Working Principle of ALE72B18

The ALE72B18 is an electromagnetic relay that uses a coil to generate a magnetic field, which controls a set of contacts. The contacts open and close depending on whether the coil is energized or not.When the relay is energized, a magnetic field is generated, which turns on the contact set.

The ALE72B18 uses direct current (DC), which allows for greater contact control resolution and a faster switching time. The coil resistance is rated at 50ohm, and the maximum switching voltage is rated at 24VDC and switching current rated at 2Amp. The relay also features LED indication, allowing for visual monitoring of relay status.

The ALE72B18 features an array of safety micro switches to protect from inadvertent contact closure, and an integrated diode to protect its coil from voltage spikes. Its small form factor and low profile design makes it compatible with high density circuitry.

Conclusion

The ALE72B18 is a versatile power relay designed for use in a variety of applications. It is capable of switching up to 2 amps and features an array of safety micro switches and voltage spike protection. Its small form factor and low profile design makes it ideal for use in high density circuitry. Its usefulness in controlling machinery, climate control systems, power supplies and other electronic components makes it a reliable and cost-effective solution for industrial and commercial applications.
