SensorDAQ Physical Channels

SensorDAQ has analog input, analog output, digital I/O, and counter channels. It also has three analog sensor channels (labeled Ch. 1, Ch. 2, and Ch. 3 on the device) and one digital sensor channel (labeled DIG on the device) for use with Vernier sensors. Please contact Vernier for additional information on the analog and digital sensor channels.

Analog Input

SensorDAQ has two AI physical channels, Dev1/ai0 and Dev1/ai1. When you configure a channel in differential mode, Dev1/ai0 is the positive input and Dev1/ai1 is the negative input.

Analog Output

SensorDAQ has two AO physical channels, Dev1/ao0 and Dev1/ao1.

Digital Input/Output

SensorDAQ has four digital I/O physical channels.

Counter Input and Output

There is one counter channel referred to by the physical channel name Dev1/ctr0. pfi0 is the terminal used for this physical channel.
