Rain Bird ESPSM3 Expansion Module

The Rain Bird ESPSM3 is a 3-station expansion module designed for the ESP-ME3 modular controller. If your garden grows or you need extra watering zones, simply slide the module into a free expansion slot and wire the new valves: three additional stations are ready to program. The ESP-ME3 provides three expansion slots and reaches up to 22 stations in total, combining its 4 base stations with ESPSM3 (3 stations) and ESPSM6 (6 stations) modules. Modules can be added without powering the controller down, so the upgrade is quick and clean. Each additional station is programmed from the controller's 4 independent programs, with 6 start times per program. The ESPSM3 is supplied as a single module; the controller, valves and wiring are sold separately. A practical way to extend an existing ESP-ME3 installation instead of replacing the controller.
