Description
Four 32-Bit General-Purpose Counters Built In
The cDAQ-9174/78/79 chassis both have four 32-bit counters built in. These counters are accessed through an installed hardware-timed digital I/O module (sold separately) such as the NI 9401 or NI 9402. Once you have installed the digital module, you can create a counter task in software for operations such as quadrature encoder, period and frequency measurement, or finite pulse train and PWM generation. For some operations, you can access the counters in the cDAQ-9178/79 chassis through the built-in BNC connectors on the chassis.
Flexible Power Options
The upgraded chassis features a new physical connection for power supplies. Each chassis is shipped with an AC/DC converter that plugs directly into the chassis. (Note that the power cord to go from the AC/DC converter to the wall is sold separately.) For other power options, such as a power supply with leads for V/C, an automotive electrical system, or an off-the-shelf battery pack, purchase the screw-terminal accessory for the chassis to enable easy connection of a V and C lead to the chassis. NI CompactDAQ requires a 9 to 30 VDC power supply and uses a maximum load 25 W of power.
