6~60s high precision timer

Published:2011/4/20 22:10:00 Author:Nicole | Keyword: 6~60s timer

6~60s high precision timer. The timing time range of this circuit is 6~60s. When turning on switch AN, relay J1 pull-in, capacitance C1 is changed by R1 and potentiometer KP. When the voltage on C1 reaches 2/3 of power supply, IC output state is reversed, to complete the timing process. The function of voltage stabilizing diode VW2: when power voltage changes, it can keep the voltage steady; VW1 is used to stabilize the capacitance charging voltage, it can improve the precision. The timing time of circuit is T＝1.1(R1+KP)C1, to adjust KP will obtain any timing time between 6~60s. Voltage stabilizing diode VW1 can use 8V、1/2W,VW2 6V、1/2W.   (View)

Half four-bit LED counting circuit

Published:2011/4/21 21:42:00 Author:Nicole | Keyword: LED counting

It is a CMOS half four-bit decimal counter, it has counting, latching, bit by bit scanning output circuit, protection circuit. The scanning speed can be changeable, it only needs to change a external capacitor. The power supply is 3~10V, the static power consumption is lower than 1mA, the counting frequency range is from DC to few MHz, it adopts DIP-16 foot in-line package. The count pulse is coupled to input DG6010 count by high speed photodiode isolator SL950. 6010 sends out BCD code then transformed 7 phase drive singal by CC4511B, the singal is added to 4 bit LED to display. This counting circuit is used as faceplate counting for all kinds of instruments, such as range counting, product counting, flux counting, timing and so on.   (View)
