Multifunction 2s - 1000h Delay Timer
Shape about 12mm * 12mm, operating voltage 2v-5v,timing can be set to a minimum to a maximum of 2 seconds 1,000 hours, as indicated below description
Function and Design
1. The circuit according to claim conted and set a good time resistance and supply voltage;
2. Before the power not trigger output is high;
3. Trigger terminal "falling" trigger effective immediately
4. Set the timer time to recover after the output terminal is high, wait for the next "falling" trigger;
5. The chip is not repeated triggered, meaning that
6. The trigger end of "falling" Trigger refers to the instantaneous change from high level to a low level;
7. General refers to VCC high voltage, low means 0-0.3v or GND,
8. trigger terminal can be conted to touch switch or microcontroller IO port or
9. The trigger can be designed to power, only to trigger a short circuit to ground, power is triggered,
Falling edge trigger again.
Chip Features:
1. The use of low-power CMOS technology, lead-free and environmentally friendly.
2. Direct Push can output low LED
3. Available resistance adjusting timing, there are 8 * N (N = 0.1.2.3) times the timing selection,
time can be adjusted from 2s-1000h.
4. Optional trigger timing and triggering termination ground electric timer.
5. standby output high, falling edge trigger, post-trigger output low, after the delay recovery high.
Digital Timer C005 is a trigger module with a duration of 2 seconds to 2 hours with a power supply of 5V. The module works in a very simple way, after applying a low GND signal to the trigger input pin, a low GND signal is fed to the output pin. The signal is present as long as the timer does not count down the time to the end, and the time is set by selecting the appropriate value of the RT resistor. There are also 2 configuration jumpers P1 and P2 in the module, jumpers act as multipliers of the time set by the resistor. P1 multiplies the set time x10 and P2 x100.
