User Information
Application Scope
SICAM I/O Unit 7XV5673 is a digital input/output device and is used by utilities (energy supply companies) in
substation environment. The device is also used for industrial sectors and in businesses with increased envi-
ronmental requirements. It can be used in nearly every application for protection relays or SCADA, e.g. over
current protection, teleprotection or Substation Automation. Nearby and remote connection of binary I/O Inputs
are possible using this SICAM I/O Unit.
In the manual, the short name
SICAM I/O Unit
is used.
The SICAM I/O Unit can be used as, for example:
•
I/O mirror: point-to-point transfer of binary signals between 2 SICAM I/O Units via Ethernet or a serial con-
nection
•
I/O expansion: device expansion by binary inputs and outputs
•
Contact multiplier: multiplication of signals on one or several binary inputs via relay contacts
Binary Inputs and Relay Outputs
The device contains 2 terminal blocks with 3 binary inputs and 3 relay outputs each, and an Ethernet
connection with internal Ethernet switch and a serial interface. Depending on the device variant, the serial
interface is designed as RS485 or FO interface (820 nm).
2 binary inputs have a common root on each terminal block. Another binary input is potential free (not
connected to potential). The threshold voltage of the binary inputs can be set to DC 19 V, DC 88 V or
DC 176 V. Therefore an optimal adjustment to the station battery’s voltage of the substation can be achieved
and the pickup voltage can be adjusted in the case of increased interference level.
Each terminal block has 2 relay outputs NO (normally open) and one relay output CO (change over). The
relays can switch voltages up to AC/DC 250 V and currents up to AC/DC 5 A.
Function
Via binary inputs, all kinds of binary signals of switch gear/protection scheme (for example tripping command,
switch position signal, fault and status indications) are securely detected. This information can directly be dis-
tributed at this SICAM I/O Unit over relays, or be transmitted over communication ways to further equipment or
systems.
The information is transmitted protected about the Ethernet and the serial interface in telegrams.
The parameter setting is simply carried out with a standard Web browser at the PC which is connected by the
Ethernet interface. A separate software is not required.
