
Conventional remote control (telemechanics) by wired circuits for receiving/transmitting
signals (via terminal inputs/outputs) as an alternative to communication channels.

Operation of substations switchgear with SF6 and enclosed switchgears (support of relief
vents).

Measurements of true RMS values for 12 analog voltage and current signals, power coefficient
tg

or cos

and derivative values: frequency, active/reactive power and selected type of
energy (including subdivision into day-time zones) and admittance, conductance and
susceptance of earth fault branch (conditionally, when U0>U0n is satisfied), based on calculated
RMS values.

Up to 4 banks for main se 1 bank for auxiliary settings (for transmission channels set-
points purposes).

Event log recorder which can save 1024 reports (stored in non-volatile memory) , each day and
time-stamped with resolution up to 100us, event code as protocol index (e.g. DNP3), and user
definable description.

Data recorder (DAR) which records recent samples in an active circular buffer; in a standard
version, buffer memory can be organized in one of the following buffer configurations: 2 *
20.48s (ie. 2 buffers, each of 20.48s) , 4 * 10.24s, 8 * 5.12s, 16 * 2.56s, 32 * 1.28s, 2 * 40.96s, 4 *
20.48s, 8 * 10.24s, 16 * 5.12s or 32 * 2.56s.
There are always
10 electrical quantities recorded in each buffer.
→ Example: configuration with CT-0 + VT-0:
• Voltage U12
• Current I1
• Voltage U23 • Current I2
• Voltage U31 • Current I3
• Voltage U0 • Current I0
• Input AUXI0 (VT) • Current Ig
and 96 digital values (states of functors).
For IF-4 modules, the range of buffer configuration is extended by the following settings:
2 * 81.92 s, 4 * 40.96 s, 8 * 20.48 s, 16 * 10.24 s and 32 * 5.12 s.
In addition, the IF-4 module (combined with MB-2/3) provides a data recorder operating at 3200
Hz (64 samples per period) and even a wider buffer configuration range and up to
192 digital
states to be recorded.

Criteria recorder (CDAR) – records up to 16 selectable RMS values in max. 32 buffers with
settable recording frequency.

Time synchronization acc. to IEEE 1588 PTP with a precision of 1 us with autonomic local
synchronization (if no supervisory system is present).

Operation together with a supervisory system via:
– two independent RS-485 links – to be selected with one of many transmission protocols:
uCZIPstd, uCZIPnet, DNP-3.0, IEC-60870-5-101, IEC-60870-5-103, CZIPstd (backward
compatibility), Modbus, CAN-PPM2, etc. It is possible to use optical fiber cables (FO);
– 10/100 Mb
Ethernet link – to be selected with TCP / UDP protocols (with protocol tunneling:
uCZIPstd, DNP-3.0, etc.) and IEC-60870-5-104.

Operation with a local PC via independent communication interfaces: RS232 and USB (via
uCZIPstd and uCZIPnet).

Self-check of operational correctness of important unit elements; all semiconductor
components are manufactured according to reliable static logic (also in case of memory) for
industrial applications.

Software upgrade – all software components (both firmware and the APPLICATION for a given
bay) can be reprogrammed via RS-232, RS-485 and USB.
