Multifunctional time delay relays

REV-201 two-channel timing relay

REV-201 two-channel delay-on-make time relay is designed to switch 220V/50Hz AC electric circuits and 24 - 100V DC electric circuits with an adjustable time delay from 0 to 220 sec.

REV-201 two-channel delay-on-make time relay is designed to switch 220V/50Hz AC electric circuits and 24 – 100V DC electric circuits with an adjustable time delay from 0 to 220 sec. 

 

 

The device consists of two independent time relays (two channels). Each channel’s time delay countdown begins when the corresponding channel is energized.

 

 

With corresponding connection diagrams, the REV-201 relay allows for implementing the following:

 

 

  • independent channel operation (the time delay count begins when each individual channel is energized);

 

  • parallel channel operation (both channels are energized simultaneously).

 

 

The make delay for each channel is set separately. Each channel features two settings: from 0 to 20 sec and from 0 to 200 sec, and the channel on-make delay consists of the sum of the delays set by two potentiometers. 

 

 

Green LED of each corresponding channel indicates presence of the channel voltage. Red LED indicates the channel tripping.

 

 

Each channel’s output is equipped with one normally closed contact and one normally open contact. 

 

 

The relay power circuit is galvanically isolated from the output circuits.
