Timer PCB: The Ultimate FAQ Guide
Every piece of electronics holds a printed circuit board. A timer is a complex electronic device. However, timer PCB is also a complex type of PCB that you will find.
The timing mechanism is a piece of electronics. Proper engineering is required to function timer PCB boards.
However, with a complex piece of art, you may have a shortage of information. You may have raised questions in your mind about timer PCB and its mechanism.
We will try to fulfill your interest in knowing about timer PCBs by answering several most related questions.
What Is Timer PCB?
When an electrical switch is activated, a timer, also known as a time switch or timer switch, is used to control the switch. A timer is a device that activates electrical switches via the use of a timing mechanism.
The timer was first used in 1945. Windows, electric signs, apartment hall illumination, oil and gas burners, and stokers were all examples of where it was used.
Timers are used in different embedded systems to keep records of different events. They maintain the operational times of embedded systems by collaborating with clocks. The clock might be external, or the clock in the embedded systems.
Essentially, the timer is powered by a printed circuit board. The timer PCB is the circuit board that provides electricity to the timer switches.
To put it simply, the timer employs timer relay PCBs to set the times on the clock. When a certain time is required, relay time is employed. The relay timer may be programmed to run at a certain time. The relay remains turned off till the time is up.
A DIL switch may be used to configure the timer relay PCB. The relay timer has three operating modes: Delay ON, Delay Off, and Pulse. Delay ON is the default mode.
The timer, on the other hand, works by connecting the switches to an electric power source. Additionally, they may be powered by low-voltage batteries that can be located in various places.
What Are The Types Of Timer?
However, there are two main categories of timer PCBs. They are Digital timer PCB and Analog timer PCB.
Digital Timer PCB
With digital inputs, you may control and alter the digital timers in real-time. In addition, digital consoles and scales with digital timer PCBs may be used to examine the output.
Digital Monofunctional Timer PCB
To set both the timer and the starting point of the timer, you must use distinct buttons. LCDs are used to show the states of the timer.
The analog timer is the opposite of a digital timer. You will have an available knob to control and set the timer. Also, you can observe the output in analog scales. You can easily adjust the timer by using the knob mounted on the front panel of the timer.
What Are The Operating Modes Of Timer PCBs?
There are four basic types of operational modes used in a timer. They are On-Delay operation, Off-Delay operation, Flicker operation, and Interval Operation.
However, On-Delay and off-Delay are the most basic types of operations.
When using the On-Delay mode of operation, there are certain time delays between the timer’s input signal being received and being processed. The procedure is referred to as an On-delay operation because it occurs at a later time.
After a certain interval, the timer in on-delay counts the output of the timer and displays the results of the count. One exception is that only automated timer devices use On-delay actions.
By looking at its name, it is clear that the Off-Delay is understood. Off-delay operation begins as soon as the timer begins to receive inputs, if at all feasible. As soon as the timer’s output reaches the end of its defined duration, the timer is turned off.
The timer, on the other hand, may compute the set time of the timer after the set time is turned off. An example of an Off-delay function is a security door light, which may be found in many offices.
What Is 555 Timer PCB IC?
The 555 timer is a clock generator that employs a PCB with 555 timers on it. It’s a 555 timer PCB layout with a digital monolithic IC placed on it.
To put it another way, the 555 timer IC is a timing circuit with a 555 timer circuit PCB layout. A 555 timer can provide almost error-free timing signals. It employs a duty cycle of fifty percent or a hundred percent to create timing pulses.
555 timer PCB circuits are used to provide monostable and astable timing. 555 timers may have delays ranging from microseconds to hours.
555 Timer PCB Board IC
Because of its low cost, the 555 Timer is one of the most common timer PCB ICs. It can work with a DC voltage range of 4.5 to 15 volts. The most important feature is that the different voltage types do not affect the timer’s output.
The 555 timer is one of the most dependable linear compatible timers available. Transistor to Transistor Logic (TTL) and CMOS may be directly coupled.
The 555 timer circuit PCB Layout is much too simplistic. It’s a common component in electronics projects. An 8-pin 555 IC is also made up of 2 diodes, 15 resistors, and 25 transistors.
What Are The Different Uses Of 8 Different Pins Of 555 Timer PCB IC?
