Usage Tips:Dc 12v Timer Relay, Digital Automation Timing Timer Timing Relay Switch Programmable Timer With Waterproof Cover g20242444699 About this item Programmable AbilityProgrammable timer can perform advanced preset, repeat programs with 17 on/off settings and manual override which can help save energy . Humanized design When using and setting the parameters for the first time, the memory module will automatically save the data set. The battery has a power reserve function, the setting parameters will still be remembered when power cut off. Automatic error correctionThis timer has automatic error correction + 30 seconds per week, with high precision and strong capacity anti-interference. Easy to useIt has a simple construction, button adjustment, easy and simple for everyone to use, and can be mounted on the wall easily and firmly. Wide ApplicationThe timer relay can be used for timing, delay, cycle timing, intermittent timing, etc. Specification: Item Type: Timer Module of relays Material: ABS Purpose: street lamp, solenoid valve, instrumentation, LED display control Operating voltage : DC12V Quiescent current: 20mA Working current: 50mA Signal source: trigger positive, PNP, active high Output capacity: can control equipment within DC 30V5A or AC 220V5A Lifetime: 100,000 times Working temperature: -30~85 List of functions: P-1: Signal triggers the relay to close, time is up, the relay is disconnected, during the timing period R: Trigger again is invalid C: Trigger again to re-time E: Trigger relay again to reset timer P-2: Start delay time T1 signal trigger ut, when the time is up, the T2 relay trigger time is disconnected (reset) R: Trigger again is invalid C: Trigger again to re-timer E : Start timing without trigger power P-3: Recycling use: T1 on, T2 off, endless loop. T1 and T2, the time is adjustable If a certain parameter is 0 when turned on or off, it can realize that the power-on timing is on or the power-on timing is not cycled. P-4: When there is a signal, the relay is closed and held closed, the signal disappears and timing begins. When the time is up, the relay is disconnected. During timing, give signal again, timing is canceled, relay is held
