What are the best tips for relay connection?
relays are electronic switches used to power accessories or electrical system in vehicles. The relay can be an integrated perimeter in solid state, without moving parts, but also in the 21st century. There are many reliable, cheap mechanical switches. They provide power to many systems without having to install cumbersome wiring in the entire vehicle, which reduces costs and weight. Connection of the relay can be improved by selecting the good places that place them, and by providing the corresponding cabling size for powering the necessary accessories.
A typical relay looks like a small box, maybe 1 inch (2.5 cm) on each side, with four connectors or pins on the bottom. The relay connection is often installed in the wiring blocks, where the staff plugs are connected to sockets that correspond to the shapes of the pins, and the wires are connected from the sockets to the vehicle systems. This allows you to easily replace the part if it disconnects and connects the new one.
Four pins on the bottom of relays are often Numa each is connected to anotherat the wire. One connects to the ground of the vehicle that returns any unused power to the battery. One pin is connected to the switch, such as the ignition key that activates the relay. The other two are connection to the battery and from relay to systems or accessories for vehicles.
When the driver turns the key to start a car or truck, a signal is sent from the ignition switch, but the cabling can be quite thin. This is possible because the main power relay, which supplies the entire vehicle by power, is located in the engine compartment near the battery. The battery wire to the relay can be relatively strong to supply all electrical needs, but the wire from the ignition key can be thin, as its only purpose is to supply a small electric current. When the key is turned, the current activates the switch inside the relay and the power supply from the battery flows to the vehicle through the relay connection.
Installation of relay connection is not difficult, but some tips can helpor easier to make a job. The location is important, so the heavier wiring lengths are kept to a minimum, both to save money and to reduce energy loss. The wire collected from the positive battery terminal should be connected directly to the relay pin and others to the accessories using the shortest length of the required wire. This may place a relay closer to the battery or accessories depending on the vehicle.
The switch that controls the relay can be installed anywhere on the vehicle, with cabling supplied from an existing power supply or other power supply of accessories. Power supply requirements for activation switch are small, so smaller wire sizes can be used and located in the vehicle as needed to hide them. The use of a relay block for installing multiple units can facilitate the role of their connection separately.
Relay connection is useful for further lighting, louder corners Tklobouk require additional power or navigation systems. The use of a separate relay allows these systems to beoperated separately from the vehicle ignition system. This reduces the power load on the ignition system and can reduce electrical problems.
