Dual function Time Relay MTR17-TAB-U240-116

  • TA or TB function
  • 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-TAB-U240-116 equipped with universal power supply can be connected to any AC/DC voltage source in range of 12…240V. Performs TA or TB function (selected by S contact state) with time 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-TAB-U240-116 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.
To execute TA function the S contact must be floating.
ON for the set interval (TB) – 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.
To execute TB function the S contact must be connected to A1.
