The Hunter PCM-900 is a 9-station plug-in expansion module designed for the modular Pro-C (PC-400) irrigation controller. It provides a simple, plug-and-play method to increase station capacity for residential and light-commercial landscapes, and is recognized automatically by the Pro-C firmware.

  • Adds nine additional conventional stations to a modular Pro-C controller; use with a PCM-300 module to reach the full 4–16 station build-out.
  • Plug-in installation with Power Lock™ connector for secure, tool-free mounting and automatic controller recognition.
  • Compatible only with PC-400 modular Pro-C controllers; not compatible with fixed 6-station or 12-station PCC models.
  • Installs in the upper expansion slots; ideal for expanding medium to large irrigation systems without additional wiring.
  • Backed by Hunter documentation and technical support—consult the owner’s manual for installation order, wiring diagrams, and safety information.

The PCM-900 delivers fast, reliable expansion for contractors and homeowners who need more zones without replacing the existing controller. Order this module to scale a Pro-C system quickly while maintaining consistent irrigation control across multiple zones.
