The Hunter ACC2 Decoder 75 Station Expansion Module is a decoder output module used to add station capacity to compatible ACC2 Decoder controllers. It is designed for use with Hunter ACC2 Decoder systems where additional two-wire decoder station capacity is required.
Each A2C-D75 module adds up to 75 decoder stations and provides up to three two-wire path connections to the field. A compatible ACC2 Decoder controller can use additional A2C-D75 modules to expand from 75 stations to 150 or 225 stations.
The A2C-D75 is part of the ACC2 decoder platform and is used with Hunter ICD decoders installed in the field. It is not a conventional wired station expansion module and should not be confused with the A2M-600 module used for ACC2 conventional controllers.
The module includes colour coding, surge protection and replaceable 20A mini blade automotive fuses. Correct two-wire path installation, grounding and waterproof field connections are important for reliable decoder system performance.
