Hi Current Relays


A relay is an electronically operated switch that is remotely activated by an electromagnet which pulls a set of contacts to either make or break a circuit. Relays are commonly used for – among other functions – switching signals, radio frequencies, high current circuits when using a lower current circuit, and loads such as resistive, motor, lamp, inductive, and capacitive applications. This is helpful when an in-line switch or existing circuit does not have the capacity to handle the required current.

Functions of Relays

  • Galvanic separation of the primary or actuating circuit and load circuits
  • Single-input/multiple-output capability
  • Separation of different load circuits for multi-pole relays
  • Separation of AC and DC circuits
  • Interface between electronic and power circuits
  • Multiple switching operations – time delay, signal condition, among others
  • Serves as an amplifier

High Current Relays: Safely connect and disconnect

High-current relays are a common type of electromechanical relay used to switch and carry high currents. Those relays are often either connected directly to load cables by screwing connections or mounted onto a lead-frame. Automotive high-current relays are engineered for use in vehicle batteries, battery management, battery disconnection, start/stop systems, high performance electrical heaters, and drives and pumps for system voltages up to 48V and currents up to 200A within the automotive market.
