In addition to the remote control of this relay has the advantage, it also has a wide input voltage range(DC7V-DC30V), and input over-voltage protection, input with TVS, as long as the input voltage exceeds 33v, it will automatically protect. Similarly, the input current exceeds a certain value will turn on automatic protection. The circuit board has an output status indicator and an input status indicator. It can be accessed through the TCP client server control can also be controlled through the HTTP protocol, the control of diverse and easy to operate.
Frequently Asked Questions about Relay ESP8266 10A 220V Network WIFI Module Input DC 7V-30V
Q1: What varieties of relays are offered on the market?
Electromechanical Relays
Electromechanical relays have a mechanically moveable contact and an electromagnetic coil. The movable contact, or armature, is drawn to the magnetic field produced when the coil receives the current. A spring retracts the contact when the coil loses power, which also causes it to lose its magnetic field. Large currents can be handled by mechanical relays, but they cannot switch as quickly as other relay types. Depending on the application and design, they can be utilized with either AC or DC currents.
Solid-State Relays
Because they don't have any moving parts, solid-state relays are solid-state electrical components that are more reliable over the long run. The power gain is higher than that of most other relays because the control energy needed is significantly less than the output power. They are utilized for applications like computer transistors because they are often the smallest relays and switch more quickly than other relays. High-speed transistor switches are necessary for the millions of instructions per second that computers execute.
Reed Relays
Reed relays have an electromagnetic coil and a reed switch. Two metal blades, sometimes known as reeds, which are enclosed in a glass tube and filled with inert gas make up the switch. The blades are drawn together and create a closed channel when the coil is supplied with current. No moving armature exists, hence contact wear-out is not an issue. They can switch more quickly than larger relays, and their operation just needs low power from the control circuit.
Coaxial Relays
In situations when radio transmitters and receivers share an antenna, coaxial relays are employed. They change the receiver's radio frequency signal to the transmitters. The receiver is protected by this operation from the transmitter's strong signal. The contacts segregate the receiver and transmitter terminals by not reflecting radio frequency waves back toward the source. They are frequently utilized in transceivers that incorporate a transmitter and a receiver in one device.
Time Delay Relays
With time delay relays, the operation of their contacts is purposefully delayed. A copper disc located between the framework and the moving blade assembly is the reason for the extremely brief delay. The magnetic field is only temporarily preserved by the current via the copper disc, extending the release time. Time delay relays use a dashpot, a piston with fluid or air that progressively escapes, to create a longer delay. The length of the delay varies depending on the flow rate. For longer delays, a mechanical clockwork timer might be attached.
Overload Protection Relays
Electric motors are protected against overcurrent by overload protection relays. A heat-operated relay is a technique used by the overload sensing devices. To operate auxiliary contacts, a coil must generate enough heat to melt a solder pot or heat a bimetallic strip. When the motor overheats, the auxiliary contacts, which are in series with the contactor coil of the motor, shut it off.
