Working voltage: DC12V (normal working voltage DC10V-16V) Source: DC4V~20V (usual power supply positive trigger, button, PNP sensor, PLC signal, etc.) Output capability: It can control devices within 30v5A or within 220v5A Quiescent current: 20mA, working current: 50mA Service life: more than 100,000 times;<br><br>Voltage input anti-reverse circuit, worry-free wiring. Signal input optocoupler isolation, strong anti-interference ability. Set the parameter to power off permanent memory. Function introduction: P-1: The signal triggers the relay to pull in. When the time is up, the relay is disconnected during the delay. A: Invalid trigger again B: Re-trigger re-clocking C: Trigger relay reset again to stop timing P-2: The signal trigger start timing time T1, the time is up to the relay pull-in time T2 is disconnected (reset) A: Invalid trigger again B: Re-trigger re-clocking C: Start delay without triggering power-on P-3: Cycling: Turn on T1, disconnect T2, infinite loop. For T1 and T2, the time is adjustable; if a parameter is turned ON or OFF, it can be turned on or the power is turned on. A: The relay is turned on immediately after power-on. B: The relay is turned off and then turned on after power-on. P-4: There is signal, the relay is closed, the suction is , the signal disappears, the timing starts, the time is up, the relay is disconnected, during the delay, the signal is given again, the delay is cancelled, the relay is , the signal disappears, and the time is re-timed.
