What should we pay attention to when using time relay?

1) Keep the time relay clean, otherwise the error will increase.
2) Before use, check whether the power supply voltage and frequency are consistent with the voltage and frequency of the time relay.
3) Select the control time of the time relay according to user requirements.
4) For DC products, pay attention to wiring according to the circuit diagram and pay attention to the polarity of the power supply.
5) Try to avoid using it in places with obvious vibration, direct sunlight, moisture and contact with oil.
