Features: Achieve high-frequency fast frequent on-off circuit. On-off process does not produce noise. No spark. No electromagnetic interference. Long life than conventional electromagnetic relay life. Often used to control motors light bulbs LED lights DC motors miniature pumps solenoid valve. The use of opto-isolated input and output enhanced anti-jamming capability power ensure stability industrial grade board class PLC after setting the parameters of power and can never remember the signal terminal voltage signal can be maintained for a long time. Delay of one second every time there is an adjustable 0-999 seconds 0-99.9 seconds adjustable 0.1 seconds 1 minute adjustable 0-999 minutes customers can easily switch time range and size power saving Delay time of the last set without duplication.
