RDT.15 relays are delay-on-drop-out devices, with a capacitor wired in parallel with the coil. These relays do not require an auxiliary power supply during the time delay interval. The delay time is fixed (non-adjustable) and factory-set.
RDT.16 relays are delay-on-drop-out devices, with a capacitor wired in parallel with the coil. These relays do not require an auxiliary power supply during the time delay interval. The delay time is adjustable from 0.1 to 6 seconds.
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
The typical application sectors are among the most demanding, such as:
- Electricity generating station
- Electrical transformer stations
- Fixed equipment for railways
- Industries using continuous production processes (chemical and petrochemical, rolling mills, cement works, etc.)
