Brand: Hunter Industries SKUs: ICD-100 / ICD-200 / ICD-400 Product Overview The Hunter ICD decoder family provides field control for compatible Hunter ACC2 decoder controllers and legacy ACC-99D two-wire systems. This Big Frog Supply product includes the one-station ICD-100, two-station ICD-200, and four-station ICD-400 variants. Each decoder receives commands and operating power through the shared two-wire path, then activates the assigned irrigation valve solenoid or solenoids near the field installation point. ICD decoders support two-way communication, integrated surge protection, field programming, and color-coded lead wires for installation. Station numbers can be assigned through a compatible controller before installation or programmed wirelessly in the field with a Hunter ICD-HP handheld programmer. Industrial-grade DBRY-6 waterproof connectors are included for the two-wire path splices, and a grounding lead is incorporated into each decoder for the required surge-protection layout. Hunter rates the decoder enclosure IP68 for submersible valve-box conditions. The maximum recommended distance from a decoder to its connected solenoid is 150 feet. With approved Hunter ID wire and a properly designed system, the maximum two-wire path can reach 10,000 feet with 14 AWG ID1 wire or 15,000 feet with 12 AWG ID2 wire. Actual system limits depend on the controller, wire layout, decoder count, grounding, voltage drop, and site conditions.

Use approved Hunter ID wire sized for the planned path length and system load. Follow Hunter spacing, grounding, surge-protection, waterproof-splice, and wiring requirements. Program and verify the decoder address before completing underground installation. Do not exceed the controller’s station capacity, simultaneous-output limit, or wire-path design limits. The ICD-600 six-station decoder and ICD-SEN sensor decoder are separate models and are not variants on this product. Frequently Asked Questions Can ICD decoders be used with a standard conventional controller? No. They require a compatible Hunter two-wire decoder controller such as an ACC2 decoder model or legacy ACC-99D. What is the difference between ICD-100, ICD-200, and ICD-400? The model number identifies how many station outputs the decoder controls: one, two, or four. Are waterproof connectors included? Hunter includes industrial-grade DBRY-6 connectors for the two-wire path splices. Additional connectors may be required for the full installation. Why Buy from Big Frog Supply? Big Frog Supply carries Hunter ACC2 controllers, ICD decoders, ID wire, waterproof connectors, valves, grounding components, and two-wire irrigation accessories.
