DC 12V time delay relay module with 8 selectable time ranges Benefits and features Precise timing control: 8 selectable time ranges provide flexible delay options for turnon or turnoff sequencing. Delayed on or delayed off: can be set to delay the activation of a load or the deactivation, enabling various automation scenarios. Reliable protection: builtin power reversal protection diode enhances durability and protects the module during improper connections. load compatibility: supports up to 250V AC at 10A or 30V DC at 10A, suitable for a wide range of power systems. Easy adjustment: a delay adjustment potentiometer lets you set the desired delay quickly by turning clockwise. Specifications and capabilities Supply voltage: DC 12V Time ranges: 8 selectable ranges Delay control: adjustable via potentiometer (rotate clockwise to increase delay) Protection: power reversal protection diode Load capability: up to 250V AC 10A or 30V DC 10A Applications: suitable for timing and sequencing tasks in electrical and automation projects Use scenarios Lighting control: set a delay on to prevent inrush or to create a gradual lighting ramp in outdoor or architectural lighting systems. Pump or fan control: implement a delay off to allow a cooldown period after turning a motor off, improving equipment longevity. Sensortoactuator sequencing: trigger an actuator after a sensor input with a defined delay, enabling orderly process steps in automation or safety interlocks. Notes This module is designed for 12V DC operation and provides flexible timing with protection for reliable performance in both AC and DC load scenarios within its rated limits.
