Description
The National Instruments NI-9945 Terminal Block is a versatile accessory designed for use with the NI-9237 Strain Bridge Input Module, offering compatibility with shielded cables to ensure minimal noise interference during data acquisition. Available in two versions, the standard Part Number 194739-01 and the high accuracy Part Number 194739-02, this terminal block is essential for those requiring precise measurements.
Installation of the NI-9945 is straightforward, requiring a plastic tie strap for secure strain relief and an M4x20 screw for proper mounting. With its robust design, the terminal block operates reliably within a wide temperature range of -40 °C to 70 °C.
The terminal block boasts a resistor value of 350 Ω and maintains measurement stability with a resistance drift of merely 0.0035 Ω/°C. Precision is further assured by its resistor tolerance, which is tightly controlled to a maximum of 0.1% at 25 °C.
Constructed to handle a maximum resistor power of 0.25 W, the NI-9945 is both efficient and space-saving, with dimensions of 2.6 in. × 0.85 in. × 0.90 in. and a lightweight profile at just 1.1 oz, making it an ideal choice for a variety of applications where space and weight are at a premium.
