TDBE4-U/ relay - Delay-on & delay-off, 4 pole - Mors Smitt railway components & solutionsRelated Contents. A timer is a control device that outputs a signal at a preset time after an input signal is received. The pointers on the Timer do not move along with time like the hands of a clock do. You cannot see the progression of time. Therefore, two operation indicators are provided on the upper left of the Timer to identify the timer status. Run indicator: Indicates whether the time is being measured or the time has reached. Power indicator: Indicates whether power is being supplied to the Timer.
Understanding Time Delay Relay Functions
Wednesday: July 10, : Time Delay Relays. Understanding the differences between all the functions available in time delay relays can sometimes be a daunting task. When designing circuits using time delay relays, questions such as what initiates a time delay relay, does the timing start with the application or release of voltage, when is the output relay energized, etc. Time delay relays are simply control relays with a time delay built in. Their purpose is to control an event based on time.

When Dayton timer reaches end of countdown, circuit going to Load is turned OFF Momentary on switch can be any circuit.
Time relays are used in control switching operations involving time delay. Most of these time relays have multiple time setting ranges and most of them are explained below. Time relays perform either on-delay or off-delay timing. An arrow is used to denote the function of the timer. An arrow pointing up indicates an on-delay timing action, while an arrow pointing down indicates an off-delay timing action.
Description Plug-in electronic railway timer relay with delay-on and delay-off function and three change-over contacts and one normally-closed contact.
