Time relay MTR17-TTR-U240-208 equipped with universal power supply can be connected to any AC/DC voltage source in range of 12…240V. Performs TR 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-TTR-U240-208 relay:
 |
OFF delay and breaking time delay with opening of the control contact S; independent settings of T1 and T2 intervals (TR) – the input of the time relay is supplied with voltage U continuously. Closing of the control contact S switches on the output relay R. Opening of the control contact S starts the interval T1, and after the interval has lapsed, the output relay R switches off for the interval T2. Following the interval T2, the output relay R will be switched on again when the control contact S is closed on the lapse of the interval. In the course of the intervals T1 and T2 the position of the control contact S is of no importance. |
