9.6.7Connecting 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 Respect to Ground 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:	M0 +
	M0 ±
Channel 1:	M1 +
	M1 ±
:	:
Channel 15	M15 +
	M15 ±

Channels are arranged in groups of four, for which you can set separate measuring ranges:

Channel group I: Channel group II: Channel group III: Channel group IV:

Channels 0 to 3 Channels 4 to 7 Channels 8 to 11 Channels 12 to 15
