Multifunction time relays are particularly accurate in reaching the time limit even over long periods of time. With the universal supply of 12…240V AC/DC and different functions it is possible to find solutions even to the most challenging problems.
The brain chip of your application-specific miniature controller is the ideal solution for realizing custom control applications within minimum space at low-cost.
Time functions available in the MTR17-A07-U240-208 relay:
|
ON delay (TA) – on applying the supply voltage U the set interval T begins – off-delay of the output relay R. After the interval T has lapsed, the output relay R switches on and remains on until supply voltage U is interrupted. |
|
ON for the set interval (TB) – on applying the supply voltage U immediately switches the output relay R on for the set interval T. After the interval T has lapsed, the output relay R
switches off. |
|
Symmetrical cyclical operation pause first (TC) – applying the supply voltage U starts the cyclical operation from the T interval – switching the output relay R off followed by switching on the output relay R for the interval T. The cyclical operation lasts until the supply voltage U is interrupted. |
|
Symmetrical cyclical operation pulse first (TD) – applying the supply voltage U starts the cyclical operation from switching on the output relay R for the set interval T. After the interval T has lapsed, the output relay R switches off for the interval T. The cyclical operation lasts until the supply voltage U is interrupted. |
|
OFF delay with the control contact S (TF) – the input of the time relay is supplied with voltage U continuously. Closing of the control contact S immediately switches on the output relay R. Opening of the control contact S starts the set time of the delayed switching off of the output relay R. After the interval T has lapsed, the output relay R switches off. If the control contact S is closed during the interval T, the already measured time is reset, and the output relay R is switched on again. The OFF delay of the output relay R will start when the control contact S is opened again. |
|
Single shot for the set interval triggered by closing of the control contact (TG) – single shot for the set interval triggered by closing of the control contact (TG) – The input of the time relay is supplied with voltage U continuously. Closing of the control contact S immediately switches the output relay R on for the set interval T. After the interval T has lapsed, the output relay R is switched off. In the course of the interval T, any opening of the control contact S does not affect the function to be performed. The output relay R may be switched on again for the set interval, after the interval T has lapsed, by closing the control contact S again. |
|
ON for the set interval triggered with the control contact S (TI) -the input of the time relay is supplied with voltage U continuously. Closing of the control contact S does not start the interval T, and it does not change the position of the output relay R. Opening of the control contact S immediately switches on the output relay R for the set time. After the interval T has lapsed, the output relay R switches off. Opening and closing of the control contact S in the course of the interval T does not affect the function to be performed. The output relay R may be switched on again for the set interval with another closing and opening of the control contact S. |
|
ON and OFF delay with the control contact (TJ) – – The input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the interval T – on-delay of the output relay R. After the interval T has lapsed, the output relay R switches on. Opening of the control contact S begins further measurement of the interval T – off-delay of the output relay R, and after the interval has lapsed, the output relay switches off. In case the time for which the control contact S is closed in the course of measurement of the on-delay of the output relay R is shorter than the set interval T, the output relay R will switch on after the set interval T, and the output relay R will remain in on position for the interval T. When the output relay R is in on position, closing of the control contact S does not affect the function to be performed. |
