Signal Relays are designed to control low-level signals, such as those from sensors and actuators, allowing them to be connected to a larger system. Up to 2 Amps Signal Relays are designed to switch on or off a variety of signals, including both AC and DC, while maintaining the signal’s original form. 7-1393812-9 is a signal relay which offers this capability with various features, such as a rated current of up to 2 Amps and a contact form of SPDT. In this article, we will discuss the application field and working principle of 7-1393812-9.

Application Field

The most common applications of 7-1393812-9 are to control signals with small amperage, such as those from actuators and sensors, allowing them to be connected to a larger system. These relays are also used in the field of automotive electronics, where they can be used to control low-level signals from various sensors and monitor the state of vehicle components. Other applications include medical equipment, industrial automation, consumer electronics, and robotics.

Working Principle

The 7-1393812-9 offers SPDT (single-pole double-throw) contacts for the switching of signals. The contacts are kept open when no signal voltage is applied to the relay. A signal voltage is then applied to actuate the contacts, allowing the switching of signals. The contacts are normally closed when a signal is applied, and open when it is removed. It is important to ensure that the current load does not exceed the rated current of 2 Amps, otherwise the contacts may become damaged.

The 7-1393812-9 also features a built-in LED indicator light, which can be used to indicate the state of the relay. The LED is lit when the contacts are closed, and will turn off when the contacts are open. This feature is especially useful for debugging and troubleshooting purposes, as it allows the user to quickly identify the state of the relay.

In summary, 7-1393812-9 is a signal relay which is designed to switch on or off signals with a rated current of up to 2 Amps. It offers SPDT contacts for the switching of signals, as well as a built-in LED indicator light for troubleshooting applications. Its wide range of applications and features make it a versatile tool for use in many fields.
