Sink logic (negative common)/source logic (positive common)
Current flowing out turns control input terminals on. These are called sink logic terminals (The end of Type
- form : AN / WN). The general used method in Europe is source logic in which current flowing into the in-
put terminal turns it on(The end of Type - form : WP).
