Industry Pack Modules Industry Pack Modules IP480 Counter/Timer IP480 modules provide up to six counter/timer channels for counting events, generating waveform control signals, measuring pulse-widths or periodic rates, and monitoring operations. Support for internal or external triggering simplifies the synchronization of operations to specific events. Counter The IP480 is very flexible and available in several varieties to accommodate a broad range of counter/timer applications. functions can use internally generated clocks or an externally supplied clock. IP Compliance (ANSI/VITA 4) Specifications Meets all written IP specs per ANSI/VITA 4-1995.
