    Asymmetric Cycler Timer Relay, SPDT, AC/DC 12V-240V

    $56.91
    The asymmetric cycler time delay relay has 1×SPDT/ 2×SPDT these two output types. It has a separate delay setting function and can be set in an ultra-wide delay range of 0.1 seconds to 100 days, which can automatically switch the circuit opening and closing state in two different time intervals to achieve intermittent operation of the equipment. In addition, by short-circuiting S-A1, different working modes can be switched. Timed or intermittent fine control and protection of equipment in the power system can be achieved.

    The asymmetric cycler time delay relay is an electrical control device that can be easily installed on a DIN rail. It has an LED light to display the device status and has a 10-position delay range to choose from. It automatically detects faults and can quickly cut off the power supply to the faulty part to prevent the expansion of the fault. It improves the reliability and stability of the power system and reduces the workload of operators.

    Feature

    • 2 time functions:
    • Cycler beginning with pulse
    • Cycler beginning with pause
    • Function choice is done by an external jumper of terminals S-A1.
    • Time scale 0.1 s - 100 days divided into 10-time ranges: (0.1 s - 1 s/ 1 s - 10 s/ 0.1 min - 1 min/ 1 min - 10 min/ 0.1 hrs - 1 h/ 1 hrs - 10 hrs/ 0.1 day - 1 day/ 1 day - 10 days/ 3 days - 30 days/ 10 days - 100 days).
    • Relay status is indicated by LED.
    • 1-MODULE, DIN rail mounting.

    Tips: In terms of working principle, the asymmetric cycler timer relay can achieve the following functions:

    • Through the preset action time and release time, the circuit can be timed and controlled, such as turning on or off certain equipment at a specific time every day.
    • When a fault occurs in the power system, the relay can act according to the predetermined program, cut off the fault circuit, and protect the safety of the equipment and system.
    • In some application scenarios, the equipment may need to work intermittently to prevent overheating or other potential problems. The relay can perform switching operations within the set time interval.
    • The relay can control the circuit according to the set cycle mode, such as repeatedly opening and closing.
