Description
The National Instruments TBX-1326 High-Voltage Terminal Block, with Part Number 777207-26, features 48 screw terminals organized into 8 groups, each group comprising 6 terminals including 1 ground (GND), 1 positive supply voltage (Vcc), and 4 signal channels.
This terminal block is designed for compatibility with several modules, including the SCXI-1163, SCXI-1162HV, SCXI-1162, and SCXI-1163R. It connects through an SH48-48-B cable and supports convenient signal wiring with labeled rows A, B, and C.
For mounting, it is fully compatible with DIN EN 50 022 and DIN EN 50 035 DIN rails. The terminal block’s versatility allows it to serve various functions depending on the module it’s paired with; for instance, with the SCXI-1162, the Vcc terminal is used for power or reference voltage, the CH(X) terminals for digital input signals, and the GND terminal remains unused.
When used with the SCXI-1162HV, the GND terminal provides a ground reference and the CH(X) terminals are used for the input signal, leaving the Vcc terminal unused. The SCXI-1163 module utilizes all terminals, with Vcc for power supply, GND for ground, and CH(X) for digital output signals. Lastly, in combination with the SCXI-1163R, the Vcc terminal is again unused, GND serves as a common pole, and CH(X) is used for relay inputs.
