TD

The TD series is a range of CURRENT MONITORING instantaneous relays created by assembling the electromechanical units of the RDM series with a digital electronic circuit.

Can be supplied for currents from 40 mA to 5 A, AC or DC.

These relays must be wired in series with a circuit and used to detect the status of a load when under power. One specific application for this series of relays is the control of obstruction warning lights (obstructions on land, in the air, at sea, navigation lights) where high levels of reliability and efficiency are indispensable factors in ensuring safety. These components are suitable both for general current monitoring purposes, and for specific types of warning light signals having different electrical specifications and response characteristics.

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 typical application sectors are among the most demanding, such as electricity generating stations, electrical transformer stations, fixed equipment for railways, or industries using continuous production processes (chemical and petrochemical, rolling mills, cement works, etc.).
