Wide voltage 5V-30V trigger delay relay module timer module delay switch Wide voltage 5V-30V trigger delay relay module timer module delay on delay switch
Module highlights:
The time can be adjusted by the potentiometer to meet your most occasions. With MicroUSB 5.0V power input, it is very convenient to use. 5--30V power supply voltage. External trigger and on-board key trigger. With relay pull-in indicator. Strong anti-interference ability, the relay will not malfunction under various interference, suitable for industrial control.
Module characteristics:
1. Working voltage: any voltage between 5-30V wide, MicroUSB and welding terminal power supply interface 2. Working mode: After supplying power to the module, the state of the output terminal of the module is: normally open (NO) is disconnected from the common terminal (COM), and normally closed (NC) is connected with the common terminal (COM). Give a low-pulse signal at the external trigger terminal (TRIG) or touch the trigger button, the relay sucks and the work indicator lights up. At this time, the status of the relay output terminal is: normally open (NO) and the common terminal (COM) are conducting, The normally closed (NC) is disconnected from the common terminal (COM). After 0-24 seconds (this time can be adjusted according to your needs), the relay is disconnected, and the relay returns to the state before triggering. 3. The time can be adjusted by the potentiometer. The default is 0-24 seconds. If it takes longer, you can replace the larger capacitor (C2) or potentiometer by yourself. Delay time formula: T = 1.1RC. For example: if the capacitance is 22uf and the resistance is 1M, then T = 1.1 * 0.000022 * 1000000 = 24.2 seconds. 4. With relay pull-in indicator. 5. The module can control: 10A 250VAC (AC), 10A 30VDC (DC) load. 6. With relay continuous current protection. 7. The signal end of the module is designed with a pull-up and filter circuit, which has strong anti-interference ability and is suitable for industrial control. Many manufacturers have added optocouplers for isolation, but the module is not isolated from the ground of the trigger signal, which does not provide anti-interference effect. After testing, it is found that the stability of the trigger terminal can be improved to resist interference. No matter the module is in an electromagnetic interference environment or when the module is powered on and off, the relay will not malfunction. 8. Size: 5.4 * 1.9 * 1.8cm (length * width * height) 9. Weight: 16g
Applications:
1. Anti-theft alarm delay, building sound and light control light switch, etc. 2. On-time delay of on-board equipment prevents excessive current from burning the vehicle equipment when the vehicle is on fire. 3. Sequential start-up is required to prevent multiple devices from starting at the same time when the current is too large to burn down the appliance.

A bidirectional logic level translator is a small device that safely steps down a 5V signal to 3.3V while boosting 3.3V to 5V. This level shifter is also available for 2.8V and 1.8V devices. What sets this logic level translator apart from our previous versions is that you can successfully set high and low voltages and safely raise and lower them on the same channel. Each level shifter has the ability to convert 4 pins on the high side to 4 pins on the low side, with two inputs and two outputs for each side
Level shifters are very easy to use. The board needs to be powered by the two voltage sources (high voltage and low voltage) used by the system. High voltage (eg 5V) to "HV" pin, low voltage (eg 3.3V) to "LV", ground from system to "GND" pin
Compatible with 5-3V systems
VIN is connected to 5V system power supply
5A to 5V system
5B is connected to 5V system
GND connects to 5V system GND
3V3 connects to 3V system power supply

Introduction:
The module adopts XL4016 switch-type voltage regulator chip, cooperates with MBR10200 double rectification, and adds load protection circuit in the circuit to protect the load. The maximum instantaneous output current can reach 8A, and a fan is required to dissipate heat. It is recommended to be within 5A for long-term operation.
Main control chip used:
XL4016 is a switching step-down line DC-DC converter chip with a fixed switching frequency of 180KHz. The chip has excellent linear regulation and load regulation. The output voltage can be adjusted between 1.25V and 36V. The chip integrates reliability modules such as over-voltage protection, over-current protection, over-temperature protection, and short-circuit protection.
MBR Schottky diode is characterized by low forward voltage drop and high forward current. It can not only replace ordinary rectifier diodes for rectification circuits, but also replace fast recovery diodes for switching power supplies. In some cases, rectification is required. It is also suitable for occasions where the link loss voltage is low and the rectification is large.
LM358 operational amplifier
LM358 is a dual operational amplifier. There are two independent, high-gain, internal frequency-compensated operational amplifiers, which are suitable for single power supply with a wide range of power supply voltage, and also suitable for dual power supply mode. Under the recommended working conditions, the power supply current has nothing to do with the power supply voltage.
l Internal frequency compensation
l High DC voltage gain

CD4051 electronic switch
CD4051 is a single-channel digital control analog electronic switch, with three binary input terminals A, B, C and INH input, with low on-resistance and very low cut-off leakage current. The digital signal with amplitude of 4.5~20V can control the peak value to 20V analog signal. For example, if VDD= 5V, VSS=0, VEE=-13.5V, the digital signal of 0~5V can control the analog signal of -13.5~4.5V. These switching circuits have extremely low static power consumption in the entire VDD-VSS and VDD-VEE power supply range, regardless of the logic state of the control signal. When INH input terminal = "1", all channels are cut off. Three-bit binary signal selection channel One of the 8 channels can be connected to the input terminal to the output.
XL1509 overview:
XL1509 is a 150KHz fixed frequency pulse width modulation (buck type) DC/DC converter. It has 2A load drive capability and high efficiency, low ripple and excellent linearity, good load regulation ability, and only requires a minimum of external components. Adjustable output is easy to use, built-in frequency compensation and fixed frequency oscillator.
The pulse width modulation control circuit can linearly adjust the duty cycle from 0 to 100% . With enabling function, built-in over-current and short-circuit protection functions, when over-current and short-circuit protection occurs, the operating frequency of the XL1509 is reduced from 150KHz to 50KHz. The built-in frequency compensation module minimizes damage to the external components of the XL1509.
