LED Display Relay Module Self-lock Switch with 2 relay

Module Functions: Tips: Function 1-8 on power-up self-start function 9-18 require high pulse signal (high duration is shorter than 20ms, hereinafter the same) trigger the start. Function 1: Timing Pick: After power, time delay relay pull T1, T1 between 0.1 seconds -270 hours adjustable, CH1 interface to a high level pulse signal, repeat the above functions; Function 2: Timing off: when the power relay, time delay relay disconnected T1, T1 between 0.1 seconds -270 hours adjustable, CH1 interface to a high level pulse signal, repeat the above functions; Function 3: Timing pull off again: After power relay to not pull, the delay time T1 reaches the relay is energized; pull the relay off after T2 arrival time, delay time T1 and T2 in 0.1 seconds -270 hours between adjustable, CH1 interface to a High pulse signal, repeat the above functions; Function 4: Timing and then pull off: After power, immediately pull the relay, the relay off delay time T1 after arrival; T2 arrive after disconnecting time relay, -270 hour in 0.1 seconds delay time between T1 and T2 adjustable to CH1 interface a high pulse signal, repeat the above functions; Function 5: Infinite loop timing mode 1: After power relay to not pull, after the delay time T1 reaches the relay is energized; pull the relay off after time T2 arrives, and then repeat the above condition, the delay time T1 and T2 at 0.1 adjustable between second -270 hours, giving a high level pulse signal CH1 interface, you can restart the above functions; Function 6: Infinite loop timing mode 2: After power, immediately pull the relay delay time T1 reaches the relay off; arrive after disconnecting time T2 relay, and then repeat the above condition, the delay time T1 and T2 in 0.1 seconds adjustable between -270 hours, giving a high level pulse signal CH1 interface, you can restart the above functions; Function 7: Finite loop timing mode 1: 5 on the basis of functionality, increasing the number of cycles function, this time between T1 and T2 in 0.1 seconds -9999 seconds adjustable cycles NX adjustable between 1-9999 times to CH1 interface a high pulse signal, the above functions can be re-started; Function 8: Finite loop timing mode 2: 6, on the basis of the function, increasing the number of cycles function, this time between T1 and T2 in 0.1 seconds -9999 seconds adjustable cycles NX adjustable between 1-9999 times to CH1 interface a high pulse signal, the above functions can be re-started; Function 9: Latching relay modes: CH1 interface to relay a high level pulse signal, relay, give a high pulse signal relay disconnected. Function 10: Trigger relay modes: CH1 interface to a high signal relay, relay, high disappear, relay disconnected. Function 11: Pull the trigger timing: After power relay does not act, a high-level interface to CH1 pulse signal, the delay time relay pull T1, T1 between 0.1 seconds -270 hours adjustable, repeating a high level interface to CH1 pulse signal, repeat the above function; Function 12: Trigger timing off: After power relay does not act, a high-level interface to CH1 pulse signal relay, the relay off delay time T1, T1 between 0.1 seconds -270 hours adjustable, repeat to CH1 interface a high pulse signal, repeat the above functions; Function 13: Pull the trigger timing then disconnect: After power relay does not act, CH1 interface to a high level pulse signal, the delay time T1 reaches the relay is energized; pull the relay off after T2 arrival time, delay time T1 and T2 between 0.1 seconds -270 hours adjustable, repeat CH1 interface to a high level pulse signal, repeat the above functions; Function 14: Disconnect and then pull the trigger timing: After power relay does not act, a high-level interface to CH1 pulse signal, immediately pull the relay, the relay off delay time T1 after arrival; T2 arrive after disconnecting time relay, delay time between T1 and T2 in 0.1 seconds -270 hours adjustable, repeat CH1 interface to a high level pulse signal, repeat the above functions; Function 15: Infinite loop timing mode 1: After power relay does not operate to a high level pulse signal CH1 interface, the delay time T1 reaches the relay is energized; pull off the relay arrival time T2, and then repeat the above condition, the extension when the time between T1 and T2 in 0.1 seconds -270 hours adjustable, repeat CH1 interface to a high level pulse signal, the above functions can be re-started; Function 16: Infinite loop timing mode 2: After power relay does not act, a high-level interface to CH1 pulse signal, immediately pull the relay, the relay off delay time T1 after arrival; break time T2 after reaching relay, then repeat the above condition, the delay time between T1 and T2 in 0.1 seconds -270 hours adjustable, repeat CH1 interface to a high level pulse signal, the above functions can be re-started; Function 17: Finite loop timing mode 1: 15 on the basis of functionality, increasing the number of cycles function, this time between T1 and T2 in 0.1 seconds -9999 seconds adjustable cycles NX adjustable between 1-9999 times, repeating to CH1 interface a high pulse signal, the above functions can be re-started; Function 18: Finite loop timing mode 2: 16 on the basis of functionality, increasing the number of cycles function, this time between T1 and T2 in 0.1 seconds -9999 seconds adjustable cycles NX adjustable between 1-9999 times, repeating to CH1 interface a high pulse signal, the above functions can be re-started; Connections: Module control side: there are 3-wire interface, all interfaces are terminal 1, DC +: 12V positive 2, DC-: power in negative 3, CH1: Input Detection Interface Relay outputs: a 3-wire interface, all interfaces are terminal 1, NO: normal open (before relay closes, this pin is not connected. after relay closes, the pin short-connects with COM) 2, COM: Relay Common Interface 3, NC: Normal closed (before relay closes, this pin short-connect with COM. after relay closes, the pin is not connected )
