A double motor sequential timer is a device used to control the sequential operation of two motors in an automated system or industrial process. It ensures that the motors operate one after the other in a specific sequence, following a predefined time delay between their activation.
This type of timer typically consists of two main components:
1. Circuit: The control circuit is the brain of the timer and is responsible for managing the timing and sequencing of the motors. It usually includes a microcontroller or a programmable logic controller (PLC) that can be programmed to control the motors based on the desired sequence and timing requirements.
2. Relays or Motor Drivers: The control circuit interacts with relays or motor drivers to switch the power supply to the motors on and off. The timer activates the appropriate relay or motor driver to start the first motor and, after the specified time delay, activates the second motor while deactivating the first one.
The sequence of operations could vary depending on the application. For example, in a pumping system, the timer may be set to start a primary pump first and then, after a delay, start a secondary pump. In industrial automation, such timers are often used in conveyor systems or manufacturing processes where precise sequencing is required.
It's worth noting that while the term "double motor sequential timer" is not a standard industry term, the concept described above is commonly used in industrial control systems. Depending on the complexity of the application, the timer may have additional features such as manual overrides, adjustable timing intervals, and safety interlocks.
For more specific information about a particular timer model or implementation, it's best to refer to the product documentation or consult with an industrial automation specialist or electrical engineer.
