Hunter - Single Station Decoder With Surge Suppression and Ground Wire

SKU: ICD-100
  • The ICD-100 is a single station decoder for the ACC controller
  • Includes surge suppression and ground wire
  • Maximum recommended distance, decoder to solenoid: 150 ft.

The versatility of the ACC controller grows even more powerful with the addition of the two-wire decoder system from Hunter. ACC-99D uses two-wire decoders to control up to 99 stations without giving up the arsenal of features provided by the ACC. Operating large numbers of valves over long distances, the ACC99D decoder controller takes full advantage of the powerful ACC feature set. Since it’s two-wire powered, it also saves copper wire, simplifies troubleshooting, permits rapid addition of new stations, minimizes trenching, and permits remote sensor monitoring over the two-wire path.

The ACC-99D, Hunter’s most powerful controller, teamed with the most versatile decoders in the industry is an unbeatable combination for large sites with changing needs.

Each ACC-99D permits operation of 99 stations over one or more two-wire “paths” to the field. The full line of decoders comes in 1-, 2-, 4-, and 6-station waterproof configuration. You can even add in-line sensor decoders to monitor remote sensors, via the two-wire paths. Up to 6 different paths out of the controller may be used to make the most efficient use of wire, to minimize trenching and disruption of landscaping. Hunter’s color-coded, twisted pair IDWIRE is a cost-effective, easily-installed, direct burial wiring solution that resists surges and electrical noise, while providing high tensile strength for permanent in-ground installation. The wire may also be spliced to follow piping in complex installations. Earth Grounding: The Hunter Difference. Every ICD decoder has lightning surge suppression, built in. Connect every 12th decoder to earth ground hardware (minimum) and there are no additional surge suppression devices required.
