The Rain Bird LXIVMSD IVM‑SD is a surge protection module designed for 2‑Wire irrigation systems. It safeguards the ESP‑LXIVM controller and field devices from transient voltage spikes, reducing equipment damage and downtime while preserving system diagnostics.

  • Surge protection for 2‑Wire path: Provides targeted transient suppression for the 2‑Wire communication line.
  • Controller compatibility: Designed for use with ESP‑LXIVM series controllers and IVM field devices.
  • Installation spacing: Install one IVM‑SD at least every 500 feet (150 meters) of 2‑Wire cable or every 15 devices, whichever is smaller.
  • Grounding required: The 2‑Wire path and surge device must be properly grounded to ensure protection and meet warranty requirements.
  • Inline field mounting: Fits along the 2‑Wire path near field devices to limit surge exposure to the controller and decoders.
  • Reduces downtime: Helps prevent component failures caused by lightning and electrical transients, lowering repair time and costs.

Technical documentation and installation guidance are available in the LX‑IVM product manual (link provided on the product page). Use certified wiring connectors and follow local electrical codes when fitting the LXIVMSD to ensure reliable protection and safe operation.
