Power Relays, Over 2 Amps

The 8897240000 is a power relay capable of handling current in excess of 2 amps. It is a double-pole, double-throw (DPDT) device, allowing for two sets of independent circuits to be actuated simultaneously. This type of relay is primarily utilized in industrial applications where large currents must be controlled, such as in automation, machine tools, and robotics.

The 8897240000 is operated mechanically, through an electromechanical relay designed to be actuated by an electrical signal. When energized, the coil of the relay creates a magnetic field which causes a contact armature to move, thus completing one of two designated circuits. The two circuits, known as a \'Common\' and \'Normally-Open\' or \'Usually-Closed\', are connected electrically when the relay coil is energized. This provides switching of two sets of contacts, which can consequently turn equipment on or off.

The 8897240000 is typically composed of a relay coil, two sets of contacts (common and one of the two circuits mentioned above), two set screws (for electrical connection), an armature (attached to the coil for actuation), a housing, and two insulating plates. The plates electrically isolate the two sets of contacts and are made of either plastic or non-conducive metal. The housing is typically composed of die-cast zinc, steel, aluminum or aluminum alloy for maximum durability.

In terms of power rating, the 8897240000 can handle up to 10 amperes at 250 volts AC, or 6 amperes in DC or 400 watts of power. It can operate over a temperature range of -55°C to +120°C and is UL approved.

In operation, the 8897240000 is actuated by an electrical signal applied to its coil. This causes the armature to move, which completes either the \'Common\' circuit or the \'Normally-Open/Closed\' circuit, depending on the type of relay. The type of actuator is determined by the specifications of the circuit being used and the load that needs to be switched. Additionally, for safety purposes, the contact armature is biased to the off position and power is applied to the coil to close the circuit.

The 8897240000 is an effective and reliable power relay. Its ability to switch two sets of circuits independently makes it ideal for use in automation and machine tools. Additionally, its durability and safety features make it a desirable device for industrial applications.
