C Series Modular I/O

C Series modules combine A/D converters, signal conditioning, and signal connectivity in one package for measuring or generating one or more specific types of signal. C Series I/O modules are hot-swappable and automatically detected by the CompactDAQ chassis. I/O channels are accessible using the NI-DAQmx driver software.

Because the modules contain built-in signal conditioning for extended voltage ranges or industrial signal types, you typically make your wiring connections directly from the C Series I/O modules to your sensors/actuators. In most cases, the C Series I/O modules provide isolation from channel-to-earth ground. Check each module's specifications for more details.

Mounting CompactDAQ Hardware

You can mount a CompactDAQ chassis using a desktop mounting kit, 35 mm DIN-rail mounting kit, or panel mount accessory kit.

NI 9901 Desktop Mounting Kit

The NI 9901 desktop mounting kit includes two metal feet you can install on the sides of the CompactDAQ chassis for desktop use. With this kit, you can tilt the CompactDAQ chassis for convenient access to the I/O module connectors. When you install the two metal feet, the two existing screws on the back side and I/O end of the chassis must be removed, as shown in Figure 9. After removing the screws, replace them with the two longer screws included in the NI 9901 desktop mounting kit. You can use the NI 9901 desktop mounting kit with the following CompactDAQ chassis:

  • cDAQ-9174, cDAQ-9178
  • cDAQ-9184, cDAQ-9188, cDAQ-9188XT

Figure 9. NI 9901 Desktop Mounting Kit

DIN-Rail Mounting Kits

Each DIN-rail kit contains one clip for mounting the chassis on a standard 35 mm DIN rail. To mount the chassis on a DIN rail, fasten the DIN-rail clip to the chassis using a No. 2 Phillips screwdriver and two M4 X 17 screws. The screws are included in the DIN-rail kit. Make sure the DIN-rail kit is installed as illustrated in Figure 10, with the larger lip of the DIN rail positioned up. When the DIN-rail kit is properly installed, the CompactDAQ chassis is centered on the DIN rail. Use the following kits for each chassis:

  • NI 9915 for cDAQ-9178 and cDAQ-9188/9188XT
  • NI 9912 for cDAQ-9174 and cDAQ-9184
  • NI 9913 for cDAQ-9181 and cDAQ-9191

Figure 11. DIN-Rail Installation on cDAQ-9181 or cDAQ-9191

Panel Mount Kits

To mount the chassis on a panel, align the chassis on the panel mount accessory. Attach the chassis to the panel mount kit using two M4 X 17 screws. NI provides these screws with the panel mount kit. You must use these screws because they are the correct depth and thread for the panel. These slots in the panel mount kit can be used with M4, M5, No. 8, or No.10 panhead screws. Figure 12 illustrates the panel dimensions and installation on the CompactDAQ chassis. Refer to the documentation included with the panel mount kit for more detailed dimensions. Use the following kits for each chassis:

  • NI 9905 for cDAQ-9178 or cDAQ-9188/9188XT
  • NI 9904 for cDAQ-9174 and cDAQ-9184
  • NI 9903 for cDAQ-9181and cDAQ-9191
