What it does and why you need it Industrial Timer Module with LCD display and switch relay provides precise, repeatable timing control for automation, testing, and smart device projects. It solves inconsistent timing, wiring compatibility, and interference problems so your equipment runs reliably and predictably. Key benefits Wide voltage compatibility: Accepts DC 6–30 V and includes a USB 5 V input for flexible power options across different controllers, sensors, and power supplies. resolution timing: Adjustable delay from 0.01 seconds to 9,999 minutes lets you set short pulses or long intervals with fine control. Multiple presets: Store three timing profiles and switch between them instantly to speed setup and reduce manual reprogramming. Reliable switching: Builtin flipflop modes (/low level) with optocoupler insulation reduce electrical interference and protect control signals. Durable operation: Designed for over 100,000 switching cycles and to operate in harsh conditions from 40 to 85 °C. Practical controls: Onunit stop button and a fiveminute automatic lock improve safety and prevent accidental changes during operation. Flexible integration: Multiinterface setup and the USB port make it easy to connect to PLCs, microcontrollers, or standalone power sources. Performance and safety highlights Optocoupler insulation isolates the control input from output switching noise, improving signal stability in electrically noisy environments. The flipflop function supports both level and lowlevel trigger schemes for compatibility with a wide range of sensors and controllers. LCD display gives clear feedback on timing settings and current status for fast verification and troubleshooting. Typical applications Smart home automation: Time lights, pumps, or HVAC triggers with precise delays and saved presets for different scenes. Industrial process control: Integrate with PLCs or relay systems for repeatable batch timing, conveyor controls, or machine sequences. Laboratory and test stations: Run timed tests, dwell periods, or cycling operations that require accuracy and protection from electrical interference.
