On the application of the supply voltage between (A1) – (A2), time relay (t) commences.
At the end of the time delay the thyristor switches the full supply voltage through to the load connected to (A2) terminal (max-load 0.7A at 20°C).
If the supply voltage is removed during time (t) timer will reset .
A small leakage current 2.5mA passes through the thyristor during the time period. Care should be taken
