Overview

1-1393140-1 Application Field and Working Principle Power relays are used in a variety of applications and industries. In cases where the load current is greater than 2 amps, a power relay is used.

How Power Relays Work

Power relays operate on an electromechanical principle, where electrical input is converted to mechanical output. The turning on and off of a power relay’s load device is determined by a set of contacts that are regulated by the control circuit. When a current is applied to the control circuit, it in turn applies a force to the contacts, forcing them to switch state, either opening or closing depending on the circuit.

Relay Types

A variety of power relays exist, each suitable for a different application. The two main types are latching and non-latching relays. Non-latching relays are used for continuous switching operations, where the contacts switch state with each cycle, while latching relays are used in applications where the switch state needs to be locked in to ensure that the load device remains on or off.

Operation and Control

Power relays operate in either an analog or digital format. Generally speaking, analog relays are used in high current, continuous switching applications, such as for automotive and industrial applications. Digital relays are used for more complex control circuits and in more intricate applications, such as robotics.

Sizing and Rating

When selecting a power relay for a given application, the size and the rating of the relay must be taken into consideration. Loads that exceed the maximum contact voltage or current capacity of the relay may damage it or cause it to malfunction. It is important to research the application and select the proper relay based on the load requirements.

Contacts and Contact Arrangement

The number of contacts and the contact arrangement are also important factors in selecting the proper relay. A 1-1393140-1 may have multiple contacts, a normally open contact, a normally closed contact, or a combination of both. Depending on the application, the contact arrangement may vary, as well as the number of contacts.

Relay Mounting and Packaging

Power relays are available in both surface and through-hole mounting packages, as well as various types of envelopes. Surface mount relays tend to be used in high-density and space constrained applications, while through-hole relays are typically used in applications where more space is available. Additionally, some relays may come with extra features, such as LED status indicators or pre-attached connectors.

Benefits of Power Relays

Power relays offer a number of advantages over traditional electromechanical components. They are highly reliable, have a long lifetime, are energy efficient, and are relatively low in cost. They are also smaller in size, making them suitable for applications in tight spaces.

Conclusion

The 1-1393140-1 is a power relay rated for greater than 2 amps. It is suitable for applications in industries such as automotive, industrial, and robotics due to its wide range of features and its ability to be used in tight spaces. When selecting a power relay for a given application, the load requirements, contact arrangement, and mounting package must all be taken into consideration.
