Phase-out/discontinuation of SIRIUS 3RS17 interface converters

The phase-out period for SIRIUS 3RS17 interface converters began in September 2015. The devices will no longer available for ordering as from October 1, 2018. We therefore recommend that you do not delay in ordering the successor generation of signal converters, SIRIUS 3RS70!

The old devices can be replaced with devices from the new generation without restrictions. Our conversion tool is available for old and new as well as competitor conversions, seeВ http://www.siemens.com/sirius/conversion-tool.

If any further questions arise during your conversion activities, please do not hesitate to contact our Technical Assistance, either via telephone on +49 (911) 895 5900 or via email at technical-assistance@siemens.com.

More information on the new SIRIUS 3RS70 signal converters can be found under Monitoring and Control Devices > Relays > Coupling Relays and Signal Converters/Interface Converters > SIRIUS 3RS70 Signal Converters or at http://www.siemens.com/relays.

Interface 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. This means that electrical isolation is essential due to the different supply systems. 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 3RS17 interface converters are safe up to a voltage of DC 30 V and protected against switching poles. Short-circuit protection is an especially important function for the outputs.

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

• IECВ 60381-1/2.
