G5LE-1A-CF DC12

Power Relays, Over 2 Amps

A G5LE-1A-CF DC12 power relay is an electromechanical switch used to switch large currents or voltages using just a smaller supply. The main components of such a relay are an actuator, a coil, a contact, and an armature. The actuator is either an electromagnet or a permanent magnet. The coil is either a set of metal strips or a typical turn coil. The contact is a strip of metal that closes and opens the switch. The armature is a movable piece of metal which moves with the current or voltage and activates the contact.

Application Field

The G5LE-1A-CF DC12 power relays are suitable for various industrial and consumer applications such as HVAC, home automation, automotive, motor control, vending machines, release control system, security systems and lighting.
These power relays are also used to switch resistive loads such as incandescent, fluorescent, electric oven, electric motors, and generators. They can also be used to switch inductive loads such as AC motors, transformers, and solenoids.

Working Principle

The power relay works by using a small current which is sent to the actuator (either an electromagnet or a permanent magnet). When the current flow through the coils, a strong magnetic field is created which attracts the armature and moves it. This, in turn, closes or opens the switch, thus switching the load off or on.

The G5LE-1A-CF DC12 power relay is a double pole double throw (DPDT) relay which means that it can switch both the positive and negative terminals of the load. The relay is designed to handle a load up to 12 Amp AC or DC. It also has a voltage rating of 250VAC, 115VDC and a surge current of 25 Amp.

The power relay is designed with two operational modes: latching and non-latching. In the latching mode, the relay is bistable which means that the position of the contacts will remain in either the "on" or "off" state unless pushed in the opposite direction. The non-latching mode requires the relay to be switched manually.

Conclusion

The G5LE-1A-CF DC12 power relay is a reliable and cost effective electromechanical switch used in a variety of industrial and consumer applications. It has a high current and voltage rating and is capable of switching both AC and DC loads. The power relay also has two operational modes- latching and non-latching - making it suitable for various control applications.
