National Instruments 776572-25 Voltage Input Module for SCXI
National Instruments' 776572-25 is an isolated voltage input module with eight channels that is a member of the SCXI-1125 Model series. With 300 Vrms operating isolation per channel, it has been designed for thermocouple, millivolt, volt, and current signal conditioning and isolation, ensuring both signal integrity and safety. Every channel has a lowpass filter that can be adjusted to either 4 Hz or 10 kHz, and it has 12 programmable gain levels that range from 1 to 2000.
This module is ideal for isolated temperature measurements from thermocouples. It has a multiplexed scanning capability for the cold-junction compensation (CJC) channel, which guarantees accurate temperature readings. Because the 776572-25 supports both parallel and multiplexed output modes, data handling and transmission are flexible. It increases the channel count of the DAQ system by multiplexing all channels into a single channel of a controlling DAQ device.
Onboard EEPROM for nonvolatile software correction consistent storage of offset and gain makes periodic calibration easier for the 776572-25. Measurement precision is maintained throughout time by the programmable offset-nulling circuit, which guarantees precise offset calibration.
The 776572-25 is a jumperless variant of the SCXI-1120 that offers improved functionality and backward compatibility with SCXI-1120 applications. It supports a number of application development environments (ADEs), including LabVIEW, BridgeVIEW, LabWindows/CVI, Visual Basic (ComponentWorks), C, and C++ environments, and is compatible with the NI-DAQ data acquisition device driver software. For even more application adaptability, it can be combined with Measure and VirtualBench.
The module offers strong overvoltage protection whether it is switched on or off, with a maximum working voltage of 300 V rms or VDC between channels and from channel to ground. It is appropriate for a range of measurement purposes because the default input coupling is DC. It is intended to work in conditions of 10 to 90% noncondensing relative humidity, operating within a temperature range of 0 to 50 °C and a storage temperature range of –20 to 70 °C.
