Blister packaging machine time relay parameter setting

In actual use of the time relay, it is often necessary to continuously adjust the control time. In order to ensure that the time is adjustable, the oscillator circuit Rt can choose an X-type adjustable potentiometer with better linearity. The delay capacitor can choose CBB polypropylene capacitor with good stability, and the delay scale of the time relay label can be determined according to the selected deflection angle of the mechanical stroke of the adjustable potentiometer, so that the set time value (the value of the label scale) and the The actual delay value is matched to reduce the setting error.
