TRIGGER DELAY FUNCTION: With delay ON, delay OFF, self-locking and trigger delay function.ANTI-REVERSE FUNCTION: With power supply anti-reverse function to prevent damaging the module.DELAY TIME 0.1-120 SECONDS: The delay time can be arbitrarily set between 0.1 seconds and 120 seconds.PARAMETERS CAN BE SAVED: The parameters can be saved, and the setting contents are not lost when power off.Working voltage: DC12V; Working current: less than 35mA at 12V ( less than 1mA when the relay is not operating)Load capacity:normally open port: DC 0-30V/10A, AC 0-250V/10Anormally closed port: DC 0-28V/10A, AC 0-125V/10AWorking temperature: -20~60 (limit range -30~70)Module function:The user can select one of the following four functions by pressing the button. The delay time can be selected by adjusting the potentiometer.Function F1:Power-on delay pull-in: After the delay of T1 from the start of power-on, the relay pulls in and sends a high-level pulse signal to the X1 interface at any time. This function resets and restarts.Function F2:The power-on delay is disconnected: the relay is closed when the power is turned on. After the T1 time is closed, the relay is disconnected, and a high-level pulse signal is given to the X1 interface at any time. This function is reset and restarts.Function F3:Self-locking relay mode: a high-level pulse signal is sent to the relay X1 interface, the relay is closed, and a high-level pulse signal relay is turned off.Function F4:Level trigger mode: When the power is turned on, the relay is disconnected, and a high level signal is sent to the X1 interface. The relay immediately picks up. After the X1 port signal disappears, the relay still pulls in. When the pull-in time T1 arrives, the relay turns off.Colour: blackMaterial:electronic componentSize: 60 x 35 x 20mmPackage Contents:1 x Delay Timer RelayOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
