38 current sensing relay circuit diagram
5,707 views. Today we are going to demonstrate a project of a Temperature sensor relay switch circuit. This is just like a normal heat or temperature sensor with a relay so whenever the circuit will receive heat the relay will activate and so will the load or device connected to the relay. Any AC 110V or 220V or DC appliance can be connected to ... Figure 7 shows the current limit starter circuit diagram. Current sensors are placed in series with each of the starting resistors. When the armature current drops to a low enough value, the current sensor S1 causes relay S1 in the control circuit to close, thus energizing coil 1A and shorting out resistor Rl. Basic schematic circuit diagram of Relay. The following schematic shows the basic circuit. Connect the relay with HC11 port pins this is used to control on switches. The transistor allows the HC11 to control the medium sized coil current of relay. The diode prevents relay from arcing by giving a return path for the energy sto...
