Time controller circuit diagram using CD4060

Published:2011/10/20 21:20:00 Author:Rebekka | Keyword: time controller

When the circuit gets power, it is connected instantaneously, and R5, C3 constitutes the differentiating circuit to guarantee delay time from zero. Under oscillator signal's influence, CD4060's internal counter starts to work, 3 feet is the 14th level counter's out port, if it makes 3 feet switches to the high level from low level, it needs t=213×2.2KC (second), and the low voltage of pin 3 causes the triode V closure. When delay time reaches, pin 3 jumps to high level from low level, then V is saturated breakover after being current limited by R6, and relay K pulls in, then the load gets the electricity. This electric circuit's delay time can be adjusted in 2.1~4 hours.   (View)

Electric single-girder crane radio remote control(TX315B1) circuit diagram

Published:2011/10/19 20:47:00 Author:Rebekka | Keyword: Electric single-girder crane , radio remote control

Four operation functions of the circuit: Mobile electric hoist travel hook (hanging objects) can do up and down movements. The right half part of the dotted line in the figureis the operation of cranes in the original circuit. K1 ~ K4 are the original manual operation buttons. Now they are used to replace the relay contacts, SQ is the improving limiting switch. KM1 ~ KM4 are the AC relays that are used to control the motor to enhance the motor M1 and M2. It controls and rises the forewardandreversal rotation of hanging objects. The dotted lines ofleft halfpart inthe figure form the new radio remote control circuit. In the circuit, the four output ends A ~ D of TX315B1 receiving circuit canrespectively drive tubes VT ~ VT4.   (View)

Multi-channel wireless remote control circuit(F36-F／F36-J)

Published:2011/10/19 22:34:00 Author:Rebekka | Keyword: Multi-channel, wireless remote control

Remote control transmitter circuit. Receiver decoding circuit. The circuit is composedof F36-F/F36-J multi-channel radio remote control circuit. In the transmitter circuit, it usesDTMF encoding and decoding circuit to turn launch four-key input signal into a binary code inputand sent out by F36-F . In the receiver circuit, F36-J will receive the remote signal and pass demodulation decoding and reduce to four binary code. Four binary code passes a four - sixteen line decoder and turn to a four - sixteen line decoder. It controls a corresponding circuit.   (View)

Wireless remote control plus and minus resistor network circuit diagram

Published:2011/10/19 22:15:00 Author:Rebekka | Keyword: Wireless remote control plus , minus resistor network

Transmitter circuit is shown in figure 1. CD40193 is a dual clock synchronous 4-bit binary up / down counter, andits function is shown as the table. CPU is the addition clock impulse input terminal, and CPD is a subtraction input of the clock pulse. When it inputs 0 to 15 pulses, its output terminals Q3 ~ Q0 change with the oder of 0000 ~ 1111 (addition) or 1111 ~ 0000 (subtraction). It is fired by the built-in antenna outside. CD4011 NAND chip is composed of two ultra-low frequency oscillators. The other two NAND gatesare the addition and subtraction counting gate. When the subtraction S1 door is open, CD40193 reduces the count. When the addition count door S2 is open, CD40193 starts the additional counts. The working voltage of CD4011 and CD40193 is 5V. Ultra-low frequency oscillator frequency is about 0.5 ~ 2Hz.   (View)
