The 777966-81 SCXI-1581 32 ch, 100 uA Current Excitation Module from National Instruments is a highly precise and reliable Analog Output Module. It features 32 channels with 100 µA current excitation, making it perfect for measuring resistance with extreme precision. The module can be used with terminal blocks such as the SCXI-1300, SCXI-1310, BNC-2095, or TBX-96 for various connection options. It is important to note that when the SCXI-1300 is connected to the SCXI-1581, the onboard temperature sensor cannot be measured. This module is ideal for applications requiring a 100 µA fixed current excitation, such as RTDs and thermistors, and can be used in combination with the SCXI-1102 for high-channel-count RTD measurement systems. The SCXI-1581 also features a signal connector for communication with an E/M Series DAQ instrument, allowing for transmission of analog signals in multiplexed mode. Despite its obsolete status, the module is still available for purchase and repairs through Apex Waves, with the part number 777966-81.
