SIA-F
SIA-F protection relay is suitable to protect installations against O/C and E/F. Its compact size makes this relay adequate for installations where the space is critical. Optionally, other protection functions such as the thermal image (ANSI 49) the trip block for switch disconnector, and control functions as the monitorization of the CB (ANSI 52), The breaker failure (ANSI 50BF) can be included.
Besides, its special mechanic with the current transformers in charge of the measurement outside, allows the user to change the transformation ratio (by giving turnes through the holes of these current transformers.
The relay is designed to work with standard current transformers (1 A or 5 A of secondary) and is able to measure up to 30 times the nominal current. It is provided with local and rear communications, with optional protocols as Modbus RTU or DNP3.0 Serial.
Up to 3 outputs and 2 inputs are included in the relay to monitor and signal different situations in the installation.
The SIA-F is able to record up to 200 events, 4 fault reports, and 1 oscillographic record in non-volatile RAM memory with the date and time thanks to its internal real clock (RTC)
Thanks to its versatility and to its compact size, this relay can be used in a lot of applications.
Main Applications: Secondary Distribution, RMUs, and SF6 Insulated Switchgears

- The SIA-F is an overcurrent and earth fault for secondary distribution protection relay with universal auxiliary power supply 24-230 Vac/dc. The current measurement is obtained by standard current transformers /1 or /5.
- The relay can be also supplied by a USB cable connected to the laptop, with the USB KITCOM adapter or a standard power bank.
- Metallic box with high electromagnetic compatibility level (EMC) and wide range of operating temperature.
- To allow the communication, relays are provided with a local micro USB front port and with remote communication with different protocols on the rear side depending on model
- 1 RS485 Port: Modbus RTU
- 1 RS485 Port: DNP3.0 Serial
- The SIA-F has up to 2 configurable inputs and up to 3 configurable outputs (depending on model).
- The SIA-F is provided with non-volatile RAM memory in order to store up to 200 events and disturbance fault recording (DFR4 fault reports and 1 oscillographic record in COMTRADE format), maintaining date & time thanks to its internal RTC (real Time Clock):
- 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).

Communication Software for all Fanox Protection Relays MV Range
The SICom PC software has been designed and programmed to gain access to all of Fanox relays information, modify the settings and configuration, check states and measurements, and to analyse and save events and fault reports using a graphic-friendly user interface.
SICom software works with the Windows® Windows 7, Windows 8, Windows 8.1, and Windows 10 operating systems.

- Reading and changing counters
- Commands for opening and closing the circuit breaker and blocking/unblocking the recloser
- Configuration of the inputs
- Configuration of the outputs
- Configuration of the causes that start a Fault Report
The software update does not require any user´s action; if the computer is connected to the Internet, SICom updates itself when it is started.
It will allow you to prepare all the settings and relay configurations without having the relay connected to the PC (offline mode), reducing engineering and commissioning time.
SICom program uses Modbus protocol, so only the ports with this protocol can be used to establish the communication.
