Working Principle

The G5LB-1-DC48 power relay operates on the principle of electromagnetic induction. The relay has two main components: an electromagnet and a switch. The electromagnet is the main activating component. It is energized by the applied electrical current, thus creating a magnetic field and generating a force that acts on the switch. The switch is a normally open terminal, which is actuated when the field from the electromagnet is sufficient. When the current is removed from the electromagnet, the switch is released and returns to its original position.

The G5LB-1-DC48 power relay is an effective and reliable solution for DC power control. With its features and working principle, it is suitable for a variety of applications, from automotive and industrial use to PLC control. It is a reliable and cost-effective way to control the power supply of various devices.
