Description
The product comes with two distinct part numbers, 784788-01, which offers 60 Vrms Channel-to-Earth Ground Isolation and is equipped with a Mini-TC connector, and 785043-01, providing 250 Vrms Channel-to-Earth Ground Isolation with a Spring Terminal connector. Both models are designed to seamlessly integrate with CompactDAQ/CompactRIO systems, ensuring compatibility and ease of use across various applications.
One of the key features of this product is its NIST-traceable calibration, guaranteeing accurate measurements that adhere to national standards. The device is built with a dual isolation barrier for enhanced safety and reliability during operation. It supports a range of input types, including both thermocouples and RTDs, making it versatile for different temperature measurement tasks.
This device boasts 4 differential analog input channels, allowing for multiple simultaneous measurements. It employs a Delta-Sigma ADC with a 24 bits resolution, ensuring high-precision data conversion. The sampling mode is scanned, designed for efficient data collection.
The input voltage range of +/-80 mV accommodates various sensor outputs, while the conversion time stands at 70 ms/channel, optimizing the balance between speed and accuracy. With an input bandwidth of 15 Hz at -3dB and a minimum noise rejection of 85 dB, the device ensures clear, reliable measurements even in noisy environments.
Added safety features include overvoltage protection up to +30 V, guarding the device against unexpected voltage spikes. It also features internal channels for measurement accuracy, such as an auto zero channel and a cold junction channel, with the former being optional, to further enhance the precision of temperature readings.
