Signal input optocoupler isolation, anti-interference ability. Set the parameters of power and permanent memory. Powerful flash MCU online programming capabilities, according to user needs can contact the manufacturers to customize the functionality. Features: Receives a trigger signal to start the countdown, while the relay, timing the end of the relay to stop working, time to recover to the set, waiting for the next trigger. Instructions: Click K1 enter the time setting, one hundred digital start flashing, then press K2, one hundred the number of changes; then click K1 ten digital start flashing, then press K2, the tens digit changes; then click K1 bit digital start flashing, then press K2, single-digit change; then click K1, exit the setting, LED no longer flashes. Normal digital tube display, press K2, shifting the decimal point, a decimal point indicates 0-999 minutes in 10 bit from 0 to 99.9 seconds with no decimal point represent 0-999 seconds; to this time setting is completed.
