Adjustable Cycle Timer Delay On/Off Switch Power Supply Relay Shield DC 12V Timer Delay Relay Module (0 -60 Minutes)
Single time mode 1. No action after power on, the relay is turned on after triggering and disconnected after reaching the time. 2 In the delay process after the relay is turned on, triggering again will immediately interrupt the delay.
Cycle Mode 1. No action after energising, relay on after triggering, off after reaching T1 time. After reaching T2 time, the relay will turn on. T1 and T2 are set by two adjustable resistors. T1 and T2 are set by two adjustable resistors. 2 In the time-delay process, trigger again, will immediately interrupt the time-delay.
