Application

SICAM I/O Unit 7XV5673 is a digital input/output
device and is used by utilities (energy supply compa-
nies) in substation environment. The device is also
used for industrial sectors and in businesses with
increased environmental 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. The device is applied, for example:
For the bidirectional transmission of power protection
and control signals via serial connections (RS485/
Fiber Optical) or Ethernet
The acquisition and output of binary signals from the
connected substation control system or protection
devices using Modbus TCP/UDP, Modbus RTU, or
IEC 61850 (GOOSE, MMS, Reporting)
Contact multiplication of binary input signals
Inputs and outputs of the SICAM I/O Unit
The SICAM I/O Unit includes 2 terminal blocks, each
provided with 3 binary inputs and 3 relay outputs. It also
has an Ethernet port with an integrated Ethernet switch
and a serial interface in the form of an RS485 interface
or an optical interface (820 nm).
2 binary inputs are connected to common potential, one
binary input is not connected to common potential (iso-
lated). The threshold voltage of the binary inputs can be
set to DC 19 V, DC 88 V, or DC 176 V. This enables
optimum adjustment to the voltage of the substation
battery.
The digital outputs are relay outputs. 2 relay outputs are
designed as an NO (normally open) and one relay out-
