National Instruments BNC-2144 PXI Terminal Block

With 32 analog input channels, the BNC-2144 (part number: 779763-01) from National Instruments is a PXI Terminal Block specifically designed for use with the NI PXI-449X family of products. Offering high performance for testing and debugging, the BNC-2144 facilitates connections to compatible PXI Sound and Vibration Devices. Equipped with a 19 inch rack-mount adapter, the BNC-2144 easily integrates into existing test setups. Typically, the maximum cable length for the device measures 61 m (200 ft). For enhanced I/O connectivity, the terminal block has 32 BNC connectors in addition to 4 Infiniband 4x connectors.

The maximum input voltage for the analog input of the BNC-2144 PXI Terminal Block measures ±10 Vpk for the positive terminal and ±1 Vpk for the negative terminal. These terminals are safeguarded against potential damage with ±30 Vpk of overvoltage protection included for the positive terminal and ±5 Vpk of protection for the negative terminal.

Designed to be operated indoors only, the BNC-2144 should be used in environments where the temperatures range from 0 to 55 °C. When not being used, the terminal block can withstand environmental storage temperatures ranging from –20 to 70 °C. For both the operational and nonoperational states of the device, the noncondensing relative humidity should stay within a range of 10 to 90%.

The BNC-2144 PXI Terminal Block measures dimensions of 48.3 × 4.4 × 6.4 cm (19.0 × 1.7 × 2.5 in.) and weighs in at 0.89 kg (1.96 pounds). It can be operated effectively at altitudes up to 2,000 m, and it has a pollution degree of 2.
