G2R-1-H-DC24

Power relays, with their ability to control electrical systems, can replace manual labor and reduce costs in industrial and commercial applications. With relay ratings of over 2 Amps, they are often used in high-amperage power circuits. One such relay is the G2R-1-H-DC24, which is designed for single-pole double-throw (SPDT) switching applications. This article will analyze the G2R-1-H-DC24’s application fields and working principle.

Application Fields

The G2R-1-H-DC24 relay is designed to control high-amperage power circuits, including 3-phase motor control circuits. It is rated at 24A, meaning it can handle loads of up to 24A. Other applications include AC power control, light-load switching, and DC control.

The G2R-1-H-DC24 is suitable for both DC and AC switching. It has a maximum voltage rating of 250VAC and is UL, CSA, TUV, and VDE approved. This makes it suitable for use in hazardous-location applications. It is also RoHS compliant, making it suitable for use in environmental applications.

Working Principle

The G2R-1-H-DC24 relay is used to switch high-amperage AC or DC power circuits on or off. The relay is connected to a power source, such as a battery, wall outlet, or motor. When power is supplied to the relay, a solenoid coil inside the relay is energized, causing an armature inside the relay to move. The armature trips the switch contacts, either breaking or making the circuit.

The relay can be activated and deactivated using various control signals, such as a mechanical switch, optical sensor, or timer circuit. These signals provide a low-voltage or current to the relay, causing the coil to be energized and the armature to move. When the control signal is removed, the armature returns to its original position, either opening or closing the contacts.

The G2R-1-H-DC24 has a wide range of features that make it ideal for difficult applications. It is equipped with a dust cover and seals to protect against dust, moisture, and other contaminants. It also has a high vibration resistance for applications in harsh environments. Additionally, the relay has a surge-resistant design that helps to protect it from voltage spikes.
