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 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.
