2987956

Power Relays, Over 2 Amps

A 2987956 power relay is a switch, usually used in heavy duty applications. It operates from a power source, such as an AC or DC voltage, and is connected to another device, usually a motor or actuators, so that it can be activated when needed. This type of relay is designed to control high currents, usually of more than 2 amps, as a safety device, or as a fail-safe device when used in safety critical applications.

Application Fields:

2987956 power relays are commonly used in industrial, commercial, and safety critical applications. Some of the most common areas where power relays are used include:

• Automotive applications, such as controlling vehicle ignition, headlights, fog lights, and seatbelt warnings.
• Control of portable tools, such as welding machines, belt Sanders, jigsaws, and hedge trimmers.
• Heating and cooling systems, such as air conditioning units, and water heaters.
• Safety systems, such as fire alarm systems, emergency lighting, and smoke detectors.
• Security systems, including access control systems, motion sensors, and CCTV.
• Industrial equipment, such as conveyor belts, robots, and industrial washers.
• HVAC systems, including air handlers, ventilation systems, and chillers.

Working Principle:

When using a 2987956 power relay, the power source (or control device) is connected to one side of the relay\'s switch, known as the input. When a current is applied to the input of the relay, the switch is closed, allowing the current to flow to the other side of the relay, known as the output. The output is then connected to the device which the relay is controlling, such as a motor or actuator. When the current is removed, the switch opens, stopping the current from flowing to the output.

In order to ensure a reliable and safe operation, the 2987956 power relays are designed to withstand voltage spikes, high temperature, and high current. The relays are also resistant to short circuits and moisture, making them suitable for use in a wide variety of environments.

Due to the fact that 2987956 power relays are designed to control high currents, they are usually used in safety critical applications, such as alarms, emergency lighting, and access control systems. This means that the relays must meet certain safety standards to ensure that they are able to protect people and property in the event of an emergency.
