UTMR

The UTM unit is a static timer module, designed for applications requiring a time delay activated on pick-up (UTME) or on drop-out (UTMR). This units can be used to drive an external instantaneous relay that requires a time delay. There are 2 outputs available: one timed and the other instantaneous, with maximum rated power 6W.

The UTM unit offers high reliability, thanks to the use of an electronic circuit requiring a small number of components, and to the selection of professional grade products.

Time-delay on drop-out, switching time selectable from 0.1s to more than 9 hours, with extreme precision over the entire scale and high resolution. Two dip switch selectors for user adjustments.

The electronic circuit features high immunity to the electromagnetic interference typically associated with high voltage electricity distribution stations. The construction of the module and careful choice of materials are such that they ensure long life and considerable ruggedness, even in harsh operating environments and when subject to strong thermal shocks.
