Description Single Channel 12V Relay Board: A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The board has ONE relay which works on 12V but the input signal can come directly from microcontroller output working at 3V or 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by the RED Led. This is a Single channel relay board operates on 12V. Can be used directly to control 240V power appliance from most of the microcontrollers and other control system circuits. Perfect for switching 240V appliances like lights, fans, etc. The board has a high quality relay, which can handle a maximum of 10A @ 120V or 7A @ 240V AC. Each Relay has three connections - Common - C, Normally Open-NO, Normally Closed-NC brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board. Features: Selectable Port Input Mounting Supports Provided Relay Switching Output Suitable for 7A @ 250Vac or 10A @ 120Vac LED Indication of Relay ON. Power Indication LED. Direct input from 3-5V Microcontroller for relay control. Output terminal for relay contacts. Provision of male header for wire connection. Powered from external 12V or from male header.

4 x ULN High Current Darlington Array ICs Plus 4 x 16 Pin IC Base... *** MUST HAVE FOR STUDENTS  AND HOBBYIST ***  The ULN is a monolithic IC consists of seven NPN darlington transistor pairs with high voltage  and current capability. It is commonly used for applications such as relay drivers, motor,  display drivers, led lamp drivers, logic buffers, line drivers, hammer drivers and other  high voltage current applications. It consists of common cathode clamp diodes for each  NPN darlington pair which makes this driver IC useful for switching inductive loads. The output of the driver is open collector and the collector current rating of each darlington pair is 500mA.  Darlington pairs may be paralleled if higher current is required. The driver IC also consists of a 2.7KΩ  base resistor for each darlington pair. Thus each darlington pair can be operated directly with  TTL or 5V CMOS devices. This driver IC can be used for high voltage applications up to 50V. Note that the driver provides open collector output, so it can only sink current, cannot source.  Thus when a 5V is given to 1B terminal, 1C terminal will be connected to ground via darlington  pair and the maximum current that it can handle is 500A. From the above logic diagram  we can see that cathode of protection diodes are shorted to 9th pin called COM.  So for driving inductive loads, it must connected to the supply voltage. ULN is widely used

High current darlington array: containing seven open collector darlington pairs with common emitters. Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. Useful for driving a wide range of loads including Solenoids, Relays DC Motors, LED Displays & Filament Lamps. 600mA Peak Output Current 50V Output Voltage The ULN is a monolithic IC consists of seven NPN darlington transistor pairs with high voltage  and current capability.

It consists of common cathode clamp diodes for each  NPN darlington pair which makes this driver IC useful for switching inductive loads. The output of the driver is open collector and the collector current rating of each darlington pair is 500mA.  Darlington pairs may be paralleled if higher current is required. The driver IC also consists of a 2.7KΩ  base resistor for each darlington pair. Thus each darlington pair can be operated directly with  TTL or 5V CMOS devices. This driver IC can be used for high voltage applications up to 50V. Note that the driver provides open collector output, so it can only sink current, cannot source.  Thus when a 5V is given to 1B terminal, 1C terminal will be connected to ground via darlington  pair and the maximum current that it can handle is 500A. From the above logic diagram  we can see that cathode of protection diodes are shorted to 9th pin called COM.  So for driving inductive loads, it must connected to the supply voltage. ULN is widely used

Description L298N is a kind of high voltage, high current motor driver chip produced by ST company. Having 15 pins as package, this chip has such features as high working voltage(maximum voltage up to 46V), large output current(instantaneous peak current up to 3A, continuous working current 2A) and 25W of rated power. Two built-in H birdge high voltage and large current full bridge drivers can be used to drive the DC motor and stepper motor, relay coil and so on. Using standard logic level signal control, it has two enable control ends. It permits or prohibites device having a logic power supply input without the impact of input signal,which enables the internal logic circuit part works at low voltage. The chip can connects to external detecting resistor to give the variations to the control circuit. Using L298N chip to drive the motor, this chip can drive a stepping motor or four phase stepping motor, and two DC motors as well. Features： Using L298N made by ST company as the control chip,the module has such characteristics as strong driving  ability, low calorific value and strong anti-interference ability. This module can use built-in 78M05 for electric work via a driving power supply part.But to avoid the damage  of the voltage stabilizing chip,please use an external 5V logic supply when using more than 12V driving voltage. Using large capacity filter capacitor,this module can follow current to protect diodes,and improve the reliability Specification Double H bridge drive Chip L298N (ST NEW) Logical voltage 5V Drive voltage 5V-35V Logical current 0mA-36mA Drive current 2A(MAX single bridge) Storage temperature -20 to +135 Max power 25W Weight 30g Size:mm Applied cases: 1) Driving stepper motor The connection of driving a common 4 line 2 phase electric motor is shown
