Time relay MTR17-TTT-U240-208 equipped with universal power supply can be connected to any AC/DC voltage source in range of 12…240V. Performs TT function with T1 and T2 times independently adjustable in range of 100ms to 100h. Microcontroller based circuit ensures high stability of time counter.
Designed to use in industrial automation systems.
Time functions available in the MTR17-TTT-U240-208 relay:
 |
ON for the set intervals T1 and T2 with the control contact S (TT) – the input of the time relay is supplied with voltage U continuously. Closing of the control contact S switches the output relay R for the interval T1, and after the interval has lapsed, the relay R is switched off. Opening of the control contact S switches on the output relay R for the interval T2. If the control contact S is open when the interval T1 lapses, the output relay R will remain on for the interval T2. If the control contact S is closed when the interval T2 lapses, the output relay R will remain on for the interval T1. |
