6000 Series Digital I/O Modules
Series 6000 digital I/O modules record signals from frequency counters, flow meters, encoders, discrete transducers, IRIG time, etc. which are often part of the test environment. These digital signals are time aligned and recorded alongside the system’s analog measurements. High density digital inputs provide an opportunity to easily include facility controls like switches, valve positions, relays, lights, etc. along with the test data. Series 6000 digital I/O modules also provide outputs generated by user command or automatically by Sequence, Alarms or DSP. User generated outputs are accomplished in software while sequencers can be programmed prior to a test and initiated by program or hardware control. Alarm conditions preprogrammed on the analog side can automatically generate digital outputs which are typically connected to facility control systems or PLCs. A DSP adds powerful real-time processing and is appropriate for PID control loops, derived parameter calculations and a variety of other real-time operations.
