Description
Thanks to this adaptation, the SIA-B relays offer reduced dimensions, making this relay easy to install, and its lightweight helps the customer to save costs in transport.
SIA-B is suitable for RMUs, SF6 insulated, and compact switchgear in those installations where the space is critical, making the maintenance much more manageable.
USB front port connection (ModBus RTU protocol) for local communication. Remote communication through rear RS485 (ModBus RTU)
These transformers are also used to obtain current measurements with the advantage that SIAB relay can also be used with auxiliary power supply (24 Vdc, 110 Vac or 230 Vac). The equipment can be occasionally supplied by an external battery portable kit (KITCOM).
- Dual & Self powered OC&EF Protection Relay using the operating current through specific current transformers fitted on the lines. These CTs are also used to obtain current measurements.
- Stores up to 100 events and DFR (4 fault reports in data format) in non-volatile RAM memory without power supply thanks to its internal RTC (Real Time Clock).
- 1 input, LEDs and Configurable outputs thanks to Programmable Logic Control (PGC).
- Test menu allows the trip circuit to be tested before the transformation center is powered up.
- Bistable magnetic indicator which indicates the trip condition, maintaining its position even though the relay loses the supply (flag).
- Self diagnosis of the status (WATCHDOG) through led.
- Internal Commissioning battery as optional. (Lithium battery: 20 years lifetime).
- High electomagnetic compatibility (EMC).
- Low power consumption (0.5 W, 24 Vdc).
- In Self powered mode, SIA-B starts-up from 0.4 times of primary three phase current.
- USB front port connection (ModBus RTU protocol) for local communication. Remote communication through rear RS485 (ModBus RTU)
- Its compact size makes SIA-B really easy to install and its light weight helps the customer to save costs in transport.

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® Windows 7, Windows 8, Windows 8.1 and 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.
