A time delay relay activates a circuit after a preset delay once power is applied, and is commonly used in HVAC, lighting, and industrial automation systems.
- Delays circuit activation after power-on
- Adjustable time range (typically from milliseconds to minutes)
- Compact and easy to install
- LED indicator for timing status
- Reliable solid-state or electromechanical design
- Ideal for compressor protection, sequencing loads, and startup delay
