Mini DC12V 1A Signal Double Coil Relay 0.2W PCB For Traffic System
12V Relay Working Principle:
Electromagnetic relays are generally composed of an iron core, coil, armature, contact reed, and so on. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The moving contact and the static contact (normally open contact) are sucked together. When the coil is de-energized, the electromagnetic suction will disappear, and the armature will return to its original position under the reaction force of the spring so that the moving contact and the original static contact (normally closed contact) will be released. In this way, it is attracted and released, so as to achieve the purpose of conducting and cutting off in the circuit. For the "normally open and normally closed" contacts of the relay, it can be distinguished in this way: the static contact that is in the off state when the relay coil is not energized is called "normally open contact"; the static contact in the on the state is called "normally closed contact".
12V Signal Relay Features:
1. 200mW of low power consumption
2. High dielectric withstand voltage of 1000VAC between coil and contact
3. F class for coil
4. SPDT form, high sensitivity
5. Mini-size, lightweight
12V Signal Relay Applications:
1. Computer mainboard
2. Traffic light system
3. Leakage protector

12V Signal Relay introduce:
A relay is an electrical control device, which can give a specified input quantity and maintain it for a long enough time to make a predetermined step change in the controlled quantity in the electrical output circuit. When the input volume is reduced to a certain level and maintained for a long enough time, it returns to the initial state.
