Time relay MTR17-TCD-U240-116 equipped with universal power supply can be connected to any AC/DC voltage source in range of 12…240V. Performs TC or TD 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-TCD-U240-116 relay:
|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.
To execute TC function the S contact must be floating.
|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.
To execute TD function the S contact must be connected to A1.
