Static current: 20mA Operating current: 60mA Operating temperature: -25℃-85℃ Power off memory: Yes Product weight: ≈26g, product size: 65 x 34.3 X 17.5 (MM) Manual measurement is for reference only. The actual size is subject to the material object Warm tips: 1. Please select the required V version (according to the relay identification difference above, the relay is 5V instant 5V version) to avoid wrong purchase. 2. The output of relay is passive contact without current output to control the on-off effect of a line. 3. Please input the trigger voltage strictly according to the selected version Instructions for use: Working mode (32 kinds) : P-11: Inching mode with suction and no disconnection. P-12: Self-locking mode, and the relay state is reversed once after each trigger. P-13: When triggered, the relay pulls in and disconnects after A time delay; Invalid trigger during delay. P-14: When triggered, the relay pulls in and disconnects after A time delay; Retiming is triggered during a delay. P-15: When triggered, the relay pulls in and disconnects after A time delay; Accumulative timing is triggered during delay. P-16: When triggered, the relay pulls in and disconnects after A time delay; Trigger reset (relay disconnection) during delay. P-17: When triggered, the relay pulls in during the signal duration, the input signal disappears, and the relay is disconnected after A time delay; During the delay, the relay is triggered again to keep the suction, and the timing stops until the last signal disappears, and the relay is disconnected after the delay of time A. P-18: After the power is switched on, the relay will pull in immediately and disconnect after A second delay; Until the next power cut. P-21: Signal feed, relay suction after delay A time. P-22: Give the continuous signal. After A time, the relay pulls in; The signal disappears and the relay disconnects. P-23: When the signal disappears beyond time A, the relay pulls in; There is a signal, the relay is off. P-24: Give the continuous signal. After A time, the relay pulls in; When the signal disappears beyond time A, the relay is disconnected. P-25: Give the continuous signal. After A time, the relay pulls in; Give the continuous signal again, after A time, the relay is disconnected P-26: Signal is given and the relay is disconnected after absorbing A time; After the signal disappears, the relay pulls in again for A second and then stops P-27: the relay with pulse signal (rising edge or falling edge) is disconnected, and there is no pulse signal. The relay will be absorbed after A time delay (both continuous high level and continuous low level are considered to have no pulse). P-28: After power on, the relay will pull in after delay time A until power off. P-31: After power on, the relay pulls in time A and disconnects time B, infinite cycle; The power is off. P-32: With continuous signal, the relay pulls in A time, disconnects B time, infinite cycle; The signal disappears and the loop is terminated. P-33: Give A signal, the relay pulls in A time, disconnects B time, infinite cycle; Give the signal one more time to stop the loop. P-34: After power on, the relay will pull in after delay time A, and disconnect after pull in time B. P-35: Signal is given once. After delay of time A, the relay pulls in and shuts off after time B. P-36: Give the continuous signal. After A time, the relay will pull in and disconnect after B time. Signal disappeared, time reset, relay disconnected. P-37: There is A signal. The relay will automatically disconnect after it pulls in time A, and then timing time B after it is disconnected. The signal trigger will be invalid within time A+B. P-38: There is A signal. The relay will automatically disconnect after absorbing A time, and then timing B time after disconnecting, and automatically disconnect after absorbing A time again. P-41: No action on signal; Signal vanishing trigger; The relay is disconnected after absorbing the delay time of A. P-42: the signal disappears and the relay pulls in after A time delay; The relay disconnects after B time delay. P-43: The signal disappears, and the relay pulls in after the disappearance exceeds time A; The relay disconnects after B time delay. P-44: After power on, the relay attracts time A and disconnects time B; The relay disconnects and stops after C cycles. P-45: No action after power on; After giving the signal, the relay attracts A time and disconnects B time; The relay disconnects and stops after C cycles. Give the signal, then execute again. P-46: When the signal is given more than A times, the relay pulls in; Keep the suction; The power is off. P-47: When the signal is given more than A times, the relay pulls in; Disconnect after suction B time. P-48: In C time, after continuous signal feeding for more than A times, the relay will disconnect and stop after absorbing B time.
