Hi All -
This is my first post on this forum.
I have a surplus of SICK WT150-p162 proximity sensors / switches for use on automation / process control type industrial stuff. Hooked one up to an old laptop power supply at 20 volts and tested the output, getting 20 volts on detection and 0 volts normal. I want to use these sensors on a digital port of a picobotics servio board. Thing is up until now I have only had sensors etc that output 5v high, and I assume it is not healthy to put the digital port high with 20 volts, so the question is, can I use the SICK sensors, using the output voltage from the switch to turn the digital input on the servio high? If so how do I get that 20 volts down to 5 volt? I have thought about a voltage divider or a voltage regulator. Given that it is low current stuff would a 5v voltage regulator do the trick, and if I have 8 of them do I need to regulate each one or can I run all sensors from one regulator?
