Powerful function, one-button emergency stop function (STOP button), with reverse connection protection, reverse connection without burning, power-off memory. Increased sleep mode, after enabling, No operation within 5 minutes, automatically turn off the display, wake up any button! You can set different OP, , parameters, these parameters are of each other, save the setting parameters automatically power-down save and other functions, almost meet all needs! Working voltage: DC6V-DC30V (wide voltage anti-connection protection) Trigger signal source: high-level trigger DC 3.0V-24V signal ground and system ground to improve the system's anti-interference ability can also short-circuit the ground Output capacity: controllable DC 30V/10A or AC 250V/10A equipment Operating mode: P1 mode: After the signal is triggered, the relay turns on the OP time, then turns off; in the OP time, the following operation P1.1: The signal is triggered again. P1.2: Signal triggers re-timed again P1.3: The signal triggers reset again, the relay is disconnected, and the timing is stopped. P-2: Give the trigger signal, after the relay turns off the time, the relay turns on the OP time. After the timing is completed, the relay is turned off. P3.1: Give the trigger signal, after the relay turns on the OP time, the relay turns off the time, then loops the above action, the signal is given again in the cycle, the relay is disconnected, the timing is stopped; the number of cycles () can be set P3.2: No trigger signal is required after power-on, the relay turns on OP time, the relay turns off time, and the above actions are cycled; the number of cycles () can be set P-4: Signal hold function If there is a trigger signal, the timing is cleared, the relay remains on; when the signal disappears, the relay is turned off after timing the OP; during the timing, there is a signal, and the timing is cleared.
