About 1794-IE8
Using the module’s Eight (8) single-ended, non-isolated, user configurable channels capable of receiving 0 to 20mA, 4 to 20 mA, +/- 10VDC and 0 to 10 VDC input signals, this module is capable of interfacing instruments such as field transmitters, analog indicating instruments, recorders, process loop controllers and other analog instruments that generates the compatible signal ranges.
This Flex I/O analog input module has a resolution of 12 bits when configured in unipolar mode and 11 bits plus sign for bipolar mode. It uses a successive approximation conversion and save the converted data in data format of eft justified, 16-bit 2s complement. It has a conversion rate 256?s on all channels with absolute accuracy of 0.20% Full Scale @ 25°C and accuracy drift of – 0.00428% Full Scale/°C for Voltage and 0.00407% Full Scale/°C for current input. This module does not require calibration.
