Description

The solid state relay 24V AC Switch reference design is a single relay replacement that enables efficient power management for a low power alternative to standard electromechanical relays.  The OFF-mode provides energy to the system controller and the ON mode can switch fast enough to allow backup battery charging where electromechanical relays cannot.  The internal transformer enables isolation and a voltage multiplier ensures enough current to control other relays in the rest of the system.

Features
  • Single electromechanical relay replacement
  • Low power solid state relay with silent operation
  • No clicking noise
  • <1µs Turn-on and Turn-off switching time
  • In OFF-mode, 24-VAC line provides energy to the system
  • <200µA consumption in OFF-mode
  • Cost efficient BOM
