Rain Bird ESP12LXMEF 12-Station Modular Controller

The Rain Bird ESP12LXMEF is a commercial-grade, modular irrigation controller engineered for reliability and advanced water management. Factory-equipped with the Flow Smart Module, the ESP12LXMEF delivers precise flow sensing and hydraulic demand management for medium-sized landscapes, and expands easily with hot‑swappable station modules.

• Factory Flow Smart Module: Built-in Flow Smart functions (Learn Flow, usage totalizer) for real-time flow monitoring and protection.
• Expandable Modular Design: Start at 12 stations and expand up to 48 stations using 8- and 12-station modules without powering down.
• Advanced Water Management: FloWatch high/low flow protection, FloManager hydraulic demand management, Cycle+Soak and SimulStations for overlapping operation.
• Robust Programming: Four independent programs (A–D), station timing 0 min–12 hrs, seasonal adjust 0–300% and programmable station delays.
• Commercial Reliability: 10kV surge protection, non-volatile (100-year) memory and removable front panel programmable on battery power.
• Integration & Compatibility: Works with IQ4 central control, weather sensor input, master valve/pump start and is compatible with standard flow sensors.
• Power & Dimensions: Model ESP12LXMEF operates on 120 VAC; enclosure measures approximately 14.32" W x 12.69" H x 5.50" D.

This controller includes downloadable technical documents—installation, programming charts and wiring diagrams—to simplify specification and installation. Choose the ESP12LXMEF when you need a durable, serviceable controller with built-in flow management and easy future expansion.
