■Sink logic (negative common)/source logic (positive common)

⋅⋅⋅Logic switching of input output terminals

Current flowing out turns control input terminals on. These are called sink logic terminals. (For all models except models with a built-in noise filter, control input terminals are factory-set to sink logic.) The general used method in Europe is source logic in which current flowing into the input terminal turns it on.
