National Instruments 777459-22

The National Instruments 777459-22 Analog Input Module, designated as the SCC-AI03, is a high-performance isolated analog input solution featuring two isolated channels. Designed to operate within an input range of ±10 V and an input impedance of 100 MΩ, this module ensures minimal signal degradation and accurate measurements. It is compatible with SC-2345, SC-2350, and SCC-68 models, facilitating seamless integration into existing systems by connecting through the analog sockets of these devices. The module operates with E/M Series DAQ channels, allowing configuration through the Measurement & Automation Explorer (MAX) software.

With a default gain setting that users can adjust, the 777459-22 can be utilized in conjunction with another SCC analog input module on a single channel, enabling the simultaneous application of filtering and attenuation to an analog input signal. The integrated filter offers a 3-pole configuration with a rolloff of 60 dB per decade and a cutoff frequency of 10 kHz, making it suitable for a wide range of sensors, including RTDs, thermocouples, and pressure sensors. The module features a 20-pin right-angle male connector and a 4-pin screw terminal for robust connectivity. It consumes up to 410 mW for analog power and 650 mW for digital power, delivering reliable performance for industrial automation applications. The 777459-22 provides two Non-Referenced Single-Ended (NRSE) input channels, designed to accommodate signal ranges from ±50 mV to ±42 V.
