Time Delay Relays are electric devices used to control the timing of electrical switches, and 1472987-1 is a type of Time Delay Relay. Generally, they feature self-contained microprocessor or analogue circuits that perform timing functions within a typical range of 0.001 to 10,000 seconds and are often used for time-lapsed events, such as temperature control, active power factor correction, security systems and motor control.

Application Field

1472987-1 devices can be widely used in different industry, from nuclear power plants, chemical production, air conditioning and ventilation system, fire regulation, etc. In fact, this type of time delay relay can be used for a wide variety of applications. Some common applications in industry that rely on time delay relays include:

• Activating and deactivating equipment - Common applications include starting and stopping motors or other pieces of equipment at specified intervals or specific times.
• Maintaining temperatures - The time delay relays can help maintain certain temperatures in a room as precisely as needed, resetting the thermostat or controlling a ventilation system when necessary.
• Sequencing equipment - Time delay relays are typically used in sequencing applications, with the relay serving as a “memory” that can remember and reset a specific sequence of events.
• Safety concerns - Relays can be used to activate and deactivate safety devices, such as emergency shutoffs or warning signals.

Working Principle

Time delay relays can be both mechanical and electrical in nature. Mechanical time delay relays rely on the mechanical properties of gears, gravity, or inertia to operate. In electrical time delay relays, the delay times are usually between 0.05 second to 10,000 seconds. For 1472987-1 time delay relays, its working principle is based on analog or digital circuit. With built-in circuits and software programming, the digital timer relays offer longer delay time for applications.

The 1472987-1 type time delay relay works using a timer circuit that is made up of an integrated circuit providing the delay time, a voltage source to power the circuit, and a switch to activate the circuit. When the time delay relay is activated, the timer begins counting down until zero and then triggers the switch to close or open. The amount of time the timer takes to reach zero is determined by a fixed resistor, a variable resistor, or a capacitor.

The 1472987-1 type time delay relay can be programmed to activate as soon as the relay receives power, and it can also be set to activate at a certain predetermined time of day. This makes it a versatile tool for systems controllers, as they can be used to control when the system should turn on and off. Additionally, they can be used to control a system’s behavior at predetermined intervals, such as every five minutes or every hour.

Time delay relays are powerful and versatile tools and can be used in both automated and manual operation processes. The 1472987-1 type time delay relay is a reliable tool that is designed to last a long time and can provide accurate and reliable performance.
