Description
The SIU-C represents the best and most precise protection solution for transformers and electrical machines, in high, medium, and low-voltage distribution systems. The SIU-C is a voltage and frequency protection relay and also protects decoupling, load shedding, and loss of main (islanding), universal with an auxiliary power supply of 24-230 Vdc/ac.
Notable for the capability of measuring up to 1.000 volts when it is connected directly to the low-voltage line. Voltage measurement: 5 voltage channels for conventional.
To allow the communication, relays are provided with a local micro USB front port and with remote communication with different options ports and protocols; Rear RS485 Port: IEC60870-5-103, Modbus RTU, or DNP3.0 Serial. RJ45 Port: Modbus TCP/IP, DNP3.0 TCP/IP or IEC60870-5-104 + Web Server + SNTP Protocol.
The SIU-C is provided with 11 configurable inputs and 5 configurable outputs. It is provided with non-volatile RAM memory in order to store up to 3072 events and disturbance fault recording (DFR), maintaining date & time thanks to its internal RTC (real Time Clock).
Fanox counts, with its own SICom Communications Program, allows the oscillography record to be downloaded and saved in COMTRADE format (IEEE C37.111-1991)

- The SIU-C is a voltage and frequency protection relay for transformers and electrical machines, in high, medium, and low voltage distribution systems. Also protects decoupling, load shedding, and loss of main (islanding), universal with auxiliary the power supply of 24-230 Vdc/ac.
- Voltage measurement: 5 voltage channels for conventional VTs.
- The capability of measuring up to 1.000 volts when it is connected directly to the low voltage line.
- Metallic box with high electromagnetic compatibility level (EMC) and a wide range of operating temperatures.
- Protection of decoupling, load shedding, and loss of main (islanding). Loss of Main (islanding) occurs when part of the public utility network loses connection with the rest of the system. If this situation is not detected, then the generator could remain connected, causing a safety hazard within the network. Automatic reconnection of the generator to the network may occur causing damage to the generator and the network. SIU-C protection relay detects this situation thanks to its voltage and frequency functions focused on the Rate of change of frequency (ROCOF) method.
- Signaling/control of the circuit breaker (52 function) and the recloser (79 function).
- To allow the communication, relays are provided with a local micro USB front port and with remote communication with different options (ports and protocols) on the rear side:

- SIU-C is provided with non-volatile RAM memory in order to store up to 3072 events and disturbance fault recording (DFR), maintaining date & time thanks to its internal RTC (Real Time Clock).
- 5 records in data and COMTRADE format (300 cycles each record): 1 to 8 pre-fault cycles + 292 to 299 postfault cycles.

Communication Software for SIA & SIL protection relays
The SICom PC software has been designed and programmed to gain access to all of Fanox relays information, to 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®7, Windows®8, Windows®8.1 y Windows®10 operating system.
- General data reading: Complete model, Version, Serial number, etc.
- States reading
- Measurements reading
- Reading and changing settings
- Reading and changing configuration
- Reading and deleting events
- Reading and deleting fault reports
- Reading and deleting demand current (load data profiling)
- Reading and saving oscillographic records in Comtrade format
- Changing the user passwords
- Saving and Loading settings files
- Saving and Loading configuration files
- Saving events and fault reports
- Saving demand current (load data profiling)
- Date-time synchronization
- Configuring the communication parameters
- Reading and changing counters
- Commands for opening and closing the circuit breaker and block/unblock the recloser
- Configuration of the inputs
- Configuration of the outputs
- Configuration of the causes that start a Fault Report
The update of the software does not require any user´s action, this is, if the computer is connected to 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.
