Double adjustable time relay (often called an asymmetric cycle or twin timer relay) is a specialized electrical control device that allows users to set two independent timing periods, typically labeled t1 and t2, within a single cycle.
Core Functionality
- Independent Intervals: Users can set separate durations for the “ON” (work) and “OFF” (pause) periods.
- Asymmetric Cycling: Unlike standard flasher relays that have equal ON/OFF times, these allow for unequal intervals, such as 5 seconds ON and 10 minutes OFF.
- Repeat Cycle: The relay continuously alternates between these two states as long as power is supplied.
Key Specifications (Typical for 2026)
- Timing Ranges: Extremely broad, often adjustable from 0.1 seconds up to 10 days or even 999 hours.
- Voltage Compatibility: Wide multi-voltage support, commonly operating on 12V–240V AC/DC.
- Mounting: Primarily designed for 35mm DIN rail installation in electrical panels.
- Interface: Features rotary knobs for analog adjustments or digital LCD displays for precise setting.
