Time Delay Relays

Product Details:

The time delay relay REV-114 is the microprocessor-based device intended to control the load with independent time delay. It provides the certain sequence of the load operation according to the mode specified by the user.

REV-114 is equipped with control buttons and a digital display designed for adjustment and visual check of timing.

REV-114 can be operated by seventeen operation algorithms:

• on-delay;

• time delay when energizing;

• periodic with on-delay;

• periodic with time delay when energizing;

• pulse generator;

• on-delay with external start;

• off delay with external start;

• pulse I with external start;

• pulse II with external start;

• on/off delay with external start;

• pitch of the load relay (during each control contact closing);

• periodic with external start and on-delay;

• periodic with external start and time delay when energizing;

• pulse generator with external start;

• start stop;

• always ON;

• always OFF.

Product Details:

The time delay relay REV-120 is a microprocessor based device intended for on/off switching the load in user defined time intervals.

REV-120 can be operated by ten operation modes:

• on-delay;

• time delay when energizing;

• periodic with on-delay;

• periodic with time delay when energizing;

• off-delay (when control contact opening);

• pulse I (when control contact closing);

• pulse II (when control contact opening);

• on/off delay (according to control contact);

• pitch of the load relay (during each control contact closing);

• pulse generator of 0.5 s;

• selectable time range from 0.1 s to 1 hour.

Product Details:

REV-201M is designed for the commutation of electrical circuits of 240V 50Hz AC as well as 24 – 100V DC electrical circuits with the adjustable time delay setting.

The relay has two channels and can be operated by one of seven operation algorithms that the user specifies:

- Turn ON time delay relay;

- Pulse relay 1; 

- Intermittent relay 1;

- Operation relay (star-delta);

- Pulse relay 2;

- Intermittent relay 2;

- Off-delay relay.

 

* REV-201M could be used as the relay of pre-starting signalization for the machinery that require to announce that some mechanism or machinery will soon take a start to make people aware of this and get away from the risky zones. Widely used for steel plants, heavy machinery, cranes and construction mechanisms as well as mining companies for the technological stuff safety.

The operation logic algorithm can be selected by the A position DIP switch. The device has 7 selectable time range set by the D1 and D2 DIP switches.

Time delay setting for each channel starts from the moment of the power supply given to the corresponding channel. REV-201M allows to provide 2 modes of operation:

Mode 1. Independent operation of channels. To each of two channels power supply is given independently and thus each channel starts the countdown from the moment the power supply is given. This is the mode when 2 independent time relays are functioning in one compact case housing (2 time delay relays in one case).

Mode 2. Parallel operation of the channels. To each of two channels the power supply is applied simultaneously. Thus, the time countdown on each channel starts at the same time and comes one and the same input power supply. Triggering time corresponds to the user-adjusted settings for each of the channels. So the REV-201M in this mode operates like one time delay relay with 2 output contacts that have the same or different time settings.

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
