3-1393809-7

Signal relay 3-1393809-7 is a component typically used for control circuitry. It works by using a coil to close an interrupting contact used to send a signal or current to turn things on and off. This particular relay works up to 2A and can be used for a variety of applications.

The first application of the 3-1393809-7 relay is in a motor control circuit. This circuit consists of a relay coil, an interrupting contact, and a power supply. The purpose of this circuit is to control the speed of a motor by turning it on and off with each rotation of a motor shaft. This can be done by using the interrupting contact on the relay to interrupt the current to the motor at predetermined intervals. This ensures that the motor continues to run at the desired speed.

Another application of the 3-1393809-7 relay is in a lighting control circuit. This circuit consists of a relay coil, a timer, and a power supply. The purpose of the circuit is to control the amount of time that a light stays lit. This can be done by setting the timer to turn off the power to the light when the preset time is reached. This ensures that the light comes on and off in a controlled manner and helps save energy.

One of the most popular applications of the 3-1393809-7 relay is in an access control system. This system consists of a relay coil, interrupting contact, power supply, reader, and control panel. The purpose of the access control system is to grant or deny access to a certain area with a card or key fob. This is done by using the interrupting contact on the relay to interrupt the current from the reader to the control panel. This ensures that only certain people have access to the area and can help with the security of the area.

The working principle of the 3-1393809-7 relay is relatively simple. It is an electromagnetic switch that is triggered when a current is applied to the coil. This causes the interrupting contact on the relay to close and turns the device on. When the current is removed from the coil, the contact opens again and turns the device off. This makes it easy to control the current without the need for any additional devices or circuits.

In conclusion, the 3-1393809-7 relay is a versatile component that can be used for a variety of applications. It is a relatively simple component that works by using a coil to close an interrupting contact to send a signal or current. This allows for easy control of devices and circuits without the need for additional devices or circuits.
