?<strong>Features:</strong> <br>LED 3 digits display£¬ intelligent control£¬ time relay/delay function. <br>Realize high frequency£¬ fast on-off circuit. <br>During the on-off process£¬ will not produce any noise. <br>No electric spark£¬ no electromagnetic interference. <br>The last setting parameters can be memorized after power off. <br>Signal terminal voltage signal can be maintained for a long time. <br>Applied to control motor£¬ bulb£¬ LED light string£¬ mini pump£¬ etc. <br><br>Working modes selection: after power on£¬ long press K1 for 2s£¬ later into the selection of modes: P1~4; K2 to enter the mode. <br>P-1: Monostable trigger delay£¬ a signal to trigger relay£¬ time is up£¬ the relay disconnect; <br>P-2: A signal trigger and countdown begins£¬ T1 seconds after£¬ the relay open T2 seconds£¬ then close; <br>P-3: Open T1 seconds£¬ disconnect T2 seconds£¬ infinite loop. Users can set the relay time T1 and T2; <br>P-4: The relay opens when a signal triggers£¬ when the trigger signal disappears£¬ digital countdown begins£¬ and the relay closes when the time is up. <br><br><strong>Specifications:</strong> <br>Display: LED Digital Display <br>Timing Range(Settable): 0.1~99.9 seconds; 1~999 seconds; 1~999 minutes <br>Working Voltage: DC 5~30V (Common Use 12/24V) <br>Signal Voltage: DC 4~27V <br>Output Capacity: DC 5~30V£¬ Max.
