Engine Relay Board Hookup Guide. As gear like engines and relays need high present, microcontrollers cannot drive them.

Engine Relay Board Hookup Guide. As gear like engines and relays need high present, microcontrollers cannot drive them.

so that you can drive them, we are in need of unique drivers that are current. Motor relay board comes to the photo as a result of these demands. Motor relay board drives motors and relays by providing adequate present. It may drive one relay and four DC engines or one motor that is stepper a time. The engine relay board eases the duty of interfacing outside engine and AC products because of the ATmega32 microcontroller. This has ULN2003 motorists for high applications that are current motor driving and relay driving circuits for AC unit interfacing.

You will find three primary parts for an engine relay board.

Relay Motorist

Making use of the supplied relay circuit, 230V products may be managed. This area is useful for automating the on / off.

Engine Driver

The DC engine could be managed by using this area, there was 4 driver that is ULN2003 lines for driving engines and every provides enough present to regulate the DC engine.

Exterior Interfaces

* Terminal block (3pin) –for linking relay IN and OUT * Terminal block(7pin) – for linking 4 lines of engine, 1 for energy and 2 pins for ground

Linking the Board

* switch on the board SW1 that is using LED will glow. * Connect the slot connector to your standard slot. * Shunt the jumpers in J4. * Use jumper caps to pick pins that are port. First four pins (0, 1, 2&3) are relay selectors. The relay is attached to 4 pins. * Use port pins 4,5,6&7 for engines in the region of motor D, C, B&A. * Set the input slot pin correspondingly to show ON/OFF the relay/motor.

Procedure

There is certainly a header that is alternate for accessing specific pins.

The Jumper description can be below for J4.

The motor and relay inputs are straight accessed because of the header J5.

Terminal Obstructs

Terminal obstructs can be used for linking engine, outside supply, and relay equipment that is controlled.

There are three blocks that are terminal.
