NI SCXI-1313A Terminal Block

NI SCXI-1313A Terminal Block

DESCRIPTION

The SCXI-1313A terminal block is shielded and has screw terminals that provide input connections for the SCXI-1125. Each SCXI-1313A channel has a precision 100:1 resistive voltage divider that you can use to measure voltages of up to 150 Vrms or ±150 VDC. You can individually bypass these voltage dividers for low-voltage measurement applications. The terminal block has 18 screw terminals for easy signal connection. One pair of screw terminals connects to the SCXI-1125 chassis ground. The remaining eight pairs of screw terminals connect signals to the eight analog inputs.
