Acromag, Inc. Counter/Timer Module, PMC Series PMC483

Four 16-bit counters - TTL, and four 32-bit counters - RS422 Event counter Frequency measurement Quadrature position measurement Pulse-width or periodic rate monitor Several models with a variety of configurations provide up to ten 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 functions can use internally generated clocks or an externally supplied clock.
