The equipment has storage for up to 100 events, allowing any recorded incidents to be analyzed. All
SIA-B models are equipped with a real-time clock (RTC) which permits registering all the events with a
reliable timestamp.
Current measurements are performed using RMS values. Specific current transformers (CTs) are
used.
The equipment has a frontal communication port (mini USB). This port allows a PC to be connected,
which can be used to monitor the equipment using the SICom communications program (supplied by
FANOX). Besides, the frontal port can be used to power the equipment by using an USB cable which
can be directly connected with PC. Remote communication is available depending on model (RS485
rear port - Modbus RTU protocol).
The protective functions provided, easy-to-use interface, low amount of maintenance and simple
integration make the SIA-B a precise and practical solution for protecting both industrial and public
electrical grids and transformation and distribution centers. The main features of the equipment are
listed below, and these features will be explained in the rest of the manual:
