About this item Programmable Ability: Programmable timer can perform advanced preset, repeated programs with 17 on/off settings and manual override which can help save energy. Humanized Design: When using and setting parameters for the first time, the memory module will automatically save the set data. The battery has a backup power function, setting parameters will still be remembered when power is off. Automatic Error Correction: This timer has automatic error correction + 30 seconds per week, with high precision and strong anti-interference capability. Easy to Use: It has a simple structure, button adjustment, lightweight and easy for anyone to use, and can be mounted on the wall easily and securely. Wide Application: The timer relay can be used for timing, delay, cycle timing, intermittent timing, etc. Specification: Item Type: Timer Relay Module Material: ABS Purpose: Street lights, solenoid valves, 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 Service Life: 100,000 times Working Temperature: -30~85 Function List: P-1: Signal triggers the relay to close, time is up, the relay disconnects, during the time period R: Trigger again is invalid C: Trigger again to re-time E: Trigger relay again to reset the timer P-2: Start delay time T1 signal trigger output, when time is up, T2 relay trigger time disconnects (reset) R: Trigger again is invalid C: Trigger again to re-time E: Start timing without trigger current P-3: Recycling: T1 on, T2 off, infinite 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 is on or the power is not cycled. P-4: When there is a signal, the relay is closed and kept closed, the signal disappears and the timing starts. When the time is up, the relay disconnects. During timing, give signal again, timing is interrupted, relay is kept
