ADY12006

Power Relays, Over 2 Amps

The ADY12006 is a power relay with over 2 amps capability. It is a general-purpose three-pole relay designed for high-power industrial applications. This relay has two contacts in Parallel (P) configuration and a normally open contact (NO) available for load control. It is designed to provide three power levels, depending on the application: a low power level for switching DC or AC signals, a mid-power level for switching low voltage electrical devices, and a high power level for controlling higher voltage and load currents in industrial applications.

Application Field

The ADY12006 power relay is suitable for a variety of power control applications, including AC and DC furnace controls, control of pumps and motors,lighting and circuit switching, railroad signaling, and other general-purpose power control. This type of power relay can handle up to three different power levels, for industrial applications such as electric control panels, control enclosures, and uninterruptible power systems, as well as for more specialized tools and equipment.

Working Principle

The ADY12006 power relay works by sensing a voltage differential across the arms of the relay coil. When a voltage across the relay’s coil increases beyond the preset level, the relay’s contacts close to open a circuit or power a device, depending on the type of relay and its programming. When the voltage across the coil decreases below the preset level, the relay contacts open to deactivate the circuit or disconnect the power.

The contacts of the ADY12006 power relay are made of tungsten, a material that is highly resistant to high temperatures associated with power switching. The contacts can also be made of silver, gold, or platinum for even greater heat resistance. The contact surfaces are protected from oxidation by an oxide film, and the relay is also equipped with arc suppression circuitry to reduce arcing and electrical noise.

The ADY12006 power relay can also be used in reverse-polarity applications, for which the power can be reversed to activate or deactivate the circuit. This power relay also offers an optional normally-closed contact, which can be operated manually or automatically to control an external power device.
