Signal Relays, Up to 2 Amps

UD2-12NUN-L is a kind of signal relay which is designed for signal switching up to 2 amps. It uses a coil to actuate one or more power contacts when energizing. Its switching contacts are capable of carrying both AC and DC current, and it is designed for applications ranging from industrial automation to telecommunication applications.

The UD2-12NUN-L signal relay can be used to control high current loads such as motors, lights, and solenoid valves. It can also be used to protect the circuit from over-voltage and over-current, and to switch rapidly between on and off-state. It has a small coil that requires minimum power to drive the relay and can switch between high and low voltage levels in a very fast manner. By using the UD2-12NUN-L, it is possible to switch high-current signals with low power consumption (less than 3W) and quickly.

The UD2-12NUN-L signal relay consists of an integrated internal coil, a diode, and a pair of contacts that are connected to each other and provide isolation from the external environment. When the relay is energized, the internal coil generates a magnetic field to pull the moving contact against the stationary contact. When the relay is de-energized, the magnetic field dissipates, and the contacts are no longer connected. This is known as the make-break principle.

UD2-12NUN-L relays are suitable for a wide range of applications, from high current switching and protection to control small current and voltage signals in the telecommunications and industrial automation sectors. It has a high noise immunity, making it very suitable for applications in adverse environment and with high levels of electrical noise. The switching is highly reliable and works in both AC and DC signals.

In addition, the UD2-12NUN-L Relay provides a high degree of protection to the external environment, as it has a built-in diode to protect from over-current and over-voltage, and it also has a robust magnetic shield to avoid EMI/RFI noise from affecting its operations. It is also resistant to vibrations and offers several mounting options for ease of installation.

UD2-12NUN-L relays are easy to integrate into existing control systems and provide reliable switching performance for both AC and DC applications. The long-term reliability of this signal relay makes it a great choice for applications that require frequent switching operations.
