Introduction
The “Z” version is another milestone in the development of the thermocouple series and is a testament to the excellence of ICP DAS products.
The ET-7018Z/PET-7018Z/ET-7218Z/PET-7218Z is specifically designed for extremely accurate thermocouple measurement and features automatic
cold-junction compensation for each channel to ensure temperature output consistency and stable temperature output in the field. Current input
and voltage input are both supported. Another feature is that its ten input channels can be individually configured for different kinds of analog input.
Open thermocouple detection and ESD/EFT/Surge protection mechanisms are also included. The six/five digital output channels can be set as alarm
outputs with short-circuit protection and overload protection.
