Power Relays, Over 2 Amps
The FCB-405-0521M relay is a power relay for applications where currents exceed 2 amps, such as motor control, heating, and lighting. It features an aluminum oxide (Al2O3) ceramic body and a highly reliable contact mechanism. It is designed for long-term reliability and optimized for a variety of applications.
Design
The FCB-405-0521M is a single-pole single-throw (SPST) type relay. It features a two-terminal coil that is energized to switch the relay on and off. The bottom portion of the relay is an encapsulated enclosure, while the two contacts are soldered to the top of the device. The contact mechanism is made from cadmium-gold alloy, which has superior wear and corrosion resistance.
Contacts & Coil
The contacts of the FCB-405-0521M are rated for currents up to 2A @ 24V DC. These two normally open contacts are capable of providing high-reliability switching performance. To switching on or off, a DC voltage is applied to the two-terminal coil, and the contact mechanism is activated. The coil is rated for up to 6V DC and has a resistance of 250 ohms.
Applications
The FCB-405-0521M relay is designed for applications where current exceeds 2 amps. It is used in a variety of motor control, heating, and lighting applications. Some examples include stage lighting, port automation, industrial automation, HVAC systems, motor control, and motor protection.
Working Principle
The FCB-405-0521M relay works by applying a DC voltage to the coil, which generates an electromagnetic field. This field attracts the contact mechanism to open or close, depending on the direction of current flow. The contact mechanism is held in either the open or closed position until the voltage is removed, allowing the contact to return to its original position.
Advantages
The FCB-405-0521M relay offers several advantages over other relays:
- A rugged Al2O3 ceramic enclosure and high-reliability contact mechanism
- High-reliability switching performance
- High surge and overload current ratings
- High-temperature operation up to 85°C
- Long operating life
Conclusion
The FCB-405-0521M is a high-performance power relay designed for applications where currents exceed 2 amps. It is suitable for a variety of applications such as motor control, heating, and lighting control. The relay is rated for up to 6V DC, has an impedance of 250 ohms, and features a cadmium-gold alloy contact mechanism for long-term reliability. With its robust design and reliable performance, the FCB-405-0521M is an excellent choice for many applications.
