Signal relays provide an efficient way to control electric currents and signals without the need to use manual switches or automation. They work by activating a magnetic field within a metal coil which opens or closes a contact port. One of the most popular types of signal relays used are HC4E-H-AC115V, which provides up to 2 amps of current. This article will discuss the application fields and working principle of these signal relays.

Application Fields

HC4E-H-AC115V signal relays can be used in a wide variety of applications. They are commonly used in industrial and medical settings as a way to control electrical signals and currents without the need to manually activate a switch. They are also used in remote controlled devices such as drones and robots, where a remote signal can be sent to activate a circuit. Additionally, these signal relays are used in industrial automation, providing an efficient way to automate a process without the need for human intervention.

Working Principle

HC4E-H-AC115V signal relays work by using an internal coil of wire and an electromagnet. When electricity is applied to the coil, it creates a magnetic field that moves a switch or contact port. This allows the signal relay to work as a remote switch, allowing for control of an electric signal without the need for manual intervention. The magnetic field also allows the signal relay to provide up to 2 amps of current, which is suitable for many different types of applications.

The HC4E-H-AC115V signal relays can also be used to provide both single-pole double-throw (SPDT) and double-pole double-throw (DPDT) outputs. SPDT outputs typically provide a single controlled output that can be switched on or off, while DPDT outputs provide two separate outputs that can be controlled independently. These outputs are ideal for controlling multiple electric signals in a single operation.

HC4E-H-AC115Vs can also be used for pulse-width modulation (PWM) applications. In a PWM application, a signal is sent to the signal relay at specific intervals, activating the relay and providing a specific level of current to the output of the system. This allows for precise control of electric signals without the need for manual control.

Overall, the HC4E-H-AC115V signal relay provides a reliable and efficient method of controlling electric signals and currents. They can be easily integrated into a wide range of applications, and provide up to 2 amps of current. This makes them ideal for industrial, medical, and remote-controlled applications, as well as applications that require pulse-width modulation.
