BS-MX-110 is a teleprotection device designed for multiplexing up to eight I/O interfaces and an RS-232/RS485/422 interface over fibre optic connection.
The device supports various connection topologies, including point-to-point, bus or ring.

Transparent data stream transmission combining signals from I/O and RS232/422/485 ports provides a flexible spectrum of potential uses, with a particular focus on minimising device lag and transmission not interfering with data transfer structure.


The eight digital inputs of the device are divided into two groups with the one (4 inputs) set to a fixed trigger level and the other (another 4 inputs) with configurable trigger voltage levels. Configuration of the four parametric inputs allows trigger level thresholds of 12V, 24V, 48V, 110V, 125V, 220V, and 250V.


The inputs provide the additional functionality of filtering interference, which is particularly important in power network management applications and insulation between inputs of over 50 MΩ/500V.


Analogue BS-MX-110 outputs are fitted with double contacts, NC on one side and NO on the other. Outputs are triggered by inputs of devices operating on the bus or ring with suitably configured addressing.
