Solid State Relay 24V AC Switch with Galvanic Isolation Reference Design
Texas Instruments
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.
