Page 2: Introduction
Introduction GrowControl VX series digital interface modules connect Agrowtek’s intelligent controllers to devices in your growing environment. VX8i and VX12i modules feature eight discrete DC FET ouputs for directly driving 15Vdc/24Vac irrigation valves and other Dc devices. VX12i models also features four analog inputs. Analog inputs allow the connec- tion of SXL optical liquid sensors and other third party analog sensors for integration. -
