National Instruments 777459-22 Analog Input Module 

National Instruments part number 777459-22 is an identifying part number for the SCC-AI03, an Isolated Analog Input Module with 2 Isolated Channels with Input Range of ±10 V and Input Impedance of 100 MΩ. The NI 777459-22 is compatible with SC-2345/2350 or SCC-68 models and can be inserted into the analog sockets of these devices. Depending on the socket used, the E/M Series DAQ channels on the device will receive the signals from the NI 777459-22.

This device can be configured using the MAX (Measurement & Automation Explorer) tool. This Isolated Analog Input Module is preset with the gain set to its default limit. However, users can adjust the gain using their E/M Series DAQ device. Additionally, the 777459-22 can be used alongside another SCC analog input module on a single analog input channel. This allows users to pass an analog input signal through both a filter module and an attenuator module simultaneously. 

The NI 777459-22 filter includes a built-in filter with 3 poles and a rolloff of 60 dB per decade, featuring a cutoff frequency of 10 kHz. It is compatible with RTDs, thermocouples, pressure sensors, and various modules and carriers. The device is equipped with a 20-pin right-angle male connector and a 4-pin screw terminal. It consumes a maximum of 410 mW for analog power and 650 mW for digital power. It offers 2 NRSE (Non-Referenced Single-Ended) input channels with an input impedance of 100 MΩ.
