Power relays are electrical switching devices that use a low-power control signals to switch larger power levels. They come in a variety of configurations, types and sizes, and can have various functions. The 2-1617788-7 is an example of a power relay in the over 2 amps category. This section will discuss the application fields and working principle of this relay.

Application Fields of the 2-1617788-7

The 2-1617788-7 is suitable for a variety of different applications, including industrial circuit automation, lighting control, power distribution, vending machines, and any other applications where switches need to be automatically operated by a low current signal. It is specificially designed to convert a low-level logic signal, such as a 5 V or 3 V signal, into a much higher-level power signal for switching large electrical loads such as motors and pumps. This relay is also suitable for other specialized applications, such as energy-saving lighting systems, time-delay switches, and latching switches that need to be operated at a certain time and be turned off automatically.

Working Principle of the 2-1617788-7

The 2-1617788-7 is designed with an integrated two-winding coil in order to convert low-level logic signals into large relay switching capacities. The relay contains a pair of windings that are magnetically coupled to each other. When the relay is energized, a magnetic field is generated that causes the movable contacts of the relay to close. The contact closing, in turn, allows a controlled electric current to flow in the circuit. The relay can be de-energized when the input signal is removed, and the movable contacts will return to their original position.

The working voltage of the 2-1617788-7 is a nominal 6 V DC, but it is also available in 12 V DC and 24 V DC versions. The relay has an approximate resistance of 20 mΩ, an insulation voltage of 500 V, and a contact resistance of 100 mΩ. The relay also has a surge voltage of 1.2 kV.

The 2-1617788-7 is equipped with an integrated latching system, which allows it to remain in the “on” state after the input signal is removed. This feature allows the relay to operate even in the event of a power failure, making it suitable for emergency applications. The relay also has various other features, such as built-in overvoltage and overcurrent protection, and various mounting options.

Conclusion

The 2-1617788-7 is an example of a power relay in the over 2 amps category. It is suitable for a variety of different applications, including industrial circuit automation, lighting control, and power distribution. The relay is designed with an integrated two-winding coil, which allows it to convert low-level logic signals into larger power signals. The relay also features various features, such as an integrated latching system and safety protection features, making it suitable for both standard and emergency applications.
