Signal relays are widely used in various types of applications where electrical signals need to be controlled and monitored. In order to better understand the working principle and application field of 2987286 signal relays, we will examine them in greater detail.

In terms of specifications,2987286 relays are suitable for coupling small load currents up to 2 amperes of alternating current. It has a typical power dissipation of 75 mW and a switching time of 17 ms. It is a 1-pole DPDT contact arrangement, with quick-connections for easy installation. These signal relays feature a low voltage range with an AC coil voltage rating of 110 V, and a DC coil voltage rating of 12V.

In terms of application fields, the 2987286 signal relays are ideally suited for applications where electrical signals need to be digitally switched or monitored. Examples may include alarm systems, telephone communication systems, industrial automation processes, automotive systems, and home automation.

The working principle of a signal relay involves the use of electromagnetism to transfer signals. When a current is applied to the coil of a signal relay, it creates a magnetic field which attracts the armature, resulting in the closing of the contact. When the current is removed, the magnetic field decays and the armature is released, thus opening the contact. In this way, a variety of signals can be controlled and monitored electrically.

In terms of safety, the 2987286 signal relays feature a dielectric strength rating of 1000 Volts between coil and contact, a resistance to shock and vibration, as well as a dustproof sealed housing. This ensures long service life and reliable performance in harsh environments.

All in all, the 2987286 relays can handle up to 2 amperes of alternating current and have a quick-connect design which makes them very easy to install. In terms of application fields, these signal relays are suitable for a wide range of electrical control and monitoring purposes, while their robust design offers a dielectric strength rating of 1000 volts and resistance to shock and vibration. Thus, they are the ideal choice for various industrial, commercial, and residential applications.
