Product Details
The module senses voltage transitions from magnetic transducer input devices, accumulating them during a selected window of time (rate measurement). The resulting count is used to generate a frequency or RPM which is transmitted to the Main Processors. The pulse count is measured to 1 micro-second resolution.
The PI module includes three isolated input channels. Each input channel independently processes all data input to the module and passes the data to the Main Processors, which vote on the data to ensure the highest integrity.
Each module provides complete ongoing diagnostics on each channel.Failure of any diagnostic on any channel activates the Fault indicator, which in turn activates the chassis alarm signal. The Fault indicator merely indicates a channel fault, not a module failure. The module is guaranteed to operate properly in the presence of a single fault and may continue to operate properly with certain kinds of multiple faults. The Pulse Input Module supports hot- spare modules.
WARNING: The PI module does not provide a totalization capability-it is optimized for measuring the speed of rotation equipment.
