PRD-7AY3-120

Power Relays, Over 2 Amps

The PRD-7AY3-120 is a power relay which is used to automatically control one or more loads when a specific condition is reached. It is an electromechanical relay with a contact capacity of 2-4 Amps in resistive circuit and 1-2 Amps in inductive circuit and has both normally open and normally closed contacts. It is capable of interrupting large current and featuring small size, high reliability, low cost, and optimized selection.

Application Field

The PRD-7AY3-120 is widely used in the industry, such as refrigerators, air conditioners, range hoods, computers, communication equipment, UPS power, elevators, and automatic door controllers. It can control the single power source or multiple power source. It can also be used in the consumer industry, like household appliances, security systems, burglarproof and fire fighting equipment. Its contact part material can meet different needs, such as 24VAC/DC, 30VAC/DC, 120VAC/DC, 240VAC DC, etc.

Working Principle

The PRD-7AY3-120 is an electromechanical relay and thus it works based on a set of specific rules. When the contacts are energized, a magnetic coil is activated, which moves a plunger inside a solenoid. The plunger closes the contacts of the relay, allowing current to flow from an input source to the output device. When the contacts are energized, the plunger moves the plunger back, reshaping the contacts to their original position and thus opening the couple, thus interrupting the current.

The PRD-7AY3-120 is a low-noise, economical and dependable power relay solution for controlling single or multiple loads. With its high reliability, low cost, and optimized selection, it is the perfect choice for industrial and consumer applications.
