Product Description

Important: FieldQ QC Control Modules are now obsolete. The FieldQ actuator is still available, and it can be used with standard controls via the NAMUR adapter plate. Starting in 2019, the FieldQ actuator design was updated. In our documentation, the older design is referred to as Release 1, and the newer version as Release 2.
