Power relays are solid-state or electromechanical devices that control electrical circuits by responding to input signals that open or close switches. HJ4-L-AC120V-R-6 is a power relay with a rated load current of more than two amps. It is suitable for high power load applications that require relay switching. The device is designed for asynchronous motor control applications in combination with programmable logic controllers (PLCs).

Application Field

The HJ4-L-AC120V-R-6 is suitable for a broad range of industrial applications including:

• Starting and stopping of asynchronous motors
• Control of direct-on-line starters, star/delta starters, reversible starters and reversing starters
• Induction heating control applications
• Solvent extraction systems
• Pumping equipment

The HJ4-L-AC120V-R-6 can be used in low-voltage, three-phase asynchronous motor control systems such as conveyor belts, elevators and cranes. It can also be used in serial communication networks to integrate motor control and monitoring systems. It is ideal for automation and process control applications.

Working Principle

The HJ4-L-AC120V-R-6 is an electromechanical device that is operated based on input signals from a controller. It can be used to switch a circuit on or off, and can also be used to control the speed of an asynchronous motor. It operates based on the principle of electromagnetic induction. When a voltage is applied to the relay, it creates an electric current that causes an electromagnetic field to be created around it. When the output signal is on, the electromagnetic field pulls a plunger or solenoid to complete a circuit, allowing the motor or electrical load to be powered up.

The device can be operated manually or automatically by a programmable logic controller (PLC). In manual mode, the user can press a button to activate or deactivate the motor or electrical load. In automatic mode, the device automatically switches the circuit on or off depending on input signals from the PLC. The user can also configure the device to operate automated motor control systems such as conveyor belts and elevators.

The HJ4-L-AC120V-R-6 is a reliable power relay with a rated load current of more than two amps. It is suitable for high power load applications that require precise switching control, and is ideal for automation and process control applications such as asynchronous motor control systems.
