User manual - GALVANIC SEPARATOR SGS-61
–
Avoid common (parallel) leading of signal cables and transmission cables together with
power supply cables and cables controlling induction loads (e.g. contactors). Such cables
should cross at a right angle.
–
Contactor coils and induction loads should be equipped with anti-interference protection
systems, e.g. RC-type.
–
In the case of magnetically induced interference the use of twisted couples of signal
cables (so-called “spirals”) is recommended. The spiral (best if shielded) must be used
with RS-485 serial transmission connections.

polarization of signal is essential. Output - passive current loop should be powered by nominal
voltage (any polarization) and connected to the output load (Figure 4.4.).
