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 )
