A relay is an electrically operated device. It has a control system and (also called input circuit or input contactor) and controlled system (also called output circuit or output contactor). It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to controlling a high-current circuit with a low-current signal.

  • Optocoupler isolation
  • Good in safety In power system and high voltage system, the lower current can control the higher one, able to control various appliances and other equipment with high-current current.
  • Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
  • Indication LEDs for Relay output status.
  • With a normally-open (NO) and a normally-close (NC) contact.
