ON delay and OFF delay with control contact S – time relay MTR17-TTQ-U240-xxx

Time relays MTR17-TTQ-U240-116 or MTR17-TTQ-U240-208 with independently controlled times T1 and T2 ( 7 time ranges are particularly accurate in reaching the time limit even over long periods of time). With the universal supply of 12V AC/DC to 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.
Supply diode: it is lit permanently when the time is not being measured. In course of the T1 time measurement, it flashes at 500 ms period where it is lit for 80% of the time, and off for 20% of the time. For the T2 time, the period is 250 ms.
Adjustment of the set values: the values of time and range are read in the course of the relay’s operation. The set values may be modified at any moment.
Release – the relay is released by connection of the S contact to the A1 line. For DC supply, the positive pole must be connected to the A1 line. The level of the S contact activation is adjusted automatically depending on the supply voltage.
Relays are designed for direct mounting on 35 mm rail mount acc. to PN-EN 60715. Operational position – any. Connections: max. cross section of the cables: 1 x 2,5 mm2 / 2 x 1,5 mm2 (1 x 14 / 2 x 16 AWG), length of the cable deinsulation: 6,5 mm, max. tightening.
Supply: the relay may be supplied with DC voltage or AC voltage 48…63 Hz of 9,6…264 V. A programmed control of the supply voltage has been applied so the processor shall not start operation if the voltage is lower than approximately 9 V. The supply voltage is permanently monitored in course of the operation of the relay. When the voltage drops below 9 V for more than 50 ms, the relay shall be reset. Owing to this, the regeneration time is programmed to 50 ms, and it does not depend on the tolerance of the elements.

ON delay and OFF delay with control contact S. Independent T1 and T2 settings (TQ) – the input of the time relay is supplied with voltage U continuously. Closing of the control contact S starts the interval T1, and after it has lapsed, the output relay R switches on. Opening of the control contact S starts the interval T2, and after it has lapsed, the output relay R switches off. In case the control contact S is closed in the course of the interval T2, the measured time is reset and the output relay R remains switched on. In case the control contact S is closed for time shorter than T1, the unit will not switch the output relay R on.
