Brand: Hunter Industries SKUs: PCM-300 and PCM-900 Product Overview The Hunter PCM expansion-module family adds conventional wired stations to compatible modular Pro-C irrigation controllers. This listing includes two module choices: the PCM-300 adds three stations, while the PCM-900 adds nine stations. These modules allow an existing controller to grow as new irrigation zones are added without replacing the entire cabinet and facepack. Module compatibility and placement depend on the Pro-C controller generation, base station count, installed modules, and maximum supported conventional capacity. The selected module should match both the number of additional zones required and the controller's approved expansion configuration. Variant Options PCM-300: Adds 3 conventional stations PCM-900: Adds 9 conventional stations Key Features Genuine Hunter Pro-C expansion modules Adds conventional 24 VAC station outputs Supports controller expansion without replacing the complete Pro-C assembly Useful for new zones, system additions, or replacing a failed matching module Module-only listing; controller cabinet and field wiring are not included Common Uses Adding irrigation zones to a compatible Pro-C controller Replacing a damaged PCM-300 or PCM-900 module Expanding residential or light-commercial conventional wired systems Planning phased landscape and irrigation improvements Compatibility and Installation Notes Verify the controller's model label, date code, existing modules, available slot, and maximum station capacity before ordering. Older and current Pro-C generations can use different module arrangements. Disconnect controller power before installing or removing modules and follow the Hunter manual for the specific controller generation. Frequently Asked Questions Does this listing include a complete Pro-C controller? No. It includes the selected expansion module only. Which module should I choose? Choose PCM-300 when three additional conventional stations are required or PCM-900 when nine are required, after confirming the controller supports that module and capacity. Will these modules fit every Pro-C controller? Not necessarily. Confirm the controller generation and approved module arrangement before ordering. Why Buy Hunter PCM Modules from Big Frog Supply? The important difference between these variants is the number of stations added. Big Frog Supply separates the three- and nine-station choices and highlights the controller-generation check needed to prevent ordering a module that exceeds the installed Pro-C's supported configuration.
