DC 3V-15V delay timer timing switch module 1sec~20hours1500mA for relay switc VG:
No output power, the output trigger only. (Positive control off).
1. After the power, Vo output terminal has no output, Vi-ended input trigger high-level signal, Vo output-side output high, the delay period of time, Vo output terminal has no output. Or: After power, Vo output terminal high level. Vi-ended input triggered high-level signal, Vo output terminal has no output, after a period of delay, Vo output terminal high level. More than two kinds of modes can be selected via a jumper on the module free.
2. The delay time adjustment range of about 1 second to 20 hours;
3.Vo output of low output drive capability of up to 1500mA (short time allowed 2500mA).
4. Power supply voltage: DC 3V-15V
5. The maximum operating current module:
At43: 3V ---- 0.7mA
5V ---- 1.3mA
12V ---- 3.6mA ;
The longer execution time, power consumption is smaller.
Note:When using the module, load the negative power supply is negative, the positive connection module Vo end load. That is the positive control of the load off.
Internal module with protection diodes and power supply decoupling capacitors, can be directly connected to an inductive load such as a relay, no longer parallel diode of the coil.
This module not only small, large timing range, but with a time proportion jumper timing applications for a long time, do not consume a lot of time in the adjustment process.
Purpose: delay switch, timer.
1. The delay time can pass on module comes with adjustment potentiometer, ranging from about 1 second to 20 hours, see below explanation.
2.Vo Output level can be set by a jumper, see below explanation.
1,2,3 three-pin used to set the timing range, 1-2 communicating timing of 1S-290S adjustable; 2-3 connectivity, timing expand 256 times for 256 seconds -20.5 hours adjustable.
4,5,6 three-pin state is used to set the module's output terminals Vo, 4-5 connectivity, no output power on the initial state, after the trigger has an output, no output after timing; 5-6 connectivity, power-on initial state there is output, no output after the trigger, regular time to recover after output.
Counterclockwise adjustment potentiometer, time is reduced, clockwise adjustment potentiometer time increases.
Timing range jumper in the timing of two locations for the 256: 1 relationship. Suppose need eight hours delay, you can use the jumper to 1-2 communicating, the delay time was adjusted to 8/256 = 0.03125 (h) = 112.5 (seconds), and then the two-pin jumper to 2-3 communicating it. This greatly shortens the debugging time. Debugging process requires self stopwatch.
Size: Free of pin size 15mm × 11mm × 8mm. Pin pitch 2.54mm.
1. The above parameters were measured at 5V, may be slightly different at other voltages;
2. Non-precision circuit requiring high NA and important occasions.
Vi: trigger signal input (high level trigger);
Gnd: Power Ground
