H3Y4 Time Delay Relay DC12V 060s Adjustable Timer Relay for Automation Precise Time Control

H3Y4 Time Delay Relay A compact, easy to set time delay relay designed for general purpose control in low power DC systems. The H3Y4 series provides reliable timing control, simple rotary adjustment, and a sealed housing for stable performance in common automation and household applications. Key benefits Accurate, adjustable timing: Rotary pointer knob and clear printed scale let you set delay precisely and quickly. Flexible voltage options: Available in multiple models and voltages to match your system needs, including DC12 and AC12 variants and a 24V option. Durable construction: Flame retardant, thickened shell with a smooth, burr surface for safer handling and longer life. Protected design: Sealed housing helps keep internal components from dust and contaminants for more consistent operation. Low power switching: Contact load designed for low power circuits, suitable for control signals and small loads. Main features Model: H3Y4 time delay relay. Time range example: 0 to 60 seconds on DC12V model; additional time ranges available across models. Power source: DC (with AC models available in the series). Working principle: Time relay for delayed switching operations. Contact load: Low power suitable for control and signal level applications. Protection: Sealed enclosure. Build: Flame retardant material, thickened shell, smooth finish, clear scale for easy reading and setting. Typical applications Industrial automation: Sequencing and timing control for conveyor systems, machine cycles, and process automation. Lighting and control circuits: Delayed switching for lighting systems, indicator circuits, and timed control panels. Ventilation and motor control: Start delay or runon timing for blowers, small motors, and fan systems to prevent inrush or provide controlled operation. Compatibility and selection tips Choose the model voltage that matches your control circuit, for example DC12V for the noted 0 to 60 second range or 24V where specified. Use this relay where low power contact switching is required rather than direct current loads. Check the specific model time range and voltage before installation to ensure correct match with your application. The H3Y4 series offers a practical, durable, and easy to configure timing solution for a wide range of control tasks.
