Rapidly or continuously changing inputs may cause mis-compare readings because the measured values of the three channels may different by more than 0.5 percent of full scale, which can cause a fault to be declared in error. If the input readings differ by a minimum of 2 percent of full scale and continue for a minimum period of 40 input samples, the probability of a fault increases. 2% of full scale 1 scan or 200 ms, whichever is greater 40 samples 52 Chapter 2 System Components Planning and Installation Guide for Tricon v9–v10 Systems 3721 Specifications This section includes specifications for model 3721, which is a TMR Analog Input Module with a voltage range of 0 to 5 VDC or -5 to +5 VDC.
