It is an ideal board to control & switch high current loads like a fan, lights. I am measuring the battery consumption, tuning my circuits to be most efficient. This is a single channel relay board with one 24 volts high current relay. I am actually bothered by current draw, since this obviously runs on batteries. My problem is that I am confused by the AMP rating on a 12-volt relay, if its rated at 100 amps does that mean 50 amps at 24 volts ? I would use a buck converter or 7812 to regulate voltage down to 12 from 24, and simple mosfet transistors to toggle the coil on the large relay I need. But unless you've bothered to actually measure your current draw to know your wire needs, or if you think wire thickness needs are based on voltage, then you've got some learning to do yet. Non-negotiable.ĭon't worry so much about wire thicknesses, a lot of it is very overbuilt. If you have your batteries in 24V config, you need to use a 24V relay. The switching side can handle much much more as it's simply metal contacts connecting. Mornsun's K78 series is a high-efficiency switching regulator with the packages of SiP, SMD, or DFN.You need a relay that is rated both for voltage and current.īut you need to first understand what is meant by "12V automotive relay" as you say.

Omron's G8PM DC Automotive PCB Relay is a high load automotive relay for motor/resistive control. So, by a simple mechanism, controlled by 9V, we can control the AC supply of 230V. When the switch is closed, current start flowing through the coil, and by the concept of electromagnetic induction, magnetic field is generated in the coil which attracts the movable armature and the Com Port get connected with NC (Normally Close) pin of the relay. At the initial condition when switch is open, no current flow through coil, hence Common Port of relay is connected to NO (Normally Open) Pin, so the LAMP remain off. An ON/OFF switch is added for the switching purpose of the relay. In the above circuit, 5V relay is powered by a 9V battery. In this relay circuit we use a push button to trigger a 5V relay, which in turn, complete the second circuit and turn on the lamp. Next we will take a simple example where we will be turning on an AC lamp (CFL) by using a relay switch. So as of now we understand what is a relay and why they are used in the circuits. Generally a DC signal is used to control circuit which is driven by high voltage like controlling AC home appliances with DC signals from microcontrollers. It is mainly used to control a high powered circuit using a low power signal. The main operation of this device is to make or break contact with the help of a signal without any human involvement in order to switch it ON or OFF. So relay is a switch which controls (open and close) circuits electro-mechanically. Tutorial tentang relay start hino dutro 24 voltHINO TRUCKS/EQUIPMENT. Dictionary says that relay means the act of passing something from one thing to another, the same meaning can be applied to this device because the signal received from one side of the device controls the switching operation on the other side. 059 4 pin relay electrical switch 24v 24 volt th-r511 w-r511 r511 tail lamp light. Relay is an electro-mechanically operated switch, however other operating principles are also used in relays, such as solid-state relays. A Relay is generally used when it is required to control a circuit by a separate low-power signal, or when several circuits must be controlled by one signal. They are classified into many types, a standard and generally used relay is made up of electromagnets which in general used as a switch. Let’s see how this electromagnet acts as a switch and why it is named as RELAY. Later this was improvised and used in various applications. The main usage of the Relay was seen in the history of transmitting and receiving the information, that was called as Morse code where the input signals used to be either 1 or 0, these change in signals were mechanically noted in terms of ON and OFF of a light bulb or a beep sound, it means those pulses of 1s and 0s are converted as mechanical ON and OFF using electromagnets.
