Section 1.2
Increased Accuracy
and Reliability
The counter module offers
±
1 count accuracy and
±
1% or better frequency
measurement accuracy. Programmable functions allow the user to define counter
ranges and flags to accommodate process-specific requirements. Full speed
counter operation of over 50kHz is possible .
Section 1.3
Reduced System
Costs
High Channel density allows for lower resource usage. Eight channels consume
the resources associated with a standard two channel module.
Section 1.4 State-
of-the-Art
Performance
These modules incorporate state of the art Programmable Gate Array technology
that allows high circuit density and functionality. The module uses proprietary
Allen-Bradley technology, so they operate and perform like the latest Allen-
Bradley products. They also provide high resolution, user-programmable range
settings, continuous temperature compensation (no field calibration), software
configuration, programmable output limits, and programmable safe states in case
of a fault.
