Power Relays, Over 2 Amps

9-1617755-3, or "9 Series" takes on relays with memory. This type of relay is perfect for applications where a few contacts need to be switched within a frequency or to be turned on or off. The 9 Series is designed to be used in the power range exceeding 2 amps, allowing for larger pieces of equipment to be controlled efficiently and accurately.

Application Field

The 9-1617755-3 relay series is perfect for applications that require a switch with memory to be switched. This type of relay is primarily used for motor starters, pumps, HVAC units, and other pieces of equipment with electric control systems. It is especially useful for systems which require a high degree of accuracy and reliability in order to function correctly.

This type of relay provides precise switching with judicious levels of current. This is advantageous as it allows for a quick switch to its required contact, reduce the static power loss, as well as improve the number of times the contact can be switched without failure. This improves the operational life of the relay, making it suitable for applications that require long term or repetitive switching.

Working Principle

The 9-1617755-3 relay series utilizes three-circuit cutouts of the switching modules. Two of these circuits, the driving and contact circuits, are used to operate and control the switching action. The third circuit, the power circuit, supplies the necessary voltage to the driving and contact circuits.

The driving circuit uses a coil to create a magnetic field, which is then used to activate the contact circuit. When the coil is energized, the magnetic circuit \'pulls\' the contact from the armature, allowing current to flow. The contact circuit also involves an armature and contact. As the armature moves, it opens and closes the contact present in the circuit.

The power circuit is responsible for supplying the voltage to these circuits. The number of volts is determined by the series of relay itself. The power circuit also includes a resistor, which is used to reduce the current in the drive circuit, allowing it to switch at the desired frequency.

Finally, the relay also includes auxiliary contacts. Auxiliary contacts are contacts which are intended to be used in addition to the normal contact circuit. These contacts are typically used to activate other items, such as alarms or lights, when the standard contact is closed.

Benefits of 9-1617755-3 Relays

The reliability and accuracy of the 9-1617755-3 relay series make it a great choice for many different types of applications. It is used in motor starters, pumps, HVAC units, and other pieces of equipment with electric control systems due to its ability to switch with precision and reliability. Additionally, the number of volts needed for operation is predetermined by the series, allowing it to be used easily in a variety of situations without requiring any additional modifications. Finally, the inclusion of auxiliary contacts allows for further flexibility and control over the application, making the 9 Series a great option for any situation requiring a reliable and precise switch.
