SIA-F – SF6 & Metalclad Switchgear Protection Relay

SIA-F protection relay is suitable to protect installations against O/C and E/F. Its compact size makes this relay adequate for installition where the space is critical. Optionally, other protection functions 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, allow the user to change the transformation ratio (by giving turnes throgh 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 oscillografic records 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

Features

The SIA-F is an overcurrent protection relay with a switched auxiliary power supply (24-220 Vdc / 48-230 Vac). The current is measured by using /5 or /1 current transformers. The relay can be also power supplied by a USB cable connected to the laptop or an standard power bank.

Protection functions: 50, 50/51, 50N/G, 50/51 N/G, CLP, 86, PLC.
Trip block for switch disconnector, 49, 49T, 52, 50BF, 68 as optionals.
High electromagnetic compatibility.
With circuit breaker control and monitoring (circuit breaker status, number of openings, accumulated amperes, etc.).
Compact size with reduced depth makes it easier to install and saves costs.
USB connection on the front (Modbus RTU communication protocol).
A specific test menu is provided.
There are three configurable LED indicators on the front of the SIA-F equipment. By default, they indicate indicate if the equipment is On (LED ON), if an alarm has happened (LED ALARM) or if a trip has happened (LED TRIP).
Programmable logic (PLC)
1 Oscillographic record, non-volatile RAM memory in order to store up to 200 events and 4 fault reports, without power supply thanks to its internal RTC (Real Time Clock)

Software

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.

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.
