The National Instruments SCXI-1161 is a general-purpose switching module consisting of eight independent SPDT (also called Form C) nonlatching relays. They can switch up to 8 A at 125 Vrms, 6 A at 250 Vrms, or 5 A at 30 VDC, making them suitable for higher power applications. Each channel has a normally closed (NC), normally open (NO), and common (COM) terminal. You can use two or more NI SCXI-1161s (and SCXI-1160s) in the same chassis with a single DAQ device or switch controller. The DAQ device controls these SCXI modules through serial communication over the SCXIbus in the backplane of an SCXI chassis. The NI 4021 switch controller or the NI 40470/4060 DMMs control these SCXI modules via the SCXI-1362 cable assembly.
