- Bundle includes measurement module and 1-slot NI CompactDAQ chassis
- USB, Ethernet, and 802.11 Wi-Fi connectivity
- 8-channel, 1 µs high-speed digital output
- 5 to 30 V, sourcing digital output
- Hot-swappable operation
The NI 9474 Measurement System includes eight sourcing digital output channels capable of communicating with a host PC over USB, Ethernet or 802.11 Wi-Fi.
Measurement Bundle Overview
The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 Wi-Fi chassis and one of the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed measurements.
Chassis
The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 Wi-Fi bus. Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.
Module
The NI 9474 is a C Series 8-channel, 1 µs high-speed sourcing digital output module. It works in any NI CompactDAQ or CompactRIO chassis. Each channel is compatible with 5 to 30 V signals and features transient overvoltage protection of 2,300 Vrms between the output channels and earth ground. Each channel also has an LED that indicates the state of that channel. With the NI 9474, you can connect directly to a variety of industrial devices such as motors, actuators, and relays.
The NI 9474 module is a correlated digital module, so it can perform correlated operations, triggering, and synchronization when installed in an NI CompactDAQ chassis.
