1. Power-on delay type, if the 5-pin relay is powered on after the A load is powered on, after the delay, the B load can be switched on, and reset after power failure;
2. Power-off delay type, if load A is powered on, after power-off, the time relay is powered off. After the delay, load B can be switched on and reset after power-off;
3. Automatic reversal type, such as when the time relay is energized, A load is energized first and B is de-energized, and after A is de-energized, B is energized, so that A load and B load can work in turn.
How to choose a 5-pin relay
When choosing a 5-pin relay, generally follow the following rules:
1. According to the needs of the controlled circuit, it is determined whether the 5-pin relay is a power-on delay type or a power-off delay type;
2. Select the voltage of the 5-pin relay attracting winding according to the voltage of the controlled circuit;
3. If the delay requirement is high, the transistor type 5-pin relay or the electric time relay can be selected; if the delay requirement is not high, the air damping type 5-pin relay can be selected.
