Advantech’s APAX-5080 Counter Module features up to eight channels and hot-swappable functionality. With its 4/8 counter channels, the APAX-5080 is capable of simultaneously taking counts from multiple sources using any of its five operating modes ( UP, UP/Down, Frequency, Pulse/Direction, and A/B Phase modes), therefore saving hardware installation costs and having greater scalability. The flexibility of the APAX-5080 is enhanced with the additional benefit of four DI counter gates to define when a counter is enabled, and four DO alarm output channels triggered by a specific counter value; so that the APAX-5080 can be configured to send an alarm message when certain criteria are met.
