Power relays are electronic circuits that provide a secure means of controlling the flow of power between two or more components in an electrical system. For applications over 2 amps, the G2R-2A4-H-DC5 Power Relay offers reliable switching with a stable control circuit and high overload capacity. Its specific working principle and application field is detailed further in this article.

Overview of G2R-2A4-H-DC5 Power Relay

The G2R-2A4-H-DC5 Power Relay is a single-pole double-throw (SPDT) relay which uses a sealed contact arrangement with AgCdO (Silver Cadmium Oxide) contacts and a double contact sealing design. Rated at 4A, 120VAC, this type of relay holds a nominal voltage drop of 1.2V during energization when used in applications over 2 amps. It features a built-in surge suppressor that can protect both the load and switch from electric shock or short-circuiting, as well as mechanical latching via a pushbutton for on/off operations. This type of relay can also be provided with LED indicator status and can be easily signalized. Additionally, it has dielectric strength up to 2000VAC for 1 minute.

Features of G2R-2A4-H-DC5 Power Relay

The features of the G2R-2A4-H-DC5 Power Relay include:

• High overload capacity
• High dielectric strength up to 2000VAC for 1 minute
• Seamless mechanical latching via a pushbutton
• LED indicator status
• Built-in surge suppressor to protect load and switch

Working Principle Of G2R-2A4-H-DC5 Power Relay

The G2R-2A4-H-DC5 Power Relay operates on a set of internal contacts and coils. When the input port of the relay receives a DC voltage, it energizes and activates the connected coils, which in turn switch the internal contacts from in "open" position to "closed". This action triggers the power relay to send the control signals or commands to the outputs. Different commands can be set based on the requirement of the system. An example of this could be to switch the AC power load from one side to the other when a certain current is sensed by the relay. Once the signals are received by the output ports, they act as a trigger for the load and the power relay can be disengaged when the input or output is no longer needed.

Advanced Functions of G2R-2A4-H-DC5 Power Relay

The G2R-2A4-H-DC5 Power Relay provides advanced features that provide many benefits. These include the ability to be programmed with a variety of custom functions, such as a timer, counters, and advanced control logic. Additionally, these Power Relays can be used in applications where small size and low power consumption are required, as well as providing remote control functions.

Applications of G2R-2A4-H-DC5 Power Relay

The G2R-2A4-H-DC5 Power Relay offers numerous advantages over traditional electromechanical relays, making it suitable for many different applications. It is most commonly used for applications involving motor control, HVAC, electrical heating systems, lighting control, fault protection, AC/DC motor control, and more.
