Time Relay MTR17-TXY-U240-116

  • TX or TY function
  • Two independently controlled times T1 and T2
  • 7 time rangers 1s … 100h
  • Wide range power supply of 12…240V AC/DC
  • 1NO/NC 16A contact arrangement
  • Low power consumption – <2.5 VA or <2 W – high energy efficiency
  • Installation design DIN 35mm
  • 17.5mm width

Time relay MTR17-TXY-U240-116 equipped with universal power supply can be connected to any AC/DC voltage source in range of 12…240V. Performs TX or TY function (selected by S contact state) 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-TXY-U240-116 relay:

Cyclic operation with two independent intervals T1 and T2 (TX) – the function turns the Relay ON for T1 and then turns OFF for T2. The cycle is repeated infinitely.
To perform TX function, the control contact S must be permanently activated (connected to A1).
Cyclic operation with two independent intervals T1 and T2 (TY) – the function turns the Relay OFF for T1 and then turns ON for T2. The cycle is repeated infinitely.
To perform TY function, the control contact S must be permanently deactivated (left floating or connected to A2).
