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-B07-U240-116 relay:

Single shot leading and single shot trailing edge with control input (TM)
– the supply voltage U must be constantly applied to the device. When the control contact S is closed, the output relay R switches into on-position and the set interval t begins. After the interval t has expired, the output relay R switches into off-position. If the control contact S is opened, the output relay R switches into on-position again and the set interval T begins (green LED U flashes). After the interval t has expired the output relay R switches into off-position (yellow LED not illuminated). During the interval, the control contact S can be operated any number of times.
OFF delay with the control contact S, without extension of the interval T (TE)
– 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. Opening or closing of the control contact S within the interval T does not affect the function to be performed.
ON for the set interval by closing the control contact S, with extension of the interval T – extension of the time of switching on the output relay R (TH)
– 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. The next closing of the control contact S immediately
switches on the output relay R for the interval T. In case the control contact S is closed within the interval T, the measured time is cancelled, and the interval T starts again.
ON delay with the control contact S without the interval T extension (TN)
– 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 and remains in this position until the control contact S is closed again, which instantly switches the output relay off for the time T, and after the interval T has lapsed, the output relay R switches on again. In the course of measurement of the interval T, opening or closing of the control contact S does not affect the status of the output relay R. The output relay R may be switched on again after the current cycle has been completed.
ON delay with closing of the control contact, with the interval T extended (TO) – the input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the interval T, and after the interval T has lapsed, the output relay R switches on and remains in this position until the control contact S is closed again or until the supply voltage U is interrupted. Closing of the control contact S resets the thus far measured time and starts the new interval T.
ON for the set interval controlled by closing of the control contact S, with the function of switching off the output relay R prior to the lapse of the interval T (TL) – 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. Any next closing of the control contact S switches on the output relay R again. In case the control contact S is closed again during the interval T, the output relay is immediately switched off, and the measured interval is cancelled. In the course of the interval T, any opening of the control contact S does not affect the function to be performed.
Bistable operation with the control contact S (BA) – the input of the time relay is supplied with U voltage continuously. Closing of the control contact S immediately switches on the output relay R. Each next closing of the control contact S results in a change of the status of the output relay R to an opposite one (the feature of a bistable relay).
