1746-NI4 Analog Input Module

The 1746-NI4 Analog Input module contains 4 analog input channels
that are user selectable per channel for voltage or current to support a
variety of monitoring and controlling applications

1746-NIO4I and NIO4V Analog Combination Modules

The NIO4I and NIO4V Analog Combination I/O modules provide two
input and two output channels in a single slot module. The
1746-NIO4I module contains two current or voltage inputs (user
selectable per channel), and two current outputs. The 176-NIO4V
module contains two current or voltage inputs (user selectable per
channel) and two voltage outputs.

1746-NO4I and NO4V Analog Output Modules

The NO4I and NO4V Analog Output Modules provide 4 analog output
channels. The NO4I module contains four current outputs. The NO4V
module contains four voltage outputs. Both of these modules support
a variety of monitoring and controlling applications.
