Time Delay Relays are an alternation to regular relays and are specifically designed to provide delayed action when a voltage is applied to the relay\'s coil. One of the most popular types are the SHS20S220A relays. Let\'s take a deeper look at the application field and working principle of these relays.

Application Field

The primary use of the SHS20S220A Time Delay Relay is for industrial control systems that require a delay-on triggering. An example of its application is in industrial automation systems where the adjustment of an output effect needs to be delayed. This means that the SHS20S220A can be used in applications such as process control, machine tool automation, and safety automation, all of which can benefit from a delayed effect.

Another popular use of Time Delay Relays is in motor starters and pumps. These are used to delay the start up of motors and pumps to ensure that they start properly. The SHS20S220A Time Delay Relay will provide the delayed start up of these systems without manual reset. This means that the motor or pump can start up reliably and efficiently without the need for resetting.

Working Principle

The working principle of the SHS20S220A Time Delay Relay is based on the voltage applied to the relay\'s coil. When power is applied to the coil, it will generate a magnetic field which is used to actuate a mechanical spool. When the spool is actuated, it will trip the contact arm and open a contact on the Time Delay Relay. The operation time of the contact is determined by the resistance and capacitance of the integrated circuit capacitors within the Time Delay Relay. This means that the Time Delay Relay can be adjusted to suit the application that it is being used for with precision.

When the application requirements change, the Time Delay Relay can be adjusted accordingly. This makes it very convenient for engineers to adjust the Time Delay Relay without having to replace it. It also ensures that the Time Delay Relay provides accurate and reliable operation.

The SHS20S220A Time Delay Relay is also very reliable and can operate at high temperatures without any problems. This is because the relay is constructed from high temperature materials which makes it durable in harsh industrial environments. The SHS20S220A also has a wide operating voltage range, from 9 to 57V, making it suitable for a variety of applications.

Conclusion

In conclusion, the SHS20S220A Time Delay Relay is an excellent choice for industrial control systems that require a delayed effect. It has a wide range of applications, from motor starters and pumps, to industrial automation systems. It is also very reliable and can operate in extreme temperatures. The Time Delay Relay can also be adjusted to suit the application requirements with precision, making it a very versatile and reliable relay.
