Detailed information on the Italian DOSSENA alarm signal relay:

The new generation RECA/E alarm signal relay (electromagnetic type) of Italian DOSSENA is developed using technology. In addition to the basic functions of previous equipment, it also adds more practical functions, such as widescreen high brightness digital display, multiple language options, internal self check, and so on. And with reliable performance, wide range of applications, and excellent quality, DOSSENA has always demonstrated its commitment to quality since its establishment fifty years ago.
This relay is currently a technology in the global market and can be installed on all devices that require monitoring of machines or electronic systemsCompact structure, simple operation, easy to use, high cost-effectiveness.
Its function is to:
1. Through temperature and pressure sensors, RECA/E can have alarms of different priority levels
2. By displaying information in specific colors, it can be instantly identified.
3. * Priority alarm (* alarms among multiple alarms) function.
4. RECA/E has a self powered electronic memory function, which can display different colors according to alarms in manual mode.
Even if there is a power outage, the alarm can still be stored.
6. The relay is equipped with a self diagnostic function, which can report the operating status or abnormal operation.
7. The serial port output RS485 allows relays to communicate with the Multilog data logger, and without the need for any software, the alarm events of each relay can be stored as historical records.

Advantages of RECA/E alarm signal relay:
1. Wide screen high brightness dot matrix display
2. The operation interface is user-friendly and can change colors according to the working status of the instrument.
3. Auxiliary voltage can be AC or DC.
4. High tech internal self diagnostic system that can be displayed on the screen.
5. According to user needs, the alarm level can be selected.
6. It can be remotely connected to a data logger (Multilog) through an Ethernet port.
7, 4 relay outputs
8. Each relay has 4 or 8 alarms
9. Alarm output can be selected (NO-NC or NC/NO)
10. Multiple languages: English, Italian, French, Spanish
11. Serial port output RS485
12. Size: 96 * 96 * 51

The problem with most electronic and electrical mechanical protections is that the alarm signal is disconnected when the auxiliary voltage drops. In most cases, this is very important to avoid starting damaged machines. The alarm signal relay equipped with CMOS electronic system can store information related to the signal part even when the voltage drops. The electromagnetic indicator on the panel can provide relevant information on the number of alarm signals. Another important feature of this alarm signal relay is that it can withstand sudden overvoltage that occurs on the input alarm very well. Due to the combination of mechanical signals with automatic/manual signal relays and alarm relays, RECA relays greatly enhance the functionality of traditional alarm signal relays.
