JINYI Features: 1. With delay pull-in, delay disconnection, self-locking and trigger delay functions; 2. With power supply anti-reverse connection function, reverse power supply will not damage the module; 3. There are 5V/12V/24V three There are various working voltage versions for users to choose; 4. The timing can be arbitrarily set between 0.1 seconds and 120 seconds; 5. The parameters can be saved, and the setting content will not be lost when the power is turned off. 1. Module function, the user can select one of the following 4 functions by pressing the button, and can choose the delay time by adjusting the potentiometer. The delay time T1 can be adjusted between 0.1 seconds and 120 seconds. Power-on delay pull-in: After delaying T1 time from power-on, the relay pull-in, give a high-level pulse signal to X1 interface at any time, this function resets and restarts operation; Power-on delay disconnect: power-on When the relay pulls in, the relay is disconnected after T1 is pulled in, and a high-level pulse signal is given to the X1 interface at any time, this function resets and starts running again; self-locking relay mode: give a high-level pulse signal to the X1 interface of the relay , the relay is closed, and then a high-level pulse signal is given to the relay to disconnect. Level trigger mode: the relay is disconnected when the power is turned on, and a high-level signal is given to the X1 interface, and the relay is pulled in immediately. After the X1 port signal disappears, the relay is still pulled in. When the pull-in time T1 arrives, the relay is disconnected. Working voltage: DC 5V, 12V, 24V three options (should not exceed +/-10% of the nominal voltage) Working current: less than 80mA at 5V (less than 1mA when the relay does not operate), less than 35mA at 12V (the relay does not operate) less than 1mA at 24V) less than 18mA at 24V (less than 1mA when the relay does not operate) Operating temperature: recommended -2060 (limit range -3070) Load capacity: Relay normally open port Maximum load capacity: DC 0- 30V/10A, AC 0-250V/10A Relay normally closed port Maximum load capacity: DC 0-28V/10A, AC 0-125V/10A Module interface Module voltage/signal input: There are 3-wire interfaces, all interfaces are wired Terminals, convenient for users to use 1. DC+: Positive pole of DC power supply 2, DC-: Negative pole of DC power supply 3, X1: Input signal detection interface Relay load output: There are 3-wire interfaces, all interfaces have wiring terminals 1, COM: Common to relays interface 2. NO: The relay is normally open interface, the relay is suspended before closing, and short-circuited with COM after closing 3. NC: The relay is normally closed interface, the relay is short-circuited with COM before it is closed, and it is left in the air after it is closed. Quantity: (1 pack) Delay relay module 24V, other products not included Size: 60mm*35mm*20mm (L*W*H) (for reference only) Color as shown Note, because there may be color and size differences between the light effect photos and the actual product, please allow 1-2 cm error
