The Siemens VF4A-45H11 is a versatile and reliable 24V DC coil operated reed contact relay. This device is part of Siemens' VF4A series, which is known for its high performance and durability.
The Siemens VF4A-45H11 is designed for applications where a reliable and compact switching solution is required. It features 11 Form C, normally open, SPDT (single-pole double-throw) reed contacts. These contacts are gold-plated to ensure reliable contact performance over time, even in harsh environments.
The relay operates on a 24V DC coil voltage, making it suitable for use in a wide range of industrial and commercial applications. It has a contact rating of 10A at 250V AC or DC, making it suitable for switching low to medium current loads.
The Siemens VF4A-45H11 has a compact size with dimensions of 59.5 mm x 35.5 mm x 22 mm (L x W x H), making it easy to install in confined spaces. It also has a low power consumption of less than 0.1 W when in coil de-energized state, making it an energy-efficient solution for your switching needs.
The relay is also built with robustness and durability in mind. It has a protection class of IP20, which means it is protected against dust and water splashes from all directions. It also has a high operating temperature range of -25 C to 70 C, making it suitable for use in a wide range of environments.
The Siemens VF4A-45H11 comes with a built-in coil overvoltage protection, which protects the relay from damage caused by overvoltage conditions. It also comes with a built-in coil current limiting resistor, which limits the current flowing through the coil during switching, ensuring safe and reliable operation.
Overall, the Siemens VF4A-45H11 is a high-performance, compact, and reliable 24V DC coil operated reed contact relay. It is suitable for use in a wide range of industrial and commercial applications and offers reliable switching performance, even in harsh environments.
