  • Page 3: 2-Wire Decoder System Overview

    2-Wire Decoder System Overview A Rain Bird ESP-LXD 2-Wire Decoder Control System provides modular control of small to large irrigation systems. Unlike traditionally-wired controllers that power the valve solenoids directly through individual valve wires, a 2-wire decoder controller uses a 2-wire cable to interconnect decoders that in turn control the valve solenoids.

    (usually a maximum of 48 stations) and required power drops. Designed for Protection from the Elements The field components of a Rain Bird ESP-LXD 2-Wire Decoder System are designed for underground burial, so they are all completely weatherproof. This makes a 2-wire decoder system a perfect application for a site that can be affected by flooding.

  • Page 5: 2-Wire Path Layout And Connections

    2-Wire Path Layout and Connections The design of a Rain Bird ESP-LXD 2-Wire Decoder Controller system requires careful consideration to the layout of the decoders on the 2-Wire path. Since a decoder system powers the electric solenoids through the 2-wire path, the 2-wire path must be able to provide enough voltage to power the solenoids.
