The Smart Logger has digital output (DO) pins that can be used for turn ON/OFF external devices.
The DO port supports a maximum of 12 V signal voltage. The NC/COM is a normally closed contact, while the NO/COM is a normally open contact. It is recommended that the signal transmission distance be less than or equal to 10 m.
