Solid State Relay 24V AC Switch with Galvanic Isolation Reference Design
Overview
| Topology | Other Topology |
| IC revision | 00 |
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
- <1-μs Turn-on and Turn-off Switching Time
- In OFF Mode, 24-V AC Line Provides Energy tothe System
- <200-μA Consumption in OFF Mode
- Cost Efficient BOM
Typical applications
- HVAC Systems
- Building Automation
- Thermostats
