GrowControl™ VX8i Intelligent 8-Valve Irrigation Controller
GrowControl™ VX8i irrigation valve controller: eight 24 V AC or DC outputs for WX diaphragm valves or BV motorized ball valves, power supply included. UL Listed.
Irrigation Valve Controller
GrowControl™ VX8i modules have eight high-current outputs for AC or DC irrigation valves.
A selectable AC or DC output mode runs standard WX electric diaphragm valves or BV motorized ball valves, independently or up to four at once. A high-current 24 V power supply for the valves is included, and the VX8i connects instantly to GrowControl™ GCX controllers through GrowNET™.
Diaphragm or Ball Valves
Select AC output for WX diaphragm valves or DC output for BV motorized ball valves.
Protected Outputs
Valve outputs are rated 1 A maximum combined, with flyback protection and surge suppression on each output.
Built for the Job
Flexible and reliable for many applications, built on more than a decade of proven Agrowtek technology.
- LED indicators on the front panel show the status of each valve output.
- Rugged metal enclosure for wall mounting.
- High-current FET outputs for valves and other DC loads.
- Conduit knock-outs and screw terminals for easy electrical installation.
