Signal relays are electrically operated switches used to enable control of power to electrical devices. Signal relays can be used to switch high voltage and/or high current circuits and are classified according to their operating voltage, current rating, switching type, response time, and contact arrangement. In this article, we will discuss 1422002-8 efficient signal relays with up to 2amps.

What is 1422002-8?

1422002-8 is a signal relay manufactured by one of the leading signal specialist companies, Omron. It is a single pole, double-throw (SPDT) signal relay specifically designed for medium power control applications. The device is equipped with low-noise contacts that enable it to operate quietly and over long periods of time without causing any disruption. It is rated at up to 2amps and features a built-in relay buffer circuit.

Application Fields:

1422002-8 signal relays are widely used in the telecommunications, medical, and transportation industries. The device is suitable for controlling long distance or heavy-duty switching. It is also used for controlling switches in machines used to move high-weight transportation equipment, such as elevators and cranes. Furthermore, this type of signal relay is also used in industrial automation systems, where it is used as a governing device to activate specific equipment and operations.

Working Principle:

A 1422002-8 signal relay consists of two main parts, the coil and armature. The coil, when energized, creates a magnetic field, activating the armature to engage and form the contact. When the coil is de-energized, the contacts return to their original state. This type of device is normally used in switching operations, or for controlling current in an application.

Contact Arrangement:

The contact arrangement for the 1422002-8 signal relay is a single pole double-throw (SPDT) switch, in which one of two separate circuits is connected, depending on the device’s position. The contact arrangement is such that when the relay is energized, one of the circuits is connected and when the coil is de-energized, the other circuit is connected.

Spectrum of Rated Loads:

The spectral range of rated loads for the 1422002-8 signal relay is between 0.1 and 2 amps. Its contacts are rated at 0.2A at a rated voltage of 200V, and its switching capacity is 0.2VA at 250 VAC. The designed electronics of the relay body has a Low Noise Buffer Circuit, which reduces EMI/RFI disturbances caused by noise and vibration during operation.

Switching Response Time:

The switching response time of the 1422002-8 signal relay is quite fast. The operation time is 0.1ms to 0.7ms with input ON, and 0.1ms to 1.0ms with input OFF. The release time is 0.15ms to 1.5ms with input ON, and 0.15ms to 10.0ms with input OFF.

Benefits:

The 1422002-8 signal relay is a highly efficient device with a number of benefits. It is competitively priced, making it an affordable choice for different types of applications. It ensures a long lasting performance, as it is designed with low noise contacts that reduce the chance of disruption. This device is also easy to install and maintain, as no additional wiring is required. It also requires minimal power, making it an energy-efficient choice.

Conclusion:

In conclusion, the 1422002-8 signal relay is an ideal choice for medium power control applications. It is an efficient device, capable of rated loads up to 2amps, with a switching response time of 0.1 ms to 0.7ms. It is competitively priced, making it an affordable choice for many applications. Finally, its built-in buffer circuit ensures a quiet operation with minimal interference.
