Time Delay Relays form an essential element of almost any electrical system used today. The 88857701 relay is a special type of time delay relay that is designed to activate after a specified amount of time has elapsed. By continuously monitoring a specific electrical system or signal, these relays can detect changes in the system and take appropriate action in order to respond accordingly. The 88857701 time delay relay can be used to achieve a number of different objectives, ranging from controlling simple lighting systems to complex industrial processes.

Application Field

The 88857701 is an ideal solution for controlling the various functions and operations of an electrical system. It could be used to activate lights, fans, pumps, valves, and motors, thereby ensuring the smooth operation of these components. Additionally, it can be used to activate alarms or safety devices when certain conditions are met. The 88857701 is also commonly used in a wide range of industrial applications, such as controlling the production process of a factory or ensuring that the temperature of a room is kept at a certain level.

The 88857701 time delay relay is also suitable for use in the automotive industry, where it can be used to ensure that the fuel injection system of a car runs at an optimum level and delivers the necessary performance. The 88857701 can be used for a variety of other purposes, including the automatic switching of circuits, the timing of motors, and the sequencing of operations in industrial processes.

Working Principle

The 88857701 time delay relay utilizes two main components in order to achieve its objective; the main contacts and the timer contacts. The main contacts provide the main control for a signal or electrical system, while the timer contacts are designed to activate after the specified delay time has elapsed. To provide a clear illustration of the working principle of the 88857701, let us examine a common application where the 88857701 time delay relay is used to sequence a motor.

A motor needs to be started and then stopped after a predetermined amount of time. In this scenario, two 88857701 time delay relays would be used. The first relay will have its main contact connected to the motor’s power supply, while its timer contacts are connected to the motor’s start switch. When the power supply to the motor is turned on, the first relay is energized and its timer contacts will activate after the set delay time. This will cause the motor to start. Once the motor starts running, the second 88857701 relay will be activated and its timer contacts will close after the elapsed time, effectively stopping the motor.

The 88857701 time delay relay is a versatile device that can be used in numerous applications. Its ability to accurately control the timing of signals or operations makes it an ideal choice for a variety of different scenarios. Additionally, its robust design makes it suitable for both industrial and consumer-based applications. All of these qualities make the 88857701 time delay relay an invaluable asset for a variety of different tasks.
