Main hardware characteristics of the electronic device

The hardware structure of this periphery is based on the adoption of extremely new CPU
CMOS with 32 bits developed specifically for the execution of the so-called “embedded”
applications.
The card uses an EEPROM to store the Set-up data and flash memories for storage of the
archives of historical data and LOG files of events.

Data Sheet

The Card has 1 RS485 gate for sensors and 1 RS485 gate (opto-isolated) for local networks
used for connections with local communication devices (configuration computer, terminals
and remote controls etc).
The card integrates a Real Time Clock (clock with date) that allows the software to storage
figures in a chronological order.

The device has been designed to be fitted onto a panel, and is built with IP66
protection panel.
