NI TB-2635 Terminal Block
The TB-2635 Terminal Block (Part Numbers: 189429-01L, 189429B-01, and 778839-01) is designed to be used with the PXI-2529 – a high-density Matrix Switch Module from National Instruments. This accessory allows the configuration of the matrix switch as a 2-wire, 8 x 16 matrix. A switching system consisting of this accessory and a matrix switch offers direct, hard-wired signal connectivity to the screw terminals residing inside the NI TB-2635.
This Terminal Block comes featured with an integrated strain-relief bar and safety ground lug. A pair of jackscrews is also provided for a firm connection between the Terminal Block and the Matrix Switch Module. The TB-2635 is designed for CAT I systems because it is intended to carry up to 150 V signals. However, it is tested to withstand as high as 800 V of surge or impulse voltage. The installation of this Terminal Block is a simple task and can be done without professional assistance.
