SIRIUS 3RS70 signal converters

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.

Electromagnetic disturbance and overvoltages can affect the signals on the input side in particular or even destroy the analog modules. All terminals of the 3RS70 signal converters are safe up to a voltage of 30 V DC and protected against reverse polarity. Short-circuit protection is an important function for the outputs above all.

The devices are EMC-tested according to

• IEC 61000-6-4 (generic standard for emitted interference)
• IEC 61000-6-2 (generic standard for interference immunity)

The analog signals comply with

• IEC 60381-1/2.
