Determining Rb
The current flows into Rb should be enough to turn ON TR when the
relay is reset. When determining value of Rb, the following points
must be noted:
• TR must be sufficiently turned ON even when T equals the time
• Give adequate consideration to changes in the due to changes in
An experiment reveals that the relay sufficiently operates with a
capacitance of 100 μF + 47 μF where the relay is rated at a supply
voltage of 5 VDC and a coil voltage of 3 VDC. It can therefore be said
that the capacitance can be lower than the calculated value. This is
because the time constant is determined with a relatively wide mar-
gin. So it is recommended to perform experiments to determine the
time constant.

here can efficiently control the relay, consuming a tiny amount of
power.
