Module function

The user can select one of the following 20 functions by pressing the button and display, and can arbitrarily combine the linkage mode between the various paths, and can set and save the function parameters. The T1 and T2 time parameters can be set. The time parameter is 1 Adjustable from seconds to 255 hours, the maximum accuracy is better than 0.01 seconds.

When selecting a high level trigger:

Function 1: Power-on delay pull-in: After delaying T1 time from power-on, the relay pulls in and sends a high-level pulse signal to the X interface at any time. This function resets and restarts operation;

Function 2: Power-on delay off: When the power is turned on, the relay is closed. After the T1 time is closed, the relay is disconnected. A high-level pulse signal is sent to the X1 interface at any time. This function is reset and restarts.

Function 3: Timing pull-in and then disconnect: the relay is disconnected at power-on, the relay is closed after the disconnection time T1 arrives; the relay is disconnected after the pull-in time T2 arrives, and a high-level pulse signal is given to the X interface at any time. Function reset and restart operation;

Function 4: Timing disconnection and re-sucking: the relay is closed when power is on, the relay is disconnected after the pull-in time T1 arrives; the relay is closed after the disconnection time T2 arrives, and a high-level pulse signal is given to the X interface at any time. Function reset and restart operation;

Function 5: Infinite loop mode 1: The relay is disconnected at power-on, the relay is closed after the disconnection time T1 arrives; the relay is turned off after the pull-in time T2 arrives, and then the above state is repeated; the X interface is given a high level at any time. Pulse signal, this function resets and restarts operation;

Function 6: Infinite loop mode 2: The relay immediately picks up when power is on, the relay is disconnected after the pull-in time T1 arrives; the relay picks up after the break time T2 arrives, then repeats the above state, and gives a high power to the X interface at any time. Flat pulse signal, this function resets and restarts operation;

Function 7: Limited cycle mode 1: The relay is disconnected at power-on, the relay is closed after the disconnection time T1 arrives; the relay is disconnected after the pull-in time T2 arrives, and then the NX times are repeated. The number of cycles NX is 1-9999. Adjustable between times, give a high-level pulse signal to the X interface at any time, this function resets and restarts operation;

Function 8: Limited cycle mode 2: The relay is closed when power is on, the relay is disconnected after the pull-in time T1 arrives; the relay is closed after the disconnection time T2 arrives, and then the action is repeated NX times, the number of cycles NX is 1-9999 Adjustable between times, give a high-level pulse signal to the X interface at any time, this function resets and restarts operation;

Function 9: Self-locking relay mode: Give the relay X interface a high-level pulse signal, the relay pulls in, and then a high-level pulse signal relay is disconnected.

Function 10: Level trigger relay mode (including delay off function): When the power is turned on, the relay is disconnected, a high level signal is sent to the X interface, the relay is immediately closed, and after the X port signal disappears, the relay still pulls in, when The relay is disconnected after the pull-in time T1 arrives. Note: In this function, if T1 is set to 0 seconds, it will become: X port has a high level signal relay to pull in, and if there is no signal, it will be disconnected immediately.

Function 11: Timing pull-up after triggering: The relay is disconnected at power-on, giving a high-level pulse signal to the X interface, delaying the T1 time relay to pull in, repeating a high-level pulse signal to the X interface, repeating the above functions;

Function 12: After the trigger is turned off: the relay is disconnected at power-on, a high-level pulse signal is sent to the X interface, the relay is closed, the T1 time relay is turned off, and a high-level pulse signal is repeatedly given to the X interface. More than one function;

Function 13: After the trigger, the timing
