1756-IF8I Isolated Analog Input Module
The 1756-IF8I module has eight isolated channels. Each channel supports
connection to the following input types:
• Current
• Vo l t ag e
The module provides 24-bit resolution and uses differential inputs. Differential
inputs have a greater resistance to the effects of electromagnetic noise and provide
improved flexibility regarding cable length when wiring your module.
