Relé de protección para distribución secundaria

FANOX SIA-F

The SIA-F is an overcurrent and earth fault protection relay for secondary distribution with an auxiliary power supply of 24-230 Vac/dc.
4 current channels for conventional /1 and /5 current transformers.
Metal housing with high electromagnetic compatibility level (EMC) and a wide range of operating temperature.
Zone selection interlocking - ZSI (68 function) is available through conﬁgurable inputs and outputs thanks to the programmable logic (PGC).
To allow the communication, relays are provided with a local micro-USB front port and remote communication with different protocols on the rear side:
Rear Serial Port: Modbus RTU or DNP3.0 Serial (depending on model).
The SIA-F is provided with up to 2 conﬁgurable inputs and up to 3 configurable outputs (depending on the model).
The SIA-F is provided with non-volatile RAM memory to store up to 200 events and disturbance fault recording (DFR—4 fault reports and 1 oscillographic record in COMTRADE format). Thanks to its internal RTC (Real Time Clock), it maintains date and time.
The oscillography is downloaded by a communications port. The SICom communications program allows the oscillography record to be downloaded and saved in COMTRADE format (IEEE C37.111-1991).
