Description
NI PCI-6251 output module DAQ board
PCI-6251
The NI PCI-6251 excels in scenarios requiring simultaneous data collection and control. Its 16-bit analog-to-digital converter (ADC) supports sampling rates up to 1.25 MS/s per channel, ensuring accurate capture of fast-changing signals in applications like motor testing, sensor validation, and process monitoring. The module’s analog inputs feature a wide voltage range (±0.2V to ±42V), accommodating diverse sensors without additional signal conditioning, while its 2 analog outputs (2.8 MS/s update rate) enable precise control of actuators or dynamic signal generation. Digital I/O lines, capable of handling 24mA loads, are ideal for triggering relays, interfacing with PLCs, or driving PWM-controlled devices in automation setups.

PCI-6251
The NI PCI-6251 is engineered to balance speed, accuracy, and versatility. Its NI-PGIA 2 programmable gain amplifier ensures rapid settling times at high scan rates, maintaining 16-bit precision even when measuring all 16 analog channels simultaneously. Built-in analog and digital triggering capabilities allow engineers to synchronize data acquisition with external events, such as machine cycles or sensor thresholds, eliminating latency in critical applications.
PCI-6251
Durability is a key design focus. The module’s galvanic isolation protects against voltage spikes, while overvoltage protection (±25V when powered on) safeguards inputs from accidental damage. Its compact form factor and low power consumption (3.5W typical) make it suitable for space-constrained control cabinets, while the PCI interface ensures robust data transfer for real-time analysis.
