Signal Relays, Up to 2 Amps

Signal relays are widely used to control large amounts of current with a small signal. Common applications include switching circuit breakers, starting and stopping electric motors, and providing overload protection. They can be used in many different circuits, with a wide range of current capacities. This article looks at one particular type of signal relay, the 2826172, and examines its application field and working principle.

Introduction to 2826172 Signal Relays

The 2826172 signal relay is a normally open, electrically controlled switch that is rated for up to 2 amps of current. It has an input voltage range of 4 to 14 Volts, and a coil resistance of 315 ohms. The maximum operating temperature of the relay is 75°C. It has two independent sets of contacts, an SPST-NO (single pole, single throw, normally open) contact, and an SPDT (single pole, double throw) contact.

Application Field of 2826172 Relays

The 2826172 relay is well suited for applications that require precise control of larger electrical loads. It is often used to control motor loads, such as starting and stopping an electric motor. It can also be used to control circuit breakers, providing protection against overloads or short-circuits. It is also used in switching applications, such as switching between two different circuits.

Working Principle of 2826172 Relays

The 2826172 relay operates on the principle of electromagnetic induction. When an electric current is passed through the coil of the relay, it induces a magnetic field which operates the switch. Depending on the polarity of the current, the switch will either open or close, allowing current to flow through the contacts.

Safety Considerations When Using Relays

When using a relay, it is important to consider safety and proper installation. The relay must be installed in a manner that does not pose any risk of electrical shock to personnel or equipment. The connections must also be correctly identified and connected in the proper order. All wiring must be of the proper gauge and installed using approved methods.

Conclusion

The 2826172 relay is a versatile and reliable signal relay that can be used for a wide range of applications. Its rated current of up to 2 amps makes it suitable for controlling larger loads, and its wide input voltage range makes it a suitable choice for many different circuits. When properly installed and used, it is an effective tool for controlling electrical devices.
