Precision Timing Relay Closed Cycle Module • Wide adjustable time range from 0.5 seconds to 1000 minutes, allowing precise control for diverse applications. Easily set delay durations for both RUN and STOP periods to match specific operational needs. • Equipped with a start/stop function. Once started, the module operates in an infinite loop mode with the relay cycling on and off according to your configured timing, ensuring consistent automated operation without manual intervention. • Ideal for tasks requiring repeated operation or controlled cycling, such as reciprocating stroke control, periodic equipment poweroff, and product aging or stress testing. • Passive switch input for starting, with clear visual indicators: green light when running and red light when stopped. Input start is optional; simply short the two input terminals to begin infinite loop mode without the need for a start button. • Compact and versatile design suitable for integration into various electrical setups. Performs reliably in scenarios requiring precision timing with minimal downtime. Example applications: 1. Automated industrial machinery cycling for production efficiency. 2. Laboratory aging tests for electronics and mechanical products. 3. Timed control of ventilation fans, pumps, or other devices in repetitive duty cycles.
