Attention: Analog input signals must be within +14.25V
referenced
to module common.
This input signal includes any
common
mode voltage present between either input
terminal
and module common. If an input terminal
exceeds this range,
channeltochannel crosstalk can cause invalid input
readings and invalid underrange or overrange bits.
The 1771IFE module does not supply loop power for the input
device. The user must supply loop power for looppowered
input devices.
