The DCI System allows for acquisition and coordination of thermal experiments from many popular thermal analyzers. The system replaces the existing computer and interface with a Data Collection Interface (DCI) and the Windows software. The DCI has three channels of high resolution analog inputs. These inputs connect to your existing analyzer to collect temperature and Y axis signals. The DCI also has three relays which provides remote instrument heat, hold and cool activation controlled by the software. In addition the DCI has one relay to operate gas switching devices so gases can be changed during the thermal experiment.
