Wiring Principle Of Single Function Timer Relay

Single function timer relay is a settable time control unit.Combined with other electrical equipment it can set delay closing or delay opening contacts according to the required time so that the working time of terminal equipment can be controlled.Mainly used in industrial equipment lighting manufacturing and other occasions requiring time control.

Power-on Delay

Model:HYCRT8-A1 AC220V

Functional explanation：

After the relay is energized, firstly delay the energization according to the set time. When the time is up, the (15) (18) line connection lights will be on.

Example Reference：

If the control bulb lights up after 10 seconds, set the time to 10 seconds first. The relay is energized, after a delay of 10 seconds, the bulb will light up.

Operating Mode：

15-18 are normally open, closed after delay.

15-16 are normally off, disconnected after delay.

Delay Off

Model:HYCRT8-B2 AC/DC 24V-240V

Functional explanation：

After the relay is energized, the (15) (18) line is connected, the light is on, and it is disconnected after 10 seconds, and the light is off.

S can contact the point signal to realize the reset function, and can not be connected.

Example Reference：

If the control bulb goes out after 10 seconds, you need to set the time to 10 seconds first. The relay is energized, the bulb lights up, and goes out after a delay of 10 seconds.

Operating Mode：

(15) (18) are normally open, closed when energized, and disconnected after a delay.

(15) (16) is normally closed, disconnected after power-on, and closed after a delay.
