Introduction
The ET-7218Z series modules are designed for high-precision thermocouple measurement. Each input channel provides automatic cold-junction compensation to ensure consistent and stable temperature readings in the field.The modules include open thermocouple detection as well as EMS (EFT/ESD/Surge) protection. In addition to supporting multiple thermocouple input types, every input channel can also be individually configured for current or voltage input, delivering optimal flexibility for a wide range of application requirements. This series also offers digital output channels, each equipped with short-circuit and overload protection.
