Timer Relay Module, Switch Delay Adjustable Infinite Cycle On/Off Module (DC12V,0 60min)

This relay module widely used on timer operating equipment, machine repetitive test circuit, fish tank intermittent pump, etc The 12v relay timer is great to control the reciprocating stroke, or repetitive power on and off for equipment and products burn-in test Support 2 modes, mon mode(once) and cycle mode, and you can simply switch mode by adjusting the jumper How to Set Time Quickly: Time can be quickly set by measuring voltage(Uc) of resistor. Take a 5V 15min module as example. If Uc=2V, time=2V/5V*15min=6min. This 12v timer switch is a timer relay module with high precision, stable and performance. There is a wide time range that you can set, both on time and off time are adjustable
