Multifunctional time delay relays

REV-201M multifunctional time relay

The REV-201M two-channel time relay with a delay-on-make feature is designed to switch 220V/50Hz AC electric circuits and 24 - 100V DC electrical circuits with an adjustable time delay-on-make from 0 to 36000 sec.

The REV-201M two-channel time relay with a delay-on-make feature is designed to switch 220V/50Hz AC electric circuits and 24 – 100V DC electrical circuits with an adjustable time delay-on-make from 0 to 36000 sec. 

 

 

The relay has two channels and can operate under four operation algorithms set by the user:

 

 

  • make delay relay;

 

  • pulse relay;

 

  • periodic (cyclic) relay;

 

  • control relay.

 

 

The algorithm is set by the A position of switches. 

 

 

With corresponding connection diagrams the device 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 time intervals adjustment is performed by a pair of potentiometers and a limit switching block for each channel separately.

 

 

The front panel features for each channel a double-color LED with the following algorithm:

 

 

  • green glow – voltage is present on the channel;

 

  • red glow – load relay is on.

 

 

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.
