Connecting Sensors to the 466 Analog Input Module

The connections for the 466 analog input module depend on the type of
measurement (with respect to ground or differential measurement).
Measurement with
For measurement with respect to ground, all signal lines have a common

reference point. This is achieved by connecting all the M inputs in use to one
point. Since this type of measurement is susceptible to interference, the
signal sources should be arranged in the vicinity of the 466 analog input
module.
16 channels are available; unused channels must be shorted (jumper between
M+ and M-).
The channels have the following designations on the module:
Channel 0:
Channel 1:
:
Channel 15
Channels are arranged in groups of four, for which you can set separate
measuring ranges:
Channel group I:
Channel group II: Channels 4 to 7
Channel group III: Channels 8 to 11
Channel group IV: Channels 12 to 15
