The National Instruments SCXI-1166 is a general-purpose switch module with 32 channels. It has independent SPDT (Form C) nonlatching relays with very low on-resistance and low thermal offset. The NI SCXI-1166 can switch up to 2 A at 30 VAC/30 VDC and can carry 5 A per channel. Hence, it is ideal for switching, routing, and controlling high-current signals. Each relay channel has a normally closed (NC), normally open (NO), and common (COM) terminal.
