Signal connections

Analog input

You can connect up to eight analog input connections to CH0 IN through CH7 IN. Connect unused analog input

terminals to ground terminals during operation. For example, if you are not using terminal 15 (

CH7 IN), connect

this terminal to terminal 16 (

AGND).

The analog input channels are configured for single-ended input mode. Each analog signal is referenced to

signal ground (AGND), and requires two wires:

 Connect the wire carrying the signal to be measured to

CH# IN.

 Connect the second wire to

AGND.

The input voltage ranges are ±10 V, ±5 V, ±2.0 V, ±1.0 V.

For more information on analog signal connections

For more information on single-ended inputs, refer to the Guide to Signal Connections (this document is

available on our web site at www.mccdaq.com/signals/signals.pdf).
