Configurable time switch, suitable for periodically turning on ventilation, heating, LED lighting, headlights, micro-pumps, solenoid valves, DC motors and other DC powered devices.
that the output is not made in the form of closing relay contacts, but in the form of field-effect MOSFET transistors connected in parallel and operating in a key mode. When the relay is triggered, the transistors open and pass the module supply voltage to the output. The maximum current is up to 15 A, the maximum rated switching power is 400 W.
It is possible to set it up for operation from an external trigger.
Has an LED indicator for displaying the current time report, operating mode and settings.

Dimensions: 60x35x12
Features and benefits:
-
Fast switching of the output state.
-
State switching does not produce any electromagnetic interference, noise or sparks unlike conventional relays.

Relay programming instructions:
The relay has several modes, the relay can only work in one of the modes, to change the mode, you need to hold down the button SET for 1 second and release,
now using the buttons UP (top) and DOWN (bottom) we select the required mode and confirm the selection by short pressing the button SET.
The list of modes and their purpose is described below:
P1.1 - In this mode, the relay is by default open, when a logical units (from 3V to 24V) per port Trigger the relay immediately closes and starts the countdown set in the parameter OP, after the countdown ends - the relay turns off.
P1.2 - In this mode, the relay is also disabled by default, when a signal is applied to the Trigger port, the relay closes and the countdown specified in the parameter begins OP, after the end of the countdown, the relay is disabled as in the mode P1.1, but before the time expires, we can start counting the time over again by signaling the port again Trigger.
P1.3 - In this mode, the relay is off by default, after the power is turned on Trigger is turned on relay and starts counting the time specified in the parameter OP. After the countdown, the relay will turn off in the previous mode, but we can also interrupt the timer and open the relay ahead of time if we reapply a signal to the port Trigger.
P-2 - this mode is triggered when a logic signal is applied to Trigger, executes once and waits for the next logical unit feed. When a logical unit is supplied, the time relay first waits for the time set for the open state CL, and after this time has elapsed, it closes the relay and waits for the time set for the closed state OP. Then it opens the relay again and waits for the next signal to Trigger, setting the number of repetitions is not available here.
P3.1 - this mode is similar to P-2 except for a few things, when when a logical unit is supplied to the port Trigger, the relay goes directly to the closed state and not to the open one, you can also specify the number of repetitions in this mode LOP. If after the relay is triggered by a signal on Trigger the relay starts to work and without completing all the cycles we send a signal to the port Trigger

______________
SET
In these settings, we can change three functions:
OP - The time the relay is in the closed state
CL - The time the relay is in the open state
LOP - The number of repetitions (cycles) on/off the relay
To set the values of each of the functions, you need to select one of them by pressing the button SET after which it will light up, blink 3 times, and then you can set its values ... If you need another function, just press the button SET again, in other words the button SET is now scrolling through these 3 functions. After we have selected the desired function, we have three numbers, with which we can configure our function according to the instructions below:
OP function (closed state):
Needed in order to set the time during which our relay will be closed.
Now we have three digits on the display, this is the operating time of our relay, if we press the buttons UP and DOWN, then we can change it to a larger one or the smaller side.
As you may have noticed, in addition to the numbers, we also display the bit point.
If this point is only after the third digit, then we set the time in seconds.
If the dot is after the second digit, then we set the time in 0.1 seconds (tenths of milliseconds)
If we have 3 dots, then we set the time in minutes.
In order to change the position of points, you need to shortly press the button STOP After setting the required time, go to the setting of the next function by short pressing the button SET, or save the mode setting by long pressing the button SET.
CL function (open state):
Configurable precisely as well as function OP. Only here we set the time during which our relay will be in the open state.
In the same way, the display shows 3 digits, which, depending on the location of the point, can mean seconds, 0.1 seconds and minutes. In the same way, with the button STOP we change the location of the point.
LOP function (number of repetitions):
And finally, the last function is responsible for the number of repetitions of open and closed cycles relay status. Here we can only specify the number of repetitions from 1 to 999 using the buttons UP and DOWN, if we want the cycles to repeat indefinitely, then it is necessary to set a value less than 1, then the display will show - - (3 dashes)
After you have set the time for the open and closed state of the relay, as well as the number of repetitions, you can save the settings by long pressing (2-3 sec) the button SET, after Releasing the button SET the display will flash the selected mode 3 times.
It remains only to start the operation of the relay by pressing the button STOP, while the screen will display the inscription ON, another press of the button STOP will turn off the operation of the relay, while the display will show OFF.
