Product Description:

Adjustable timer 0.1 to 999 minutes, continuously variable.

Module characteristics and uses:

1. Faster switching times when compared to mechanical relays.
2. ON - OFF switching does not produce sparks and thus reduces electromagnetic interference.
3. Eliminates problems associated with relay mechanical contacts.
4. The dual-MOS parallel drive offers lower switching resistance and high current capability. The output can switch loads of up to 15A or 400W.
5. Suitable for controlling lights, LEDs, DC motors, micro-pumps, solenoid valves, etc.

Highlights:

1. Input voltage  -  5 to 36V.
2. The operation of the interface is easy to understand and meets most requirements for timers.
3. An emergency stop function (“STOP” key) is included in the circuit.
4. Reverse polarity protected. Reverse polarity will not damaged the unit.
5. Sleep mode function is available. If this mode is enabled, the unit will enter 'sleep mode' within 5 minutes of the last key operation. While in this mode the unit will wake-up when any key is pressed.
6. OP, CL, LOP parameters can be set independent of each other, and are automatically saved.
7. All parameters are stored in memory and are not lost when the unit is powered down.

Operating mode:

P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows:

P1.1: signal is triggered again, invalid

P1.2: signal is triggered again, the clock is reset

P1.3: Signal trigger again, relay off, stop the clock;

P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay;

P3.1: trigger signal, the relay is turned on after the "OP" time, the relay off "CL" time, then the operation cycle, if the trigger signal period, the relay off, stop the clock; the number of cycles ( "LOP ") can be set.

P3.2: without triggering signal, the relay is on "OP" time, the relay off "CL" time, and has been cycling; frequency ( "LOP") cycle can be set;

P-4: signal holding function. If there is a trigger signal timing is cleared, the relay remains on; when the signal disappears, after the timing "OP" time, the relay is; if another signal during timing, timing is cleared;

 

Product parameters:

1. Operating voltage: 5 to 36V.
2. Trigger Source: Active-high (3.0V-24V), have optocoupler isolation, can improve the system's anti-jamming capability (customers can also shorting common ground).
3. Output capacity: DC 5V to 36V, at room temperature, continuous current 15A, power 400W. If enhance heat dissipation is used the switching current can be increased up to 30A.
4. Quiescent Current: 20mA.
5. Operating Current: 50mA.
6. Working temperature: -40 to 85 °.
7. Size: 6.0 x 3.4 x 1.2cm.
8. Output MOS devices are isolated from the rest of the circuit using optocouplers.
9. Additional filtering for enhanced anti-jamming capability.
10. Industrial grade board.

Caution:

1. The output voltage is equal to the input voltage.
2. The ' DC + ' and ' Load + ' terminals are connected together on-board. The module controls the load by switching the ' Load - ' to ' DC- '. These two connections cannot be shorted external to the board, otherwise the load can not be controlled.

Timing range

0.1 seconds (min) to 999 minutes (max) continuously adjustable

Selecting the timing range.

After setting the mode selection screen parameter value by a short press "STOP" button to select the time range;

XXX. decimal point in the unit place, time range: 1 second to 999 seconds.

1. X decimal point in decade place, Timing range: 0.1 seconds to 99.9 seconds.
2. X. X. decimal full brightness, Timing range: 1 minute to 999 minutes.

For example, you want to set "OP" is 3.2 seconds, then move the decimal point to decade place, the digital display 03.2

Parameter description: "OP" - conduction time, "CL" - off time, "LOP" - the number of cycles (1-999 times, "---" represents infinite loop).

These parameters are independent of each other, but is shared by each mode. For example, in P1.1 mode, set the on-time "OP" is 5 seconds, if you switch to P1.2 mode, it's "OP" will be 5 seconds too.

In the main interface (display 000), short press "SET" button will display "OP" ( "CL", "LOP") and the corresponding time XXX.

Some parameters only mode "OP" (such as the mode P1.1, P1.2, P1.3), short press the "SET" key to display only the “OP” and the corresponding time.

Some models have parameters "OP", "CL", "LOP" (such as the mode P3.1, P3.2), short press "SET" button will display "OP" and the corresponding time, “CL” and the corresponding time, “LOP” and the corresponding number of times,

In the main interface by short press "SET" key to see information about the parameters of the current mode.

Setting the parameters.

1. First, read the instructions to determine the required operating mode.
2. The module is powered up, the display at the current work mode (P1.1 default mode), then enter the main interface; press "SET" button for 2 seconds after release to enter mode selection interface; a short time by pressing "UP", "DOWN" key to select the mode (P1.1 ~ P-4).
3. Select the mode (such as P3.2), short press the "SET" button, then the parameter to be set flashes ( "OP" on-time, "CL" off time, "LOP" cycles ( "---" represents infinite loop)), by "UP", "DOWN" keys to adjust the parameter value, support long press (rapid increase or decrease) and short press (increase or decrease one unit); then short press the "STOP" key to select the decimal point position, select the time range (0.1 seconds to 999 minutes); short press the "SET" button to set the next parameters of the current mode of procedure is as above.
4. After the parameters are set, long press "SET" button for 2 seconds then release, the name of the current mode will flash once, and then return to the main screen, set the parameters of success!

The main interface: In the relay does not work status display "000" (no decimal point), with a decimal point under relay state.

Mode selection screen: Long press the "SET" key to enter, after setting is completed, long press the "SET" key to exit back to the main screen.

"STOP" button extensions:

Relays enable mode:

1. ON: Relay allows conduction in the "OP" on-time.
2. OFF: relay prohibit conduction is always closed.

In the main interface, short press the "STOP" button to switch between ON and OFF, the current in which the state will flash, and then return to the main screen. (This feature is an emergency stop function, click off the relay)

Sleep mode:

1. "C-P" Sleep mode: five minutes without any operation, the digital display automatically turns off, the program running as usual.
2. "O-d" normal mode: digital display always open.

Press the "STOP" button for two seconds and then release to switch "C-P" and "O-d" state, in which the current state of flashes and then return to the main screen.
