Digital Signal to 4~20mA Analog Signal Converter
Brief Introduction
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.
Configuration
NCS-FI105 transmitter can be configured by the Configurator software and NCS4000 DCS software of Microcyber Inc, NI-FBUS Configurator of National Instrument, and DeltaV system of Rosemount.
