Relay Module Wiring Diagram

The six pins on the left side of the relay module connect high voltage and the pins on the right side connect the component that requires low voltage.

Relay module wiring diagram. Wiring diagram is shown in the figure given below. The relays are energized with low inputs to the in1 in2 in3 and in4 inputs. Wiring diagram for 2 relay module interfacing with arduino is shown in the figure given below. Now i assume the jumpers allows the relay module to take power from the vcc of the main pin block.

With solid state relays ssr there are no contacts and switching is totally electronic. Learn arduino in 30 minutes video. From your controller eg arduino or raspberry pi connect ground 0v to the relay module s gnd and power to the module s vcc. Optocoupler is a component that transfers electrical signals between two state of isolation circuits by using light and prevent high voltage from affecting the system receiving the signal.

In electromechanical relays emr contacts are opened or closed by a magnetic force. Variety of 12 volt solenoid wiring diagram. Relays are either electromechanical relays or solid state relays. 5v 1 channel relay module.

There are four relays that each provide dry contact outputs. The real benefit behind a relay is more than automation. On that page it has a wiring diagram the pins are hard to see in the pic the main block is gnd in1 in2 in3 in4 in5 in6 in7 in8 vcc the smaller block with the jumper is gnd vcc jd vcc. 5v 2 channel relay module.

5v 8 channel relay module. The decision to use electromechanical or solid state relays depends on an application s electrical requirements cost constraints and life expectancy. The module is supplied with power via the pin labeled vcc and ground via the pin labeled gnd. In most arduinos the power will be 5v in a raspberry pi it will be 3 3v but these relay modules will work ok with 3 3v even though they are officially rated at 5v.

To ensure that the switch contacts are in their correct state modules must be made to communicate with the panel before connecting circuits controlled by the module. Car qook automotive dc 12v 12 volt 30a amp spdt wiring power relay. The following figure shows the relay module pinout. Get a relay module.

Relay module wiring diagram. 12 volt relay wiring schematic. With the vcc and jd vcc jumpered. The purpose of a relay is to automate this power to switch electrical circuits on and off at particular times.

All relay switch contacts are shipped as shown in figure 3 but may have transferred during shipping.
