Has anyone wired a Gemu 1230 (with no LEDs)before? We have a design that is showing both opened and closed limits and is using a 2pr cable. The 24v and 0v are linked in the field and both signals are coming back. These are wired to separate channels on a Siemens 6DL1131-6BL00-0PH1) DI card. Gemu Drawing 101 on the datasheet.
Just to double check this will work as I have never come across it before ?
