Time Delay Relays

Time delay relays are a type of electrical device used to control the timing processes of machines, components, and processes. The FS127 time delay relay is a popular model of this type of device.

What is a Time Delay Relay?

Time delay relays are a type of relay which uses a timing mechanism to control the on/off switching of an electrical circuit. They are most commonly used to control sequence of events in industrial processes, operate machinery and equipment, and for general time delay applications. Generally, the time delay relay is used to start, stop, reset, or to initiate alarms at predetermined times. The FS127 is a particularly popular time delay relay due to its flexible use and applications.

FS127 Time Delay Relay

The FS127 time delay relay is a 8 pin DIP switchable time delay relay with a voltage rating of 50V-240V AC and a power output of 8A. It works by applying a voltage to the input terminals of the relay (Pin 2 and 8), causing an internal timer to start counting down. After a preset time, the output contacts (Pin 5 and 7) open or close the circuit. The FS127 also offers adjustable timing ranges, making it one of the most flexible time delay relays available.

FS127 Application Fields & Working Principle

The FS127 time delay relay can be used in a variety of applications such as cooling fan control, PLC applications, industrial process control, light control, equipment safety shutdown and security systems. The working principle of the FS127 time delay relay is similar to that of most other time delay relays - when voltage is applied to the input terminals, the internal timer begins counting down. After the preset time has passed, the output contacts of the relay open or close, depending on the time setting chosen. This process is repeated as long as voltage is applied to the input terminals.

Conclusion

The FS127 time delay relay is one of the most versatile and flexible relays on the market and can be used in a variety of applications. Its adjustable timing ranges, voltage rating, and installation ease make it a popular choice for engineers and technicians. By understanding the principles of time delay relays and the FS127 in particular, engineers and technicians alike can gain a greater understanding of how to use these devices for their various applications.
