Description With the start / stop function, after the start of the module into the infinite loop mode, the relay work in accordance with the set time.It is a timer relay module with high precision, stable and reliable performance.There is a wide time range that you can set, both RUN time and STOP time are adjustable. Support start/stop function, module enter an infinite cycle mode after on, relay works according to the setting run and stop time.It is great to control the reciprocating stroke, or repetitive on and off for equipment and products burn-in test.Widely used on timer operating equipment, machine repetitive test circuit,fish tank intermittent pump, etc.Working model : press the start button to start the cycle, and then press the start button to stop working.Start the Cycle mode : On - Off - On - Off Voltage: AC 100V-250V , can be used for 100V/110V/120V/127V/220V/230V/240V . consumption: Less than 10WOutput: Active output, output voltage equals to input voltage.Max. Output Current: Less than 10AInput: Passive switch input, green led lights up after turn on, red led lights up after stopTime Range: 05 seconds -1000 minutesTime Accuracy: Max. range value*0001 (resolution of 1000 ).Input(start button): Passive switch input, green led lights up after turn on, red led lights up after stop- starting the input is not necessaryYou can connect the two terminals 2 terminals with a short wire and then the board will cycle infinitely loop ( no buttons)after on.Life: 100 thousand timesMaterial: PC+Metalcolour: As shownPackage Contents:2 x Dual Time Adjustable Cycle Delay Timing Relay Repeat ON OFF Switch Infinite Loop Timer ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
