Power Relays, Over 2 Amps

Power relays are widely used for many applications—from controlling small circuits with low currents to managing large circuits with high currents. In particular, G5LB-1-DC12 power relays are designed to control circuits with current ratings between 2 and 12 amps. This article provides an overview of the G5LB-1-DC12 including its application field and the working principle behind it.

Application Field

G5LB-1-DC12 power relays are suitable for use in any number of applications, including telecommunications, automotive, aerospace, medical, and consumer electronics just to name a few. This particular model can be found in many industrial, commercial, and military applications due to its rugged design, reliability, and ability to switch high currents up to 12 amps.G5LB-1-DC12s can be used in both AC and DC circuits. They are capable of switching both AC and DC voltages up to 240VAC and 480VDC, respectively. The contacts are designed to handle resistive loads up to 16A and resistive/inductive loads up to 10A. Also, relays can have either standard or latching operation depending on the application requirements.

Working Principle

The G5LB-1-DC12 consists of two main components: the electromechanical relay and the energizing coil. The electrical current applied to the energizing coil produces an electromagnetic field that closes or opens the mechanical contacts in the relay. When the electromechanical relay is de-energized, the contacts are open, and current cannot flows through the circuit. When the energizing coil is energized, the electromagnetic field created closes the contacts, allowing current to flow through the circuit.

Conclusion

G5LB-1-DC12 power relays are designed to control circuits with current ratings between 2 and 12 amps and to handle AC/DC voltages of up to 240VAC and 480VDC, respectively. The relays are suitable for a variety of applications, including telecommunications, automotive, aerospace, medical, and consumer electronics. They work by having an energizing coil create an electromagnetic field to close or open mechanical contacts in the relay.
