The working principle and characteristics of 10A relay

When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the electrical appliance that makes the controlled output circuit turn on or off. It can be divided into two categories: electrical quantity (such as current, voltage, frequency, power, etc.) relays and non-electrical quantity (such as temperature, pressure, speed, etc.) relays. It has the advantages of fast action, stable work, long service life and small size. Widely used in power protection, automation, motion, remote control, measurement and communication devices.

10A relay is an electronic control device, it has a control system (also known as input loop) and a controlled system (also known as output loop), usually used in automatic control circuits, it actually uses a smaller current to control more A kind of "automatic switch" for high current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

Main product technical parameters of relay

1. Rated working voltage

It refers to the voltage required by the coil when the relay is working normally. Depending on the model of the relay, it can be either AC voltage or DC voltage.

2. DC resistance

Refers to the DC resistance of the coil in the relay, which can be measured by a meter.

3. Release current

Refers to the relay to generate a larger current for the release action. When the current in the pull-in state of the relay is reduced to a certain extent, the relay will return to the unenergized release state. The current at this time is much smaller than the pull-in current.
