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 faults 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 30 V DC and protected against switching poles.
Short-circuit protection is an especially important function for the
outputs.
The devices are EMC-tested according to
- EN 50081 (basic specification for emitted interference)
- EN 61000-6-2 (basic specification for interference immunity)
The analog signals comply with - IEC 60381-1/2
