The time relay is based on the NE555 timer (U1) configured as a monostable multivibrator. Using button B2, the relay is reset and remains in standby mode. A single press of button B1 activates the relay for a preset time period.
The on-time duration is determined by capacitor C4 and trimmer Tr1 and can be adjusted within a range from 0 to 160 seconds. An LED indicates whether the relay is activated.
The circuit includes a start button and a premature stop button, allowing manual interruption of the timing cycle.
