It might be that one of Siemens new ‘transducers’ is the solution you didn’t know you were looking for. Here are some highlights, but please feel free to contact us, as several of these have more options and capability for even more versatility!
7XV5674: 12 x mA inputs to MODBUS RTU or IEC 61850 GOOSE
Note that the Ethernet interface has a built-in Ethernet switch, allowing further 7XV5674’s or other devices to be cascaded via a ‘Y’ cable.

7XV5653: 2 input/2 output binary transducer
The 7XV5653 allows users to transfer binary information between the two modules, up to 3 km apart, via a multi-mode fibre optic cable. With other Siemens media converters installed, distances of up to 170 km can be traversed via single mode fibre. Pilot wire or switched digital networks are also supported with other media converters.
Transmission link monitoring and power supplies monitoring is integrated.

7XV5673: 6 input/6 output binary transducer (with IEC 61850 GOOSE)
A similar concept to the 2 binary input/output device above, but with:
- 6 binary inputs, 6 binary outputs
- Copper RS-485 or optical communication between units (MODBUS RTU)
- Copper Ethernet, supporting MODBUS TCP or IEC 61850 GOOSE
The 7XV5673 also has a built-in Ethernet switch allowing units to be daisy chained, without need for an additional Ethernet switch.
The 7XV5673 works nicely with Siemens SIPROTEC Compact feeder protection relay 7SJ80 to provide distributed relay I/O, for example, allowing you to mount the I/O out at an outdoor substation junction box, etc.
