RDT

The RDT series is a range of relays with electronic time delay on pick-up or drop-out, consisting of 6 models with 4 change-over contacts, 10 A (nominal). These relays are created by assembling the electromechanical units of the RDM series with a digital electronic circuit.

Highly reliable electronic circuit, assembled using a small number of selected components and professional class products.

Programmable function (pick-up or drop-out), switching time selectable from 0.1s to more than 16 hours, with extreme precision over the entire scale and high resolution.

Models available with 4 timer contacts or with 2 timer contacts + 2 instantaneous contacts.

Knurled contacts to provide lower ohmic resistance thanks to the multiple electrical connection points: extended electrical life expectancy of the component, excellent performance for strongly inductive DC loads and for very low loads, such as in the case of interface signals. Optional magnetic arc blow-out for higher breaking capacity.

The excellent electrical and mechanical performance of these relays allows them to be used in the most demanding sectors, such as control and signalling functions in electricity generating stations, electrical transformer stations, rail transport, or in industries with continuous production processes.

High immunity to the electromagnetic interference typical of high voltage electricity distribution stations.
