SIRIUS 3RS70 Signal Converter


Siemens Sirius 3RS70 signal converters perform the coupling function for analogue signals on both the input side and the output side. They are indispensable when processing analogue values with electronic controls. Under harsh industrial conditions in particular, it is often necessary to transmit analogue 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.

Electromagnetic disturbance and overvoltage’s can affect the signals on the input side in particular or even destroy the analogue modules. All terminals of the 3RS70 signal converters are safe up to a voltage of 30 V dc and protected against switching poles. Short circuit protection is an especially important function for the outputs.

Thanks to galvanic separation, the signal converters prevent mutual interference between the analogue channels. Thanks to the narrow and compact design, they take up little space on the mounting rail, particularly in flat control boxes and control cabinets with small gaps between tiers.

The high-quality, modern design in titanium grey contributes to the integrated appearance matching all other Siemens devices in the control cabinet. Active and passive single-range, multi-range and universal converters are available with various supply voltages and connection types for various analogue standard signals and other common sensor signals.
