The Siemens SICAM 7XV5673 is an I/O unit that can be used for:
- Binary I/O expansion
- Transferring binary signals – binary I/O mirror
- Contact multiplication
The SICAM I/O unit is ideal for substation automation applications. The one unit features a 24-220 Vdc operating range, allowing it to be used on 24, 48, 110 and 220 V systems! This I/O unit features 6 binary inputs (with selectable 19, 88 or 176 Vdc threshold) and 6 binary outputs (rated 250 V 5 A ac/dc).
GOOSE messaging is now supported for Binary I/O expansion applications (in addition to MODBUS TCP). This allows GOOSE messages from an IED to be output to a 7XV5673 to operate relay contacts, or binary inputs to the 7XV5673 to be sent as GOOSE messages to the IED and/or other devices. Thus the 7XV5673 can be used as remote (or local) I/O expansion for IED’s with an IEC 61850 interface.
For I/O binary mirror applications two (or more) 7XV5673 units can be connected together via electrical RS-485, fibre optic RS-485 or Ethernet to allow transfer of I/O across small or large distances. The different communication media makes this a truly versatile product, where “mirroring” can occur from one-to-many if desired – without need for additional comms servers etc.
Another application for the I/O unit is as a contact multiplier, where one input can be transmitted to different locations using multiple I/O units, or one input can be output to two or more output contacts. This latter capability is a useful solution for applications where different voltage levels need to be switched or isolation maintained between systems, such as transmitting a binary status to both 24 V and 110 V I/O equipment.
The options and applications for the 7XV5673 unit are virtually unlimited!

In last month’s newsletter we mentioned 7SJ80 Feeder Protection Relay with DNP and IEC 61850 support. This relay is a perfect example where the 7XV5673 could be used as a local or remote GOOSE connected I/O expansion to the Feeder Protection Relay – while preserving DNP-iP protocol to SCADA.
