National Instruments 777687-32 Matrix Terminal Block 

Part Number 777687-32 is the identifying part number for the National Instruments SCXI-1332 Matrix Terminal Block. To set up the 777687-32 with a suitable switch module like the SCXI-1127 or the SCXI-1128, you will need the following accessories: an SCXI chassis, an â…› in. flathead screwdriver, Number 1 and 2 Phillips screwdrivers, long-nose pliers, wire cutter, wire insulation stripper, and matrix expansion cables, where one cable is needed to expand the number of columns, and two cables are needed to expand the number of rows.

To connect signals to the 777687-32, the signal wire is first prepared by stripping an insulation of no more than 7mm. Then, the top screw and the screw cover are removed and the strain-relief screws on the strain-relief bar are loosened. The signal wires are then run through the strain-relief opening. When the stripped end of the wire is fully inserted into the terminal, the wire is secured by tightening the screw. Note that no bare wire should extend past the screw terminal as this can cause short circuits. Lastly, the safety earth ground is connected to the safety ground lug, and the screws and the top covers are restored. 

The 777687-32 has a maximum voltage (between channel-to-ground) of 300 V, CAT II. Likewise, the terminal block features 1390 Vrms isolation between input signals and chassis as verified by a dielectric withstand test at a 1-minute maximum. The terminal block should not be used for signal connections and measurements within Categories III or IV. Furthermore, the terminal block has a maximum current of 2 ADC, and 2 AAC per channel. 

The 777687-32 has an operating temperature of 0 °C to 50 °C and a storage temperature of -20 °C to 70 °C. Likewise, the terminal block operates at a relative humidity of 10 % to 90 % RH, non-condensing. The maximum altitude for the operation of the module is 2,000 m with an indoor pollution degree equaling 2. The terminal block complies with the safety standards: IEC 61010-1, EN 61010-1, UL 61010-1, and CAN/CSA C22.2 No. 61010.1 as electrical equipment for measurement, control, and laboratory use.
