The inputs are fully programmable and can accepts signals representing speed, phase reference, vibration (acceleration, velocity or displacement), dynamic pressure, airgap rotor and pole profile, any dynamic signals or any quasi-static signals. Signals can be input from adjacent Machinery Protection Cards (MPC4) via the 'Raw Bus' and 'TachoBus’or externally via the screw terminal connectors on the IOC16T. The lOC16T modules also afford signal conditioning and EMC protection and allow inputs to be routed to the CMC16, which includes 16 programmable tracked anti-aliasing filters, and Analog-to-Digital Converters(ADC). On-board processors handle all control of acquisition, conversion from time domain to frequency domain(Fast Fourier Transform), band extraction, unit conversion, limit checking, and communication with the host system.

The 10 available outputs per channel can include RMS, peak, peak-peak, true peak, true peak-peak values, Gap, Smax, or any configurable band based upon synchronous or asynchronously acquired spectra. Acceleration(g), velocity(in/sec, mm/sec)and displacement (mil, micron) signals are catered for and can be converted for display to any standard. lf configured, data is sent to the host computer only on exception, for example, only if the change of value exceeds a pre-defined threshold. Values can also be averaged for smoothing or noise reduction.

Events are generated when values exceed one of the 6 configurable limits, exceed rate-of-change alarms or deviate from stored baselines. However, adaptive monitoring techniques can also be employed to dynamically adjust alarm set points based upon machine parameters such as speed and load.

The CMC 16 acquires and processes high-resolution data captured at scheduled intervals or on alarm detection (waveforms, spectra and orbits). Spectral resolution, frequency span or order span, window type, averaging mode and number of averages are fully configurable. The capacity also exists to trigger extended capture of time-based data over several minutes using an ‘Oscilloscope Mode’ as this can provide valuable data, particularly during machine start-up.
