Description
10-channel Thermocouple Input Module
The “Z” version is another milestone in the development of I-7018 and a testament to excellence by ICP DAS R&D team. I-7018Z is specifically designed for extremely accurate thermocouple measurement. It features automatic cold-junction compensation for each channel. Current input and voltage input are supported. Another feature is that ten of its input channels can individually be confi gured with different kinds of analog input. I-7018Z also has open thermocouple detection and many protection mechanisms.
