IM DL850E-03EN
Item Specifications
Math source waveforms Analog channels 1 to 16 and the sub channels of scanner and CAN modules.
• Math results can be specified as sources of another channel.
• However, you can only specify math results of channels whose numbers are smaller
than the channel that you are specifying sources for.
Math delay A uniform delay for each math operation, regardless of the number of math channels
Mean The mean can be calculated on the math results.
Number of taps: 32 (fixed)
The calculation period changes automatically according to the DL850E/DL850EV
sample rate.
