Power Relays, Over 2 AmpsThe FCA-410-1621L is a power relay, specifically designed for applications that require currents higher than two amps. It is constructed with a double surface electrode relay, allowing for greater contact and heat resistance than single surface designs. These qualities make it ideal for applications that put it in high-powered, high reliability requirements.The FCA-410-1621L is a latching contact type relay, meaning that when it is actuated it will remain closed or open until a reset signal is applied. It uses a high-performance shunt diode as a timing element to prevent back-EMF energy spikes during switching. The contacts are made from silver and gold plated copper, providing superior electrical conductivity and excellent corrosion resistance.The FCA-410-1621L is designed for use in industrial, HVAC, and automotive applications. It protects electronic components and equipment from electrical overstress, and provides swift and reliable switching. It is also useful in other higher power applications, such as robotics, air-conditioning and other high-precision machinery.In terms of design, the FCA-410-1621L’s coil is molded in plastic, allowing for enhanced physical and thermal protection. The relay features a single-pole double-throw (SPDT) contact arrangement, providing flexibility for switching between multiple loads. The contacts are designed to provide long service life and low-level leakage, reducing the chance of unwanted electrical leakage or shorts. Additionally, the relay meets the standards of IP67 and IEC60529, making it suitable for use in high-temperature and wet environments.The working principle of the FCA-410-1621L is relatively simple. When the current through the coil reaches a certain level, the coil becomes magnetized, thus generating a magnetic field which moves the armature which in turn actuates the contacts. When the current is removed, the magnetic field and armature return to their resting state, disconnecting the contacts.In summary, the FCA-410-1621L is an extremely powerful and reliable relay, suitable for a wide range of applications. Its double surface electrode design and plastic molding allow for enhanced physical protection and electrical performance. Additionally, its robust construction, IP67 rating, and high-performance shunt diode timing element make it suitable for high-temperature and wet environments, and it is ideal for switching high currents.
