Description

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

- Industries with continuous production processes.

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