Signal connections

Analog input

You can connect up to eight analog input connections to the screw terminal containing pins 1 to 20 (
through .) Connect unused analog input terminals to ground terminals during operation. For example, if
CH7 IN
you are not using terminal 15 (
All analog input channels are configured for single-ended input mode. All analog input signals are referenced to
ground ( AGND ):

Connect the wire carrying the signal to be measured to

Connect the second wire to
The input voltage ranges are ±10 V, ±5 V, ±2.0 V, ±1.0 V.

Channel-Gain queue

The channel-gain queue feature allows you to configure a different gain setting for each channel. The gain
settings are stored in a channel-gain queue list that is written to local memory on the device.
The channel-gain queue list can contain up to eight unique elements. The channel list must be in increasing
order. An example of a five element list is shown in the table below.
