9. The 1769 IF8 uses a digital filter that provides noise rejection for the input signals The filter is programmable allowing you to select from four filter frequencies for each channel The digital filter provides 3 db 60 amplitude attenuation at the selected filter frequency A lower frequency 60 Hz versus 250 Hz can provide better noise rejection but it increases channel update time Transducer power supply noise transducer circuit noise or process variable irregularities may also be sources of normal mode noise Common Mode Rejection is better than 60 dB at 50 and 60 Hz with the 50 and 60 Hz filters selected respectively The module performs well in the presence of common mode noise as long as the signals applied to the user plus and minus input terminals do not exceed the common mode voltage rating 10 V of the module Improper earth ground may be a source of common mode noise Channel Step Response The selected channel filter frequency determines the channel s step response The step response is the time required for the analog input signal to reach 100 of its expected final value This means that if an input signal changes faster than the channel step response a portion of that signal will be attenuated by the channel filter Publication 1769 UM002B EN P July 2005 3 24 Module Data Status and Channel Configuration for the Input Modules Publication 1769 UM002B EN P July 2005 Channel Cut Off Frequency The 3

97. dB frequency is the filter cut off frequency The cut off frequency is defined as the point on the frequency response curve where frequency components of the input signal are passed with 3 dB of attenuation All input frequency components at or below the cut off frequency are passed by the digital filter with less than 3 dB of attenuation All frequency components above the cut off frequency are increasingly attenuated The cut off frequency for each channel is defined by its filter frequency selection and is equal to the filter frequency setting Choose a filter frequency so that your fastest changing signal is below that of the filter s cut off frequency The cut off frequency should not be confused with the update time The cut off frequency relates to how the digital filter attenuates frequency components of the input signal The update time defines the rate at which an input channel is scanned and its channel data word is updated Module Update Time and Scanning Process The module update time is defined as the time required for the module to sample and convert the input signals of all enabled input channels and provide the resulting data values to the processor Module update time can be calculated by adding the sum of all enabled channel times Channel times include channel scan time channel switching time and reconfiguration time The module sequentially samples the channels in a continuous loop The 1769 IF8 uses two parallel sampling l
