Sequence Relay with Alarm

The SACI sequence relay with alarm allows you to visualise correctly with lights if there is any anomaly in any of the phases and early detection possible drawbacks in the equipment.

• Reversing engines.
• Underperformance of the engines.
• Overheating and ultimately engine failure.
• Excessive and abnormal noises of the equipment, as well as strange vibrations.

What is the SACI sequencer like?

There are different types of sequence meters on the market to check the voltages of the three phases. Some of them have a built-in display to show the information, but this sequencer in our catalogue is equipped with lights that indicate whether the sequence is correct or incorrect, so that it can be used to check the voltage of the three phases. is analogue.

The SACI sequencer allows you to monitor and protect your electrical systems by letting you know if the phase sequence of three-phase systems is correct. If this is not the case, it will generate a alarm signal.

The SACI sequence relay with alarm is also equipped with a built-in relay which, if it detects that the phases do not occur in the correct way, disconnect the load to prevent damage to the connected equipment.

Finally, this sequencer is panel mounted, i.e, fixed. It must therefore be installed in switchboards or control panels.

Benefits of analogue sequencers

While digital sequencers are always a good choice because of their accuracy and versatility, analogue sequencers have other attractive features.

On the one hand, they tend to last longer because they are more robust because the mechanical components are more resistant to shock and temperature variations. This makes this sequencemeter a perfect choice for demanding industrial environments.

Analogs, on the other hand, tend to be more economical, especially if we are talking about a basic model like this one, which, in addition, consumes less energy.

On the other hand, it is very easy to understand, The operation is very intuitive. This one, in particular, works with a simple light system and is very suitable for industrial environments where operators are not familiar with this type of device, as they will quickly grasp how it works.

How does our sequencer work?

This sequence relay with alarm first measures the voltage of the three phases without the need for an auxiliary power supply. It then compares them with each other and determines the order in which each phase reaches its maximum value. If the analysed values do not match the expected values, the alarm signal is generated and then the relay is activated, which disconnects the load to protect the equipment.

How to install the SACI sequencer?

It is important to note that follow the manufacturer's instructions is not enough for this type of device, in this case basic electrical knowledge is required to install our sequencer. Normally and in general, these are the steps to install it:

• Power off.
• Attachment of the sequencer to the panel.
• Connection of conductors
• Sequencer configuration
• Switching on the power supply

Why use the SACI sequence relay with alarm in your installations?

• You can visit prevent damage to your engines automatically disconnecting them if the three-phase sequence is incorrect. The same applies to the electrical installation.
• Your equipment will be more secure for workers, as well as your industrial processes.

Does it require a lot of maintenance?

The maintenance of this device is minimal and only needs to be periodically checked for safe connections and correct operation. In this regard, it is also recommended that the sequencer be kept as clean and dust-free as possible.
