High-Precision DAQ Selection Guide Overview delivers ±42 V overvoltage protection and per-channel lowpass, antialiasing filters. An NI 4351 device features software-selectable ground referencing on a channel-by-channel basis, so you can measure both floating and groundreferenced signals together; it also features per-channel open-thermocouple detection. When open-thermocouple detection is enabled, the input channel is connected to +2.5 VDC through a 10 MΩ resistor. When a thermocouple breaks The NI PCI-4351 and PXI-4351 are precision computer-based digitizers designed or is disconnected, the reading rapidly increases to 100 mV or more, indicating specifically for high-accuracy temperature measurements (thermocouples, an open-circuit condition. RTDs, thermistors), resistance measurements, chromatography measurements, and low-frequency analog signal measurements within ±15 V. Available for PCI and PXI/CompactPCI, these devices feature ±0.42 °C, J-type thermocouple accuracy; ±0.12 °C RTD accuracy; ±0.03 °C thermistor accuracy; 5½-digit voltage measurements; power line noise rejection filters; and precision current source for RTD and thermistor excitation. NI 4351 devices combine the functionality Precision Current Excitation These devices feature a 25 μA precision current source for excitation of RTDs, thermistors, or other resistive devices. The source excites the total system resistance of up to 600 kΩ. An NI 4351 also features an additional 1 mA precision current source for RTDs or other resistive devices for total system of stand-alone temperature and voltage meters and chromatographs with resistance of up to 15 kΩ. the flexibility and benefits of your computer, so you can build highly capable Digital I/O and Alarm Outputs computer-based data-logging systems. As with all computer-based digitizers, NI 4351 devices can easily integrate into your Internet-based applications. Hardware Precision Analog Input NI 4351 devices have 16 differential analog inputs. Each device has a 24-bit analog-to-digital converter (ADC) and six possible reading rates – 10, 50, and 60 readings/s in single-channel acquisition mode and 2.8, 8.8, and 9.7 total readings/s in multiple-channel acquisition mode. For channel speed, divide the total readings/s by the number of channels acquired. Digital filters automatically An NI 4351 has eight 5 V/TTL digital lines. You can individually configure each line as an input or an output. You can use the lines as general-purpose digital I/O or as control lines for alarms. Each line sinks or sources 8 mA. With the TBX-68T or CB-68T, you can increase the sinking and sourcing capability of these digital lines to 64 and 15 mA, respectively. With digital signal conditioning accessories, such as the ER-8, SSR Series, and the SC-206x, you can use an NI 4351 to control relays and drive optically isolated digital I/O.
