Key benefits — why you need this timer relay Precise, repeatable timing for automation tasks: set delays from short pulses up to long intervals so machines and systems operate reliably without manual intervention. Broad power options for flexible installation: works from vehicle/industrial DC supplies or from a USB 5 V source, reducing the need for extra power converters. Robust switching and noise immunity: optocoupler insulation and a rated life of over 100,000 switching cycles mean consistent performance in electrically noisy environments. What it does Function: electronic timer relay with configurable timing profiles and an LCD for clear status and setting confirmation. Timing range: 01 seconds to 9999 minutes, covering a wide range of short and long-delay applications. Memory: LCD display shows current settings and the unit can store three timing profiles for quick recall. Advanced flip flop mode: provides toggle-style control with optocoupler isolation to reduce interference and extend lifecycle. Key specifications and performance Voltage compatibility: DC 6–30 V input range and USB 5 V connection support. Durable switching: designed for more than 100,000 switching cycles. User interface: LCD shows active settings and timing status; three stored profiles allow repeatable setups without reprogramming. How it stands out Versatility: accepts a wide DC voltage range plus USB power so you can use it in vehicles, battery-powered systems, or standard low-voltage installations. Reliability: optocoupler insulation protects control electronics from electrical noise and improves long-term stability. Convenience: three saved profiles and an on-device LCD reduce setup time on the production floor or in field deployments. Practical use scenarios Automated equipment sequencing: control start/stop timing or staged operations on conveyors, packing lines, or small production machines. Pump and irrigation cycles: schedule run times from seconds to days for water pumps and solenoid valves without additional controllers. Test rigs and lab benches: provide repeatable pulse durations and toggle functions for component testing, endurance cycling, or timed diagnostics. Notes for installers Confirm your supply voltage fits within DC 6–30 V or USB 5 V before wiring. Use the LCD and profile memory to save repeatable settings for different tasks; flip flop mode is ideal when you need alternating or latch-style control. The optocoupler-insulated outputs help minimize interference when operating in electrically noisy environments. Functionality, compatibility, and performance are the focus of this timer relay: precise timing, multiple power options, stored profiles, and durable flip flop switching with optocoupler protection for reliable, repeatable automation.
