F51S20A is a kind of special electrical relay, which has powerful functions and can be applied to various fields. According to the comprehensive technical parameter, this kind of special electrical relay is suitable for industrial, instrumentation, machine tool and tester control system, integrated circuit protection and anti-interference protection, and can also be used in automatic control and power distribution.

The working principle of F51S20A is a bit more complex. It has two main functions, which are voltage protection and signal control. When the source voltage exceeds the set upper and lower limit values, it can quickly switch off the electric current to better protect the safety of the controlled equipment. This kind of special electric relay can be configured to some specific functions, they can be used for the control of machine tools, automatic production line, protective devices for various switchboxes and power distribution boxes, and required signal control.

In instrumentation, F51S20A can be used for measuring instruments and automatic control system as it can quickly respond to the current signals and then automatically switch off the electric current, so that it can protect the measuring instruments or automatic control system against damages from high or low currents. Besides, such devices also act as signal control. If voltage or current is over the current limitation, the device will prompt the user to pay attention to the abnormal situation.

In machine tool control system, F51S20A can be used as a power supply protection device, while at the same time it can detect the real-time current state of the machine tool and control the cutting speed, cutting force and other parameters. Moreover, it can also detect the temperature rising to prevent the gear from being burned out or other abnormal situations.

As for tester control system, F51S20A can precisely and quickly detect the current changes and circuit connection states, and rapidly control the current, so that to ensure the accuracy of the test. The integrated circuit protection system also takes advantage of this kind of special electric relay as the protection switch, with which the unexpected high or low current can be prevented, so that the circuit won’t be damaged due to wrong connection.

In addition, F51S20A can also be used in the power distribution system. By rapidly detecting the variation range of circuit voltage or current, F51S20A can maintain the normal working condition of power distribution system and prevent from overvoltage, overcurrent, reverse phase sequence and other accidental issues that can cause power distribution system failure.

In summary, F51S20A special electrical relay is widely used in industry, electric instrumentation, machine tool and tester control system, integrated circuit protection and power distribution system due to its powerful function and exquisite design. Its working principle is to detect the source voltage quickly and set off the electric current in order to protect the safety of the controlled equipments or systems.
