

The RV8H-2S-AD48-C1D2 is a power relay designed for switching high currents. It can handle currents in excess of 2 amps, making it suitable for applications such as lighting control, automated industrial process control, or automation of HVAC systems. The contact arrangement and design of the device allows for both latching and non-latching operation, allowing its use in applications that require intermittent operation or fail-safe power cycling. In addition, the low-profile design of the relay allows it to be easily integrated into low-profile switchgear and control panels, reducing the amount of space needed for the control circuit.

Features

The RV8H-2S-AD48-C1D2 has several notable features that make it suitable for a wide variety of applications. It has a rated operating voltage of 440VAC, with a maximum switching current of 8A. It has a contact arrangement of Form A (SPST-NO), with a contact life of 200,000 operations. The device is also able to operate at high temperatures, with a rated operating temperature of -40°C to +110°C. The device is also designed to operate on a shock and vibration environment per the IEC standard 61373.

Design

The RV8H-2S-AD48-C1D2 power relay has a high-performance, low-profile design that makes it ideal for use in switchgear and control panels. The relay has an efficient, robust design, which allows for a high power density and reliable performance over the long term. The contacts are constructed using silver cadmium oxide, which is highly resistant to electrical and thermal shock, and abrasion. This ensures reliable operation in a wide range of electrical environments. Additionally, the device features a direct-attach design, which allows for reliable, plug-and-play integration with other devices.

Applications

The RV8H-2S-AD48-C1D2 is a versatile device and can be used in a wide variety of applications. Its high current switching capabilities make it suitable for applications such as lighting control, HVAC systems, automated industrial process control, and various consumer electronics applications. Additionally, its low-profile design makes it ideal for use in switchgear and control panels, and its shock and vibration resistance makes it suitable for industrial and transportation applications.

Working Principle

The RV8H-2S-AD48-C1D2 power relay utilizes a coil and contact arrangement to switch high currents. The device uses an electromagnetic field generated by an input coil to open and close the contacts. When the coil is energized with the correct current, an electromagnetic field is generated. This field causes the contacts to move, mechanically opening and closing them. When AC power is applied to the coil, the field cycles between a positive pole, and a negative pole, directing the moving contacts to either open or close. When the coil is not energized, the contacts remain in their default position, an open circuit. The device also allows for the use of latching and non-latching operation, by energizing the coil and holding it in the position of your choice. When the coil is energized and held in a certain position, the relay will not change position until it is energized again in the opposite direction. This makes the relay suitable for applications that require the intermittent switching of power or the cycling of power in a fail-safe configuration.

Conclusion

The RV8H-2S-AD48-C1D2 is a high-performance, high-current power relay, designed for switching currents in excess of 2A. It has a contact arrangement of Form A (SPST-NO), and can operate in harsh environments. Additionally, its low-profile design allows for its use in switchgear and control panels, and its shock and vibration resistance makes it suitable for industrial or transportation applications. The device is versatile and can be used in a variety of applications, including lighting control, automated industrial process control, and HVAC systems. Its use of a coil and contact arrangement to switch high currents means that it can be latching or non-latching, allowing for intermittent switching of power or fail-safe power cycling.
