17.4.4 Valve Position Output and Feedback Input Wiring
CAUTION
1) Use an auxiliary relay for load-switching if the contact rating is exceeded.
2) Keep the relay output wires and the feedback input wires at least 30 cm apart.
3) The output relay has a limited service life. Be sure to connect a CR filter (for AC)
or diode (for DC) to the load.
4) If there is a risk of external lightning surges, use a lightning arrester etc.
5) This should always be used with a load of 10 mA or more.
