SIRIUS Coupling Relays and Signal Converters

Siemens SIRIUS coupling relays and signal converter devices control systems with a wide array of options

Image of Siemens SIRIUS Coupling Relays and Signal ConvertersSiemens coupling relays are globally applicable without any problems. Low-noise SIRIUS power relays with a long service life are available for switching high loads or high inrush currents.

Signal converters perform the coupling function for analog signals on both the input side and the output side. They are indispensable when processing analog values with electronic controls. Under harsh industrial conditions in particular, it is often necessary to transmit analog signals over long distances. Electrical separation is then needed as a result of the different power supplies. The resistance of the wiring causes potential differences and losses which must be prevented.
