Time relay MTR17-TTS-U240-208 equipped with universal power supply can be connected to any AC/DC voltage source in range of 12…240V. Performs TS 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-TTS-U240-208 relay:
 |
ON delay and ON for the set time with closing of the control contact S (TS) – the input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the interval T1, and after the interval has lapsed, the output relay R switches on for the interval T2. Following the interval T2, the output relay switches off, and the circuits awaits for the control contact S to be closed again. In the course of the intervals T1 and T2 the position of the control contact S is of no importance. |