Let’s check the different functions of the 555 timer PCB IC’s different pins.
555 Timer IC Pins
The ground pin connects with the ground plane of the PCB. It ensures the grounding of the IC. This pin is either connected with the ground plane or to the negative rail in special cases.
The trigger pin is the input trigger of the 555 timer IC that activates the timing cycle of the timer. The trigger uses a low signal to trigger up. When the trigger gets one-third of the supplied voltage, then it goes high from the low voltage.
Output pins allow the timer to generate the output of the timer and then connect to the output terminal of the timer. The value of the output pin may be both low and high based on the timing cycle duration.
The reset pin is simply used to reset the timer. The voltage used for resetting the timer is 0.7V, whereas the required current is 0.1mA.
5. Control Voltage
The voltage pin carries two-thirds of the positive voltage. Between the voltage control and the ground region, there is a capacitor.
6. Threshold Voltage
One of the two inputs of a comparator circuit is the threshold voltage. It compares the voltage to the control voltage that is provided. The output voltage would be high if the threshold voltage was lower than the control voltage.
The discharge pin is responsible for providing a channel for the timing capacitor. It does this via the use of an NPN transistor. During periods of high voltage, the discharge pin behaves as an open circuit.
8. +VCC (Supply Voltage Terminal)
The timer’s primary voltage is represented by this value. The 555 timer IC requires a supply voltage to function effectively. This pin is linked to the positive rail of the power supply. The voltages vary from +5V to +18V in this circuit.
The following is a brief video explanation of 555 timer IC.
What Are The Types Of 555 Timers?
There are three types and working modes of the 555 timer IC available. Theta er as follows.
Astable mode is a mode that is not stable. In this case, the output of the 555 timer PCB is not steady. Rather, the production increases, and at times it decreases. None of this occurs as a result of the application of any external trigger.
In essence, no external trigger pulse is necessary while operating in Astable mode. You will see that the trigger pin and the threshold pins are linked together in Astable operating mode.
555 Timer Astable Mode Diagram
In the monostable mode, the user setup is a mashup of several settings. Modes that are both stable and unstable are combined. A high stable state value will result in a high final outcome if the stable state is set to a high value.
In the monostable mode, Vcc maintains the high level of the trigger input via the resistor on the timer PCB.
Both output states of the 555 timer PCB are stable in the Bi-stable mode. If there is an interruption, the output will be low-to-high and high-to-low. The previous output will continue until there is another interruption.
The trigger and reset pins are linked to Vcc via two resistors in the Bi-Stable configuration.
What Are The Applications Of Timer PCB?
The timer PCB may be found in a wide range of electrical devices. 555 timers, in particular, are widely employed in traffic light circuits, LED circuit dice, metal detectors, LED flashing circuits, and other applications. 555 timers are also used in joysticks, gaming paddles, and clap switch activators.

- Pack your boards in moisture barrier bags. Use desiccant to absorb any moisture sustained.
- Take care of the boards properly. Ensure the proper storing environment. Keep the storing area dust-free. Ensure a weather-proof environment for the storing rooms.
How To Test Timer PCBs During Manufacturing?
PCB testing is an important phase in PCB manufacturing. Testing detects if any fault happens or any requirement does not meet. Also, testing ensures the required quality of the timer PCBs.
There are many testing methods available to test the PCBs. You can use them as per your needs.
In-Circuit Testing (ICT)
ICT is the most common type of PCB testing method. It actuates individual circuits in the PCB. ICT is designed to test the entire PCB at a time. However, it can cover 90% of the PCB most of the time.
Fixed probes test the solder integrity, circuit connections, etc. Every component and circuit goes through an inspection.
Automated Optical Inspection
AOI uses two 3D cameras or a single 2D camera. The cameras take photos of every detail of the board. Then the photos are compared to the schematic of the timer PCB. If any fault is found, a technician takes the responsibility to fix them.
An X-ray can detect any tiny faults in the PCBs. Solder connection, internal traces, barrel are among the list that X-ray inspects.
X-Ray Inspection Of PCB Helps To Find Out Tiny Problems
In the functional test, the PCBs are used like end-use. You need to use the PCB in real applications so that you can check all defined requirements work perfectly.
