Module Common

1771WG

Field Wiring Arm

10948I

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.
