The Hunter A2C-D75 decoder expansion module adds 75 stations to ACC2 Decoder controllers and is designed for large commercial and municipal irrigation systems. Built for compatibility with Hunter ICD decoders, the module delivers scalable performance, reliable two‑wire communications, and advanced flow diagnostics to simplify installation and maintenance on complex projects.

  • Expandable capacity: 75 stations per module; multiple modules allow expansion to 225 stations for very large sites.
  • Two‑wire flexibility: supports up to three two‑wire paths per output module for simplified valve wiring and reduced trenching.
  • Long run capability: compatible with long two‑wire runs (up to 10,000' with 14 AWG or up to 15,000' with 12 AWG), for expansive site layouts.
  • Advanced flow control: integrates with ACC2 Flow Manager to water efficiently—supports up to 30 simultaneous solenoids (maximum 20 per output module) at user‑specified flow rates.
  • Diagnostics and monitoring: Flow Monitoring provides fast detection of abnormal flow and stores histories for up to six flow zones for troubleshooting.
  • Professional features: 32 independent programs, 10 start times, stacking/overlap options, and a reversible full‑color LCD facepack for easy field service.
  • Durable and compatible: designed for commercial use and direct compatibility with Hunter ICD decoders and approved two‑wire components.

Use the A2C‑D75 when a project requires modular expansion, dependable two‑wire decoder communication, and on‑site flow diagnostics. The module streamlines wiring and lets contractors scale ACC2 systems quickly while maintaining accurate flow management and rapid fault detection.
