Directions for use
1. Use the delay setting potentiometer to preset the delay time. After the power is switched on, the relay starts to delay to the preset time to perform relay conversion to realize timing control.
2. The shortest power on time of ND2A relay should be ≥ 2S, and the power should be switched on after 2s before use to make it delayed release.3. The repeated start interval of relay shall be & GT;0.5 s.
