Signal Relays, Up to 2 Amps

Signal relays are electronic control devices intended to control low voltage electrical circuits. The 1393812-9 is a signal relay designed to switch currents up to 2 Amps. It is small, able to be mounted on a circuit board, and has an operating temperature range of -20 to +80 C. The unit is powered by either AC or DC voltage and is very versatile in its application.

Application Field

The 1393812-9 signal relay is suitable for a wide range of applications, including automotive, industrial control, consumer electronics, medical equipment, and home appliances. It can be used for lighting control, motor control, power conversion, machine tools and process control applications. The relay has a safety feature which prevents it from operating if the power fails or is disconnected.

Working Principle

The 1393812-9 signal relay operates on the principle of electromagnetic induction. When an electric current is passed through a coil, it creates a magnetic field which can be used to open or close a switch. In this relay, the switch is opened or closed by energizing the coil which is provided with DC or AC power. Once the coil is energized, it creates a magnetic field which attracts a plunger arm which is connected to the switch contacts. This moves the switch either in the open or closed position depending upon the type of input voltage used.

The output contacts of the relay connect the power source to the external device, such as a motor or a light switching circuit. When the coil is energized, the contacts are switched on and the external device is powered. When the coil is de-energized, the contacts are again switched off and the external device is disabled.

The internal components of the relay are designed for maximum reliability with minimum power consumption. It has a robust construction and a long operational life. The relay is designed to be operated in an environment with a wide range of temperatures and humidity levels.

The 1393812-9 signal relay is a reliable, efficient and cost-effective choice for a wide range of applications.
