NCS-IF105 Current to Fieldbus Converter Wiring Shown:
As the core of NCS-IF105 converter, the Communication Card connects with terminal board, isolation board, instrument board and LCD board. The LCD board rotated in four angles is fixed on the Communication board, as Figure shows.
Current to Fieldbus Converter Principle and Structure
NCS-IF105 converter convert input current signal that generate by most conventional transmitters to fieldbus signal.
NCS-IF105 converter is consisted of five components, as shown in Figure.
1) Terminal board: it is used to connect with fieldbus, current output signal, A/D board and communication board.
2) A/D board: it can convert input current signal to digital signal provided to communication board.
3) Communication card: it is core component of intelligent instrument, which implements the communication, control, diagnosis and maintenance of Foundation Fieldbus.
4) Isolation board: it is used for isolation between communication board and instrument board (power isolation and signal isolation).
5) LCD Card (optional): it is used to display function block parameters.
