Working Principle

The DP4RSA60E20B8 digital plug-in relay is a type of electromechanical operation switch, which mainly works by the magnetic control principle. The coil of the relay is energized when power is supplied, and the rated voltage of the coil is AC 85-265V or DC 20-280V. Once the coil is energized, it will generate a certain amount of magnetic force to drive the switching operation of the contact. Thus, the switching operation is completed. There is also a signal input module inside the relay which consists of an opto-coupler, an LED, and a resistor. The movement of the contact is detected and detected by the signal input module. Then, the system can be notified to act according to the information of the contact.

Overall, the DP4RSA6E20B8 digital plug-in relay is a reliable and cost-effective switching device typically used in automation systems for intelligent switching operations. It has a long-term operation life and a wide range of applications for harsh industrial environments.
