The F-8017C2 is a 16-bit, 16-channel analog differential input module. This module accepts current input
range 4~20mA and supports 25% overrange measurement (Accuracy is not guaranteed). Besides, it has ±
0.05% accuracy for highly accurate application. Moreover, this module is built-in 2 ADC to provide same
sampling rate as F-8017C1 for some application. The F-8017C2 provides 3000VDC optical isolation
between channels and backplane bus. If any high voltage or current damages these channels, this module
won’t affect other component in iDCS-8000 system.
