Types of Analog Modules
1746-NI4 Analog Input Module
The 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-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.
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 1746-NIO4V module contains two current or voltage inputs (user
selectable per channel) and two voltage outputs.
1746-FIO4I and FIO4V Fast Analog Combination Modules
The FIO4I and FIO4V Fast Analog Combination modules are 2-input/2-output
combination modules ideal for high speed applications with more rapidly
changing analog signals. These fast response modules are best suited for control
of pressure and position in equipment such as hydraulic presses and molding
machines.
Analog Modules Operation
The module converts analog input signals to 16-bit binary values for storage in
the SLC processor’s input image table. The decimal range, number of significant
bits, and converter resolution depend on the input range that you use for the
channel.
