Converter Digital Signal to Analog Signal     NCS-FI105 fieldbus to current Converter is used to convert fieldbus signals to conventional analog signals. It can receive fieldbus signals, and convert them to 4-channel 4~20mA analog signals. NCS-FI105 is the converter between fieldbus system and control valve/other actuator.   NCS-FI105 is an intelligent instrument and complies with FF Fieldbus Specification. It can be interlinked with several FF equipment. Abundant function blocks are integrated into NCS-FI105, and so it can complete not only the general measuring but also the complex controlling strategy. According to the requirement and actual application environment, the users can choose different function blocks to implement different function.   NCS-FI105 utilizes digital technology, which simplifies the interface between the control center and the field equipment. And so the expense of installing, running and maintenance can be reduced.   Priciple and Structure   Size of NCS-FI105   Structure of NCS-FI105       Technical Specification   1) Basic Parameters
