Selected Add-Ons


Expand your GrowControlTM System with a GC-XO Slave Controller

The GrowControlTM GC-XO slave adds more outputs to existing GC-Pro or GC-ProXL series controllers. GC-XO controllers have the same construction as GC-Pro controllers, but are equipped with only outputs for turning relays on an off. Slave controllers do not have any of their own control functions, they simply turn on and off as required by the "master" controller that they are listening to.

Simply connect the GC-XO Slave controller into the same Ethernet network as the master to expand your system! The GC-XO is told what to do by the 'master' controller over the Ethernet connection. A slave can be located a distance from a master thanks to the network link between the two.

RX / CX / RD Relays

The controller's low-voltage 24Vdc outputs are wired to Agrowtek's RX, CX and RD series relays to control equipement power. Mix and match relay models to suite your environment and equipment control requirements. The GC-Pro can also be direct wired to existing or custom electrical relays panels.
