NI SCXI-1326 SCXI Terminal Block

The NI SCXI-1326 is a high-voltage terminal block designed for field wiring integration with National Instruments SCXI signal conditioning modules. It provides 48 screw terminals arranged in eight isolated groups, each containing VCC, GND, and four signal channels, enabling reliable connection of high-voltage signals to SCXI-1162, SCXI-1162HV, SCXI-1163, and SCXI-1163R systems. The shielded design and 300 V rating make it suitable for digital I/O, voltage measurement, and temperature sensing applications across distributed channel architectures.
