Product Details:

Functional Devices INC / RIB RIB2421B enclosed power relay is ideal in control systems where reliable switching and control of electrical loads are essential. This relay is suitable to actuate or interrupt power to devices, such as lights, motors and other electrical components. It is used for controlling electrical loads in HVAC, lighting and other building automation systems.

Working Mechanism:

  • When a current flows through the coil (electromagnet) of the relay, it generates a magnetic field.
  • This magnetic field attracts an armature or an iron core, causing a set of contacts (switch) to move. The movement of these contacts either completes or interrupts the circuit.
  • The state of the contacts (open or closed) controls the flow of current in the main circuit connected to the relay.
  • Relays are often used to control a high-current circuit with a low-current signal. For example, a small control voltage can activate the relay, which, in turn, switches a larger load.

Features:

  • Functional Devices INC / RIB RIB2421B enclosed power relay features a surface-mounted design, providing ease of installation and accessibility.
  • This relay has wire lead electrical connections, ensuring a secure and reliable power interface.
  • It is equipped with an LED indicator for quick visual status checks.
  • This relay boasts a rapid response time of 18 milliseconds, enhancing its efficiency in controlling electrical loads.
  • Its enclosed sealing enhances durability and protects internal components.
