Product Overview
The Toro RXC4-MOD is a 4-station expansion module designed for compatible Toro RXC Series irrigation controllers. This plug-in module adds four additional conventional irrigation zones, allowing an RXC controller to grow with the landscape without replacing the base controller. The RXC Series starts with a 6-station base controller and expands in 4-station modules up to 22 total stations, making the RXC4-MOD a practical add-on for residential and light commercial irrigation systems that need more zone capacity.
