What is the 5B Series and when is it a reliable option?

The 5B Series of analog signal conditioning modules perform single-channel analog signal conditioning for National Instruments E Series DAQ devices. These modules are installed into 8 or 16 channel carriers or backplanes that connect to the data acquisition device, providing assorted isolated signal conditioning on a channel-by-channel basis.

5B Series analog signal conditioning are legacy devices and are a reliable choice when you have a low-channel count application requiring isolation above 300 V. National Instruments recommends our SCC system for low-to-medium channel count applications that do not require this level of isolation, and we recommend our SCXI signal condition system for medium-to-high channel count applications with isolation requirements above 300 V.

You connect your I/O signals to connectors in the carrier or backplane of your 5B system, not the modules. After the 5B modules condition the signals, they are routed to your E Series DAQ device. Each module is connected to a dedicated input line of the DAQ device. NI offers a variety of carrier and backplane options for 5B Series modules.

5B Series Backplanes
For lower channel count applications, or applications where you want to use 5B analog output conditioning modules, consider choosing an 8 or 16-channel backplane.

• Directly cable E Series DAQ device to the backplane
• Analog output, digital I/O, and counter/timer signals available from a separate 26-pin connector that attaches directly to the 5B backplane

Shielded Carrier (SC-2311)
The SC-2311 is a shielded carrier that can hold up to eight 5B analog input conditioning modules and eight SSR digital signal conditioning modules.

• Custom connectivity options via panelettes
• 120/240 VAC power options

Power Supply
Power must be connected to the backplane, either from the optional power supply or an external source.

• An optional rack-mount bracket is available for the 5B Series backplane
