National Instruments Corporation 777697-01 NI PXI-2503 24 ch Relay Multiplexer and Matrix Switch

The National Instruments PXI-2503 performs as a multiplexer or matrix switch. It switches signals up to 60 VDC or 30 Vrms. For low-voltage measurements, such as thermocouple signals, the NI PXI-2503 relays have very low thermal offset (less than 2 V) for accurate measurements. For automotive-level voltage measurements, the PXI-2503 handles up to 1 A at 30 VDC.
