The Hunter PC-DM Decoder Module is a two-wire decoder output module for compatible Hunter Pro-C and HPC modular irrigation controllers. It enables Hunter EZ Decoder System operation, allowing valve stations to be controlled through a two-wire path instead of individual conventional station wires.
The PC-DM allows compatible Pro-C and HPC controllers to support up to 32 total stations in a hybrid conventional and decoder layout. If the system is used as two-wire only, up to 28 decoder stations are available because the first four stations remain assigned to the controller base module.
The PC-DM is used with compatible EZ-1 or EZ-LR single station decoders. Each decoder station requires its own decoder, so the PC-DM provides the two-wire output while the EZ-1 or EZ-LR decoders are installed at the valve locations.
The PC-DM can only be installed in the last two station output slots of a compatible controller. It will not fit or operate in other station output slots.
