Signal Relays, Up to 2 Amps: EE2-5TNU Application Field and Working Principle

Signal relays are important devices used in a wide range of applications, including automatic control, robotics, semiconductor manufacturing, and industrial automation. The EE2-5TNU is a signal relay from Grundfos, with a capacity of up to 2 amps. It is designed to be small, reliable, and cost-effective, making it ideal for use in a variety of applications.

Signal relays are actuators that convert electrical signals into mechanical movements, enabling them to switch electrical circuits and control signal flow. They are essential for the functioning of other devices such as switches, motors, and solenoids. Relays are commonly used to control power circuits, and to store and transfer data. They are also indispensable in safety systems, often providing the means for remote control and monitoring.

EE2-5TNU Features

The EE2-5TNU is a 5-pin, single-coil relay that is designed for communication applications. It features a range of advanced features, such as a low power consumption (<3W), high switching speed (20ms to 50ms), and long electrical life (100 million cycles). It is also equipped with a standard 1 pole normally open (NO) contact, making it suitable for most low-current applications. The EE2-5TNU is also compatible with most communication standards, including the CDXX-232, TTL, and CAN protocols. This makes it ideal for use in a wide variety of industrial, automotive, and consumer electronics applications.

The EE2-5TNU is small and lightweight, which makes it an ideal choice for applications with limited space. It is also resistant to corrosion, dust, and moisture, making it suitable for use in most harsh environments. Additionally, it has a tight sealing design, which provides superior protection against mechanical impacts, dust, water, and other damaging elements.

EE2-5TNU Working Principle

The EE2-5TNU signal relay works on the principle of electromagnetism. When power is applied to the relay coil, it produces a circular magnetic field, which attracts the armature and closes the contact brush. This reduces the distributional resistance and allows current to flow, thus completing the circuit. When the power is removed, the armature is released and the contacts are disconnected. This opens the circuit, thus interrupting the current flow.

The EE2-5TNU signal relay can be opened and closed by either electrical or mechanical signals. Electrical signals involve either positive (+) or negative (-) voltages and currents. When a voltage is applied to the EE2-5TNU, current will flow through the coil, and the relay will be energized. Mechanical signals involve physical force, such as pushing or pulling a lever. This causes the armature to move and the contacts to be opened or closed.

Conclusion

The EE2-5TNU signal relay from Grundfos is a small, reliable, and cost-effective device, capable of switching low-current circuits up to 2 amps. Its advanced features, such as low power consumption and long electrical life, make it ideal for use in industrial, automotive, and consumer electronic applications. Its working principle is based on electromagnetism, and it can be opened and closed with both electrical and mechanical signals.
