Signal relays are general purpose and PCB style, momentary or latching (bi-stable) available in AC, DC, and high voltage configurations. This particular signal relay, part number 7-1393810-7, is a device designed for handling up to 2 amps rated at 10A AC 250V. It is mainly used as a switch medium to switch low current levels and/or connect them from one circuit to another.

Signal relays serve primarily as a path between two or more electrical points. A signal relay initiates a path to facilitate the flow of electrons and prevent overload. Therefore, the key component of a signal relay is the switching element, which opens and closes the electrical path when necessary. A signal relay uses either a mechanical switch, such as a coil, or solid-state circuitry, such as a transistor, to control the flow of electricity.The 7-1393810-7 features an electromagnetic switch, which is actuated by an electromagnetic field created by the application of an electric current.

When a signal is applied to the input, a magnetic field is generated around the coil, and a current is induced in the switch contact. This current induces a further magnetic field, which acts on the armature of the switch and causes it to rotate. The switch contacts are either open or closed depending on the particular application of the relay. Some models feature a set or adjustable contact distance or contact force.

Signal relays are used in many industrial and consumer applications, such as those used in industrial processes and factory automation, closed loop control, programmable logic controller (PLC) interface, switched engine control, switched lighting control, burglar alarms, door locks, and home automation. The 7-1393810-7 is also capable of being programmed with a pulse-width modulator to ensure smooth operation across different switching times.

Due to its switching capabilities, low cost, and wide range of available voltage ratings, the 7-1393810-7 is a popular choice for many industrial and consumer applications. To ensure reliability and optimum performance, a 7-1393810-7 signal relay should be installed correctly and maintained regularly. The relay can also be used as a protection device to stop the flow of electricity when the input voltage surpasses a certain level, thereby protecting valuable components and circuitry.
