Item Type: Time Delay Relay Module Control Terminal: There is a 3-wire interface, all interfaces have wiring terminals, which is convenient for users to use 1. DC+: DC power supply positive (5V, 12V and 24V modules are available) 2. DC-: negative pole of DC power supply 3. CH1: Input detection interface 1, active at high level 3. CH2: Input detection interface 2, active at high level Relay Output Terminal: 6-wire interface, all interfaces have wiring terminals 1. NO1: Relay normally open interface 1, hang in the air before the relay is closed, and short-circuit with COM1 after it is closed 2. COM1: Relay common interface 1 3. NC1: Relay normally closed interface 1, short-circuit with COM1 before the relay is closed, and hang in the air after being closed 4. NO2: Relay normally open interface 2, hang in the air before the relay is closed, and short-circuit with COM2 after it is closed 5. COM2: Relay common interface 2 6. NC2: Relay normally closed interface 2, short-circuit with COM2 before the relay is closed, and hang in the air after being closed Load Capacity: Maximum load capacity of normally open port: DC 0-30V/10A, AC 0-250V/10A Maximum load capacity of normally closed ports: DC 0-28V/10A, AC 0-125V/10A The user can select one of the following 20 functions through the button and display, and can set and save the function parameters, or view the current function parameters. The time parameter setting can be adjusted at least 0.1 second, and the accuracy is better than 0.01 second. Setting operation instructions can be obtained from the seller. Reminder: Function 1-8 will start automatically when power on, function 9-18 needs high-level pulse signal (high-level duration is not less than 20ms, the same below) to trigger the start, function 19-20 needs continuous high-level . Function 1: Timing pull-in: After power-on, delay T1 time relay pull-in, T1 is adjustable between 0.1 second and 270 hours, give a high-level pulse signal to the CH1 interface, and repeat the function more than once; Function 2: Timing off: when power on, the relay is closed, the delay time T1 time relay is off, T1 is adjustable between 0.1 second and 270 hours, give a high-level pulse signal to the CH1 interface, and repeat the function more than once; Function 3: Timing pull-in and then disconnection: After power on, the relay does not pull-in first, the relay pulls in after the delay time T1 arrives; the relay disconnects after the pull-in time T2 arrives, and the delay times T1 and T2 are between 0.1 second and 270 hours. Adjustable, give a high-level pulse signal to the CH1 interface, and repeat the function more than once; Function 4: Timed disconnect and then pull-in: After power-on, the relay pulls in immediately, and the relay is disconnected after the delay time T1 arrives; the relay pulls in after the disconnection time T2 arrives, and the delay times T1 and T2 are between 0.1 seconds and 270 hours. Adjustable, give a high-level pulse signal to the CH1 interface, and repeat the function more than once; Function 5: Infinite loop timing mode 1: After power-on, the relay does not turn on first, and the relay turns on after the delay time T1 arrives; the relay turns off after the turn-on time T2 arrives, and then repeats the above state, the delay time T1 and T2 are at 0.1 Adjustable between seconds and 270 hours, a high-level pulse signal to the CH1 interface can restart the above functions; Function 6: Infinite loop timing mode 2: After power-on, the relay will be closed immediately, and the relay will be disconnected after the delay time T1 is reached; the relay will be closed after the off time T2 is reached, and then repeat the above state, the delay time T1 and T2 are within 0.1 seconds -Adjustable between 270 hours, a high-level pulse signal to the CH1 interface can restart the above functions; Function 7: Limited cycle timing mo
